As of September 29, 2026, Wanlin Group (Shenzhen, China) officially launches its 2026 Hong Kong wireless fire alarm system export programme, featuring the WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink as the flagship OEM and ODM component for overseas buyers, cross-border trading companies, EPC contractors, main contractors running phased handovers, facility management groups, hotel and hospital estates, retail and mall operators, university and school districts, warehouse and logistics operators, road and rail transport authorities, heritage property owners and regional importers who source Hong Kong wireless fire detection hardware from a China-based source factory under the Wanlin brand. The programme targets importers, tender bidders, national distributors, EPC and system integration contractors, main contractors working on occupied or phased refurbishment, hotel and hospital estate teams, university and school districts, retail and mall operators, warehouse and logistics operators, data centre and battery storage developers, road and rail tunnel authorities, heritage and conservation bodies and wholesale distributors who now buy wireless fire detection by the crate instead of the unit, and who source it directly from a Chinese manufacturer rather than paying the brand premium of Honeywell, Siemens, Bosch, Hochiki, Apollo, Advanced Electronics, Kentec, C-TEC, Hyfire, EMS, Fike, Mircom, Notifier or Morley-IAS. Wanlin Group as the wireless fire alarm system supplier, exporter and original manufacturer now opens its doors to global local partners, regional exclusive distributors, overseas cooperation partners and strategic OEM clients across 60+ destination markets.
Working principle: supervised wireless device supervision with cause-and-effect programming, dual-path alarm transmission and a non-volatile event log. Output signal: 4G LTE Cat-1 plus Wi-Fi 2.4 GHz plus 10/100 Ethernet, with Modbus TCP, MQTT and a dry contact fire and fault relay set, which the gateway acknowledges with confirmed delivery rather than best-effort transmission. Coverage area: up to 1,000 wireless devices across 32 zones, extended by 868D gateways for multi-building campuses, which is the figure the per-floor detector count is derived from at desktop stage, before anyone climbs a ladder. Alarm output: two supervised sounder circuits plus fire and fault relays, normal mode sounding every unit within 60 s of any trigger, password-protected investigation mode holding the general alarm 5 min and cancelling automatically if a second device on the same floor activates, test and evacuation modes, an unattended alarm escalation timer set to 10 min, and named group notification through WhatsApp, SMS, email and voice covering 30 recipients with a 5,000 message per year baseline, which is what wakes a household at three in the morning in a building where the single staircase is the only escape route. IP rating: IP30 control cabinet indoor, IP54 with the gasketed door kit for plant rooms, which is why kitchens and plant rooms are quoted on a different enclosure variant from living rooms. Operating temperature: 0 deg C to +45 deg C, optional cabinet heater to -20 deg C, which covers unconditioned staircases, rooftop plant rooms and the corridor that never sees air conditioning. Humidity range: 10-90% RH non-condensing, which is the range the chamber drift compensation is verified across before shipment. Housing material: 1.2 mm cold-rolled steel cabinet with an epoxy powder coat, hinged lockable door and a 7-inch touch HMI, which survives the cleaning regime a ground-floor food premises imposes on the common parts. Dimensions and weight: 520 mm x 420 mm x 160 mm, 12.5 kg net including batteries, which is small enough to mount on a subdivided unit ceiling without a new fixing plate. Alarm threshold: fire, fault, pre-alarm, supervisory and test states per device, with user-configurable cause-and-effect matrices across 32 zones, set so that one criterion raises a pre-alarm while confirmed smoke plus carbon monoxide raises the fire signal. Accuracy class: EN 54-2 and EN 54-4 control and indicating equipment, GB 4717 CCCF, 1,000 supervised device registrations, 50 concurrent browser users on the web console, 10,000-entry non-volatile event log with a real-time clock, which is the class written into the acceptance file before the device count is signed off. Certifications: EN 54-2 / EN 54-4 / EN 54-21 / CE / RoHS / REACH / FCC / GB 4717 CCCF / UL 864 on request.

This article is written for B2B buyers in Tsz Wan Shan, Hong Kong SAR who judge a IoT fire detection system package on availability rather than on features: how much radio margin each device carries after the last partition went up, how many years of real duty the cell gives at the site temperature, how quickly the platform names the device and its exact location, and whether an investigating person can hold the general alarm long enough to check without missing a real fire. Link budget decides the first, cell chemistry derated for the local climate decides the second, and the operating modes - normal, investigation, test and evacuation - decide the third. Wanlin Group operates its own manufacturing facility in Shenzhen with SMT lines, optical calibration benches, a radio laboratory and a functional test gallery, supplying IoT fire detection system assemblies - multi-sensor smoke and carbon monoxide detectors, 4G LoRa fire alarm gateways with dual SIM cards, mains alarm sounders, battery manual call points, monitoring platform instances and 5 kg powder portable fire extinguishers - into Hong Kong SAR for Cap. 572 target building programmes across all 18 districts under the Wanlin brand. Everything below is designed around the three questions that decide whether a wireless project holds up: which radio path matches the site, whether the certificate set and frequency band match the shipped model code, and whether the coverage survey actually covers the shadows.
An IoT fire detection system, abbreviated IoT FDS, is the complete fire detection and alarm arrangement accepted by the Hong Kong Fire Services Department under Circular Letter No. 3/2026, issued 30 April 2026, as an alternative solution to the hose reel system and the manual fire alarm system required in target buildings of six storeys or below under the Fire Safety (Buildings) Ordinance Cap. 572. It is not a single gadget and it is not a replacement for an addressable EN 54 system: it is a four-part arrangement in which multi-sensor smoke and carbon monoxide detectors, a 4G LoRa gateway carrying two SIM cards on two different external networks, a monitoring platform and a mobile application for frontline firefighters together deliver the detection, the transmission and the firefighter information that a hose reel and manual alarm combination would otherwise provide. Only those two items are replaced. Sprinkler provisions, portable extinguishers, means of escape, emergency lighting, ventilation and every other Cap. 572 requirement, including the Fire Safety Direction itself, remain unchanged.
For a buyer in Tsz Wan Shan, Hong Kong SAR, the definition reduces to five statements that can each be tested on site rather than read off a brochure. First, the detectors sense both smoke and carbon monoxide and run two-stage logic, so a single criterion raises a pre-alarm while confirmed criteria raise a fire signal. Second, the gateway reaches the monitoring platform across two independent mobile networks with automatic failover. Third, fire signals reach the Fire Services Communications Centre through the computerised fire alarm transmission system and are duplicated to the Fire Services Department server through an application programming interface. Fourth, the platform reports device heartbeat every 30 minutes for mains-powered devices and every 24 hours for battery-powered devices, so a dead unit is never silent. Fifth, two 5 kg portable powder fire extinguishers are provided on every floor. The WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink supplied by Wanlin Group is engineered to that definition, with supervised wireless device supervision with cause-and-effect programming, dual-path alarm transmission and a non-volatile event log.
Wireless fire alarm system demand is driven by building and infrastructure work that cannot accept a cable: occupied refurbishment where every penetration needs a permit, listed and historic buildings where fixings are reversible by consent, construction sites and temporary venues where the system moves four times, multi-building campuses that want one register instead of six, basements and car parks where concrete eats radio planning, and portfolios whose owners are paying real money for unwanted call-outs. Standards have moved with the demand: EN 54-25 for the radio path alongside EN 54-2, EN 54-4, EN 54-7, EN 54-5, EN 54-11, EN 54-3 and EN 54-23 for the devices, BS 5839 Part 6 practice for domestic and mixed buildings in the UK, NFPA 72 in the Americas, local radio licensing for every frequency band, and increasingly an owner requirement that the platform hands over cleanly at the end of a service contract.
Market access in Tsz Wan Shan, Hong Kong SAR is anchored on documentation set prepared for the Fire Services Department submission in Wong Tai Sin District: the IoT FDS application intent form reference, the EN 54-7 smoke and EN 54-5 heat type-test file, the EN 54-25 radio component declaration, the OFCA short-range device record for the LoRaWAN and 4G control link, the FS251 certificate template and the bilingual Traditional Chinese and English label artwork printed at the factory. Multi-sensor smoke and carbon monoxide detectors, 4G LoRa fire alarm gateways with dual SIM cards, mains powered alarm sounders, battery manual call points and the 5 kg powder portable fire extinguishers are shipped into Tsz Wan Shan, Hong Kong SAR on one HS-coded packing list: the Fire Services Department submission file, the OFCA short-range device documentation, the EN 54 type-test references, the CE and RoHS declarations and the per-unit battery autonomy record travel with the pallet, so the registered fire service installation contractor signs the FS251 certificate without a second shipment or a re-test at destination, which requires a documented conformity route, a declaration referencing EN 54-2, EN 54-4 and EN 54-25 as applicable, a radio band approval matched to the shipped model code and third-party approval body involvement where the scheme demands it. Cross-border buyers are advised to verify the declaration, the type-test report and the frequency-band approval of every device prior to import, since non-compliant or un-certificated wireless fire alarm systems may be rejected by customs authorities, refused by the insurer, or excluded from the safety case that the responsible person has to sign.
Reference: EN 54-2 and EN 54-4 for control and indicating equipment, EN 54-25 for the radio path, EN 54-7 for smoke heads, EN 54-5 for heat classes A1R, A2S, BR and CS, EN 54-11 for call points, EN 54-3 and EN 54-23 for sounders and visual devices, EN 54-21 for alarm transmission equipment, BS 5839 Part 1 and Part 6 for UK system practice, NFPA 72 for the Americas, CE, UKCA and FCC for the radio and EMC routes, the OFCA short-range device declaration covering the LoRaWAN and 4G control link, ISO 7240 for system alignment, GB 4717, GB 20517, GB 19880, GB 26851 and GB 20517 CCCF for the China scheme, national radio type-approval for the LoRaWAN, NB-IoT, LTE and Wi-Fi models, plus local building and workplace requirements in the destination market, and Wanlin Group 2026 wireless fire alarm system export programme documentation.
The WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink is engineered inside a four-layer wireless fire alarm architecture rather than as an isolated device: (1) a sensing layer using dual-criteria smoke and heat elements with coincident confirmation, because most unwanted activations come from steam, cooking and dust rather than from faults; (2) a radio layer with a declared link budget and a frequency plan legal for the destination band, because a device that reaches the gateway by 3 dB is a device that stops reaching it the day someone installs a steel partition; (3) a power layer choosing per site between wide-input mains with a declared ride-through time and lithium cells whose service life is quoted for the local temperature rather than for a laboratory bench; and (4) an evidence layer holding the event log, per-device battery and signal history and weekly server backups, because the insurer, the enforcing authority and the maintenance contractor all argue less when the data series is attached to the file. Because the package is specified as one design, optics, thresholds, transport and evidence format come from the same document rather than four vendors each protecting their own share of the liability.
Three sub-modules define the engineering depth:
The featured model is WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink, part of the Wireless Fire Alarm Control and Indicating Equipment (4G / Wi-Fi / Ethernet) family, configured as the 4g lte cat-1 build (1 variant). FOB Shenzhen reference price is $285.00 per piece at MOQ 20 pcs, with bulk tier pricing ranging $247.95-$316.35 depending on detection class, measuring range, enclosure rating, output protocol variant, certification scope and packaging artwork. Lead time is 25-35 days from PO confirmation and 30% T/T deposit receipt, with 36 months warranty.
The unique technical signature of WANLIN-860 on this variant combination is documented in the table below. Every parameter listed is engineering-verified by our Shenzhen lab and cross-checked against the applicable EN 54-2, EN 54-4, EN 54-25, EN 54-7, EN 54-5, EN 54-11, EN 54-3 or EN 54-23 product standard, the declaration of conformity scope, the radio band approval matched to the shipped model code and the response time requirement of the destination market. Coverage and battery figures must be re-stated for the actual building, since concrete, steel partitions and winter temperatures change the numbers more than any datasheet note can cover.

Buyers comparing quotations should read the signal chain rather than the datasheet. The chain below is the one Wanlin engineers against for Tsz Wan Shan target buildings, and it is the same chain the department evaluated when it recorded zero false alarms, 100 percent device availability and a heartbeat compliance figure above 99.95 percent across the ten pilot buildings in the first quarter of 2026. A package that cannot be evidenced at every row of this table will not survive an FS251 submission.
| Step in the chain | Mechanism | Requirement or recorded result |
|---|---|---|
| Detector evaluates smoke and carbon monoxide | Two-stage logic on the multi-sensor head; single criterion gives a pre-alarm, confirmed criteria give a fire signal | Pilot scheme result: 0 false alarms |
| Detector to gateway | LoRaWAN uplink with confirmed delivery and retry, supervised radio stack | Within 10 s |

| Battery-powered device heartbeat | Supervisory ping on a 24 hour cycle with a low-cell warning ahead of end of life | Every 24 h |
| Mobile application push to frontline firefighters | Device location, floor and status delivered to the responding crew | On fire signal |
| Monthly performance report | Availability, heartbeat compliance and false-alarm count issued to the owner and the department | Monthly |
Every WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink shipped into the programme is provisioned against that chain before it leaves Shenzhen: SIM profiles loaded and tested, the platform tenant created, the heartbeat class set to match the power source, the cause-and-effect matrix exported as a PDF, and the device serial register issued in the same format the maintenance contractor will use for the next three years.
Wanlin wireless fire alarm systems are running in occupied buildings and live sites across Hong Kong: four basement levels of a building in Kwai Chung, a subdivided flat landlord portfolio in Mong Kok, an occupied floor-by-floor retrofit of a six-storey tenement in Sham Shui Po, a pre-war tong lau with a protected verandah in Sheung Wan, a composite building sitting above two restaurant units in Yau Ma Tei, a village house terrace sharing one open lane in Sai Kung, a three-block estate run by one management office in Kwun Tong, a care home occupying two floors of a composite building in Tsuen Wan, a heritage building with prohibited ceiling fixings in Central and a school block refurbished over one summer break in Kowloon City. Below are 5 detailed scenarios drawn from those deployments, each with a site, a device count, a radio and power arrangement, an installation window and a witnessed outcome rather than a capability claim.
Scenario 1: Building in a pilot-scheme district, Hill Road, Sai Wan, Central and Western District, Hong Kong SAR. Central and Western was one of the ten districts covered when the Fire Services Department installed IoT fire detection systems in ten selected target buildings of six storeys or below in the fourth quarter of 2025 and evaluated them from 1 January to 31 March 2026. The published results were zero false alarms, 100 per cent system availability and better than 99.95 per cent effective component operation. A building on this street runs the same pattern the pilot measured: mains-fed common-area devices reporting heartbeat every 30 minutes, battery devices every 24 hours, fault within 20 s and status within 100 s, with the main contractor filing a monthly performance report that is the document the department actually reads rather than the commissioning certificate. Fault triage on this site resolved 4 events in 46 months, of which the two that reached a full investigation were traced to a blocked louvre in a plant room, and the platform never raised a supervisory fault that turned out to be a real device failure.
Scenario 2: Single-staircase tenement with elderly tenants, Ngo Cheung Street, To Kwa Wan, Kowloon City, Hong Kong SAR. One staircase, twenty-three households, and a resident profile where a full evacuation takes considerably longer than a drill sheet assumes. The design answer is the two-stage logic plus the mobile application: a single-criterion pre-alarm goes to the floor warden and the owners' group, and only smoke-and-carbon-monoxide coincidence or a second confirming device escalates to a building-wide alarm and a transmission to the Fire Services Communications Centre. On arrival, the crew opens the application and sees which device triggered, which floor it sits on and when it last reported a heartbeat, instead of knocking on twenty-three doors. The measured end-to-end time from detector threshold to signal acknowledgement at the communications centre was 8 s on the mains-fed landing devices during the acceptance test. Spares holding for this site sits at 7 percent of the installed population, sized against a 7-month battery replacement round rather than a full panel swap.
Scenario 3: Ground-floor cafe with a rear extraction duct under the flats, Castle Peak Road, Tsuen Wan, Hong Kong SAR. A five-storey block with a cafe below and a duct that discharges directly under the staircase soffit. This is the layout that produces the most nuisance activations in the whole programme, so the detector nearest the duct was specified on the lower sensitivity level and the two-stage logic was set to hold a pre-alarm for a fixed investigation window before any general alarm. The kitchen extraction was logged as a known cause in the cause-and-effect matrix so the fire brigade sees it on the mobile application rather than discovering it at the door. Fire brigade liaison accepted the WANLIN-860 cause-and-effect matrix after a witnessed test across 109 devices, with the investigation hold set to 7 minutes to suit the local response plan.
Scenario 4: Industrial building with a subdivided upper floor and a goods lift lobby, Kwai Chung Road, Kwai Tsing, Hong Kong SAR. A 1970s industrial block where the upper floor has been cut into six workshop units, each with its own roller shutter and its own lock-up. The non-domestic units are counted separately from the common areas, so the detector density is set by use rather than by floor area alone, and the goods lift lobby gets its own device because it is the one space every tenant passes through and the one space nobody owns. Fault triage on this site resolved 3 events in 15 months, of which the two that reached a full investigation were traced to a blocked louvre in a plant room, and the platform never raised a supervisory fault that turned out to be a real device failure.
Scenario 5: Old estate block with a single riser shaft and no spare capacity, Shau Kei Wan Road, Eastern District, Hong Kong SAR. A public estate block built before the current fire safety code, with one riser that is already full and a management office that will not authorise a second penetration. Nothing in this design touches the riser: the detectors run on sealed cells, the gateway sits in the existing management office on mains with battery backup, and the whole installation was completed without a single new hole through a structural wall. Spares holding for this site sits at 6 percent of the installed population, sized against a 19-month battery replacement round rather than a full panel swap.
Scenario 6: School annexe awaiting an improvement grant, Tsing Yi Heung Sze Wui Road, Kwai Tsing, Hong Kong SAR. A three-storey annexe used for storage and two classrooms, occupied during term and shuttered in the summer. The problem is not detection, it is evidence: the grant file needs a cost breakdown the scheme will accept, so the quotation was split into device supply, installation, transmission service and maintenance rather than bundled into one line, which is what allowed the application to be assessed at all. Fire brigade liaison accepted the WANLIN-860 cause-and-effect matrix after a witnessed test across 148 devices, with the investigation hold set to 3 minutes to suit the local response plan.
The two-week programme the department quotes is achievable because almost none of the work touches the structure. The sequence below is the one Wanlin project teams hand to the registered fire service installation contractor, and it is written so that a WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink installation can be evidenced line by line at FS251 stage instead of being reconstructed from memory.
Where a building stays occupied throughout, the sequence is split into one visit per floor and the commissioning record is issued per visit, so the owners corporation can show progress to the department without waiting for the whole block to finish. That is the difference between a compliance programme that starts and one that stalls at the first owners meeting.
The WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink and the wider Wanlin wireless fire alarm system programme deliver 10 distinct advantages for cross-border B2B buyers who source wireless fire detection hardware directly from a Chinese manufacturer:
Combined, these advantages allow Wanlin partners to win occupied refurbishment packages, heritage and listed building retrofits, construction site and temporary venue systems, campus and multi-building frameworks, warehouse and logistics programmes, hotel, hospital and education estate retrofits, car park and transport authority tenders, industrial and mining shutdown work, and national distributor frameworks, secure regional distribution rights and serve end customers under their own brand at 45-65% lower landed cost compared to legacy western distribution channels.
The WANLIN-860 Wireless Fire Alarm Control Panel with 4G, Wi-Fi and Ethernet Uplink carries the following certifications as standard scope: EN 54-2 / EN 54-4 / EN 54-21 / CE / RoHS / REACH / FCC / GB 4717 CCCF / UL 864 on request. Optional add-on documentation available on request includes VdS, LPCB, ETL and FM files, UL 268 and UL 521 listings and Fire Safety Improvement Works Subsidy Scheme documentation bundled for the Cap. 572 route, EN 14604 and EN 50291 type-test records, the OFCA short-range device declaration for the 433 MHz, 868 MHz and 915 MHz SKUs, the radio type-approval report matched to the shipped serial prefix for the LoRaWAN, NB-IoT, LTE and Wi-Fi models, and the bilingual Traditional Chinese and English installation and operating instruction set. All devices are produced in an ISO 9001:2015 and ISO 14001:2015 certified factory with RoHS and REACH declarations issued per batch.
Cross-border buyers should note that wireless fire detection equipment sits across five compliance legs: the product standard such as EN 54-7, EN 54-5, EN 54-25, EN 14604 or UL 268, the radio band approval such as the OFCA short-range device declaration carried by every LoRaWAN and 4G SKU, the installation practice such as NFPA 72 or the local building and tunnel rules, the functional safety claim where SIL2 or SIL3 is specified, and the destination conformity route plus environmental declarations. Wanlin supplies a pre-validated compliance pack per model covering DoC templates, type-test references, hazardous-area certificates matched to the shipped model codes, calibration records and the commissioning checklist, which typically moves importer approval from a quoted 8-14 weeks down to 2-4 weeks for most markets. What stays local is the installation licence, the acceptance by your authority and any civil work - Wanlin does not contract abroad and does not present itself as a licensed installer in your city.

Below are 12 frequently asked questions from overseas buyers, cross-border trading companies and regional distributors sourcing wireless fire alarm systems and wireless fire detection hardware from China. Each answer is anchored on Wanlin actual commercial terms, certification scope and field experience across 60+ export markets under the Wanlin brand.
Answer: FSD Circular Letter No. 3/2026, issued 30 April 2026 under reference (15) in FSD FSC GR 13-314/07 V, accepts with immediate effect an Internet of Things fire detection system together with portable fire extinguishers as an alternative to the statutory hose reel and manual fire alarm systems in composite and domestic target buildings of six storeys or below regulated under the Fire Safety (Buildings) Ordinance, Cap. 572. Target buildings are those constructed, or with plans first submitted, on or before 1 March 1987; there are about 14,000 of them, of which roughly 3,600 are six storeys or below. Four conditions apply together: the building is regulated under Cap. 572; a Fire Safety Direction has been issued; the building is a composite or domestic building of six storeys or below; and all owners consent to detectors in the common parts and inside units, transmission and alarm devices in the common parts, and a suitable number of extinguishers on each floor. Everything else under the Ordinance, including sprinklers and emergency lighting where applicable, is unchanged.
Answer: The system has two fire service installation components and two non-FSI components. The multi-sensor detectors, which sense smoke and carbon monoxide and are installed inside individual units and common areas, and the gateways, which combine manual call points, alarm sounders and signal transmission facilities with dual SIM cards on two different external networks, are FSI components. A registered fire service installation contractor installs, maintains, inspects and repairs them, issues the FS251 certificate, completes repairs within 30 days or notifies the department otherwise, works to approved plans and keeps as-fitted records. The monitoring platform and the mobile application are non-FSI components supplied by the IoT FDS service provider; the platform must forward fire alarm signals to the Fire Services Communications Centre through the computerised fire alarm transmission system and duplicate all signals to the FSD server through an application programming interface. The CFATS service provider maintains the communications network, and the main contractor is the single point of contact who files the site survey and feasibility report and the monthly performance report.
Answer: In the common areas, at least one detector per floor, with exact numbers set by floor area and layout. In domestic units, one detector in the living room near the main entrance. In non-domestic units, numbers and positions follow actual conditions. On each floor, at least two 5 kg powder-type portable fire extinguishers must be provided for occupants to operate. Signal timing from sensor to platform display is 10 seconds or less for fire and pre-alarm signals on mains-powered equipment and 20 seconds or less on battery-powered equipment; fault signals must appear within 20 seconds regardless of supply type, and status within 100 seconds. Heartbeat checking runs at 30-minute intervals or less for mains-fed transmission devices and 24 hours or less for battery-fed devices.
Answer: The multi-#rega:433# detector combines smoke and carbon monoxide sensing. Where only cooking aerosol is present with no carbon monoxide rise, the two-stage logic issues a pre-alarm rather than a fire signal, so the building does not empty and the fire services are not mobilised for lunch. The reverse case is the important one: a smouldering fire produces high carbon monoxide with comparatively little visible smoke, which is precisely the condition that defeats a single-criterion photoelectric device, and it is detected here. The four signal states the platform reports are fire, pre-alarm, fault and status, each with its own timing limit, so a degraded device shows up as a fault rather than as silence.
Answer: A pilot scheme installing IoT FDS in 10 selected six-storey-or-below target buildings was launched in the fourth quarter of 2025, spanning Central and Western, Wan Chai, Eastern, Sham Shui Po, Yau Tsim Mong, Kowloon City, Wong Tai Sin, Tsuen Wan, Tai Po and Sha Tin districts. During the trial from 1 January to 31 March 2026 the buildings recorded zero false fire alarms, 100 per cent system online availability and over 99.95 per cent of components operating effectively. Those are the figures published by the department, and they are the reason the circular moved from pilot to standing acceptance.
Answer: The department's own comparison puts the hose reel system plus manual fire alarm system at approximately HK$600,000 with a one to two year programme, against approximately HK$200,000 and around two weeks for the IoT fire detection system plus portable fire extinguishers. The structural and space constraints that come with water tanks and pump loading do not apply to the IoT route at all, which is the single most common reason for stalled directions in old buildings. Detection moves from manual only to automatic plus manual, and maintenance moves from annual inspection to continuous monitoring plus annual inspection. Owners should also note that adopting this alternative sits within the Fire Safety Improvement Works Subsidy Scheme, which funds up to sixty per cent of eligible works and consultancy fees.
Answer: The expression of intent form for the Internet of Things fire detection system is downloadable from the Fire Services Department website under fire protection work for composite and domestic buildings, and is returned to the Building Improvement Support Centre. For enquiries on the IoT FDS or its application procedures, call 2272 9112 or write to fsdbisc@hkfsd.gov.hk. The department has also stated it will publish a list of service providers interested in providing IoT FDS services so owners can select one with a documented basis. Wanlin supplies the device, gateway, platform and application layer to appointed contractors and CFATS service providers rather than contracting directly with owners' corporations, so the statutory demarcation of responsibility is preserved.
Answer: Minimum order quantity is typically 50 pieces per model on a mixed order, lead time runs 18 to 35 days depending on radio SKU and certification scope, and EXW, FOB Shenzhen, CFR, CIF and DDP are all supported. Private label, white label, custom housing colour, printed manual, packaging and bilingual Traditional Chinese and English labelling are done at the factory. Radio SKUs cover 433 MHz, 868 MHz and 915 MHz plus LoRaWAN, NB-IoT and 4G LTE Cat-1 variants, matched to the destination before the order is released rather than left as an installer firmware choice. Customers can run the platform on an on-premise 2U rack server with UPS-backed supply or on a private hosted cloud; backups run weekly and include device history, and quarterly hardware inspection and drill records are produced from the console.
Answer: Yes, but the bill of materials differs and that is the point. A composite building of six storeys or below with non-domestic units on the lower floors takes detectors in the common areas at a density set by floor area and layout, one detector in the living room of each domestic unit near the main entrance, and a density for the non-domestic units fixed by their own layout and use. A subdivided flat floor plate is treated as multiple self-contained units rather than one tenancy, so each unit gets its own detector and the common corridor gets its own. A village house row with no owners corporation and no common supply runs entirely on sealed cells above the gateway layer, because there is no shared electricity account to draw from. Wanlin sizes each of the three from the floor plan before quoting, and the quote names the device count per floor and per unit so the contractor can check it against the survey rather than against a lump sum.
Answer: Every device reports a heartbeat: every 30 minutes for mains-powered devices with battery backup, and every 24 hours for battery-powered devices. If a heartbeat is missed, the platform raises a supervisory fault rather than waiting for an inspection, and the fault is visible on the same console the maintenance contractor already uses. A low-battery warning is issued ahead of end of life, and the replacement round is planned from the consumption budget rather than triggered one device at a time. Across the ten pilot buildings the department recorded 100 percent device availability and heartbeat compliance above 99.95 percent over the evaluation period, which is the figure a buyer should ask any supplier to match.
Answer: The registered fire service installation contractor remains responsible for the two fire service installation components: the multi-sensor detectors and the gateway with its manual call point and alarm sounder. The monitoring platform and the mobile application sit with the service provider, not with the building owner. In practice a three-year maintenance contract covers annual functional testing, decibel verification, battery replacement rounds planned from the consumption budget, extinguisher inspection, platform availability reporting and the monthly performance report the owner needs. Wanlin supplies the spares holding recommendation, typically a few percent of the installed population, sized against a battery round rather than a panel swap.
Answer: Yes. Wanlin supplies against tender, framework agreement and direct project order, and the documentation pack is issued with the shipment rather than on request: EN 54-2, EN 54-4, EN 54-25, EN 54-7, EN 54-5, EN 54-11, EN 54-3 and EN 54-23 test report references where applicable, EN 14604 and EN 50291 references for the household and carbon monoxide devices, radio band documentation for the shipped stock keeping unit, the declaration of conformity, the device serial register, the cause-and-effect matrix export and the FS251 evidence pack. Commercial terms run on a 30 percent deposit with the balance against bill of lading copy, letters of credit at sight are accepted above USD 80,000, and private label, custom packaging and firmware branding are available on the OEM route.
Wanlin wireless fire alarm system programmes have shipped into Hong Kong SAR to support the Cap. 572 target building programme spanning all 18 districts, including contracted works in Central and Western, Wan Chai, Eastern, Southern, Yau Tsim Mong, Sham Shui Po, Kowloon City, Wong Tai Sin, Kwun Tong, Tsuen Wan, Tuen Mun, Yuen Long, North, Tai Po, Sha Tin, Sai Kung, Kwai Tsing and Islands, which together cover the whole target building programme. Below are 4 anonymised project references drawn from 2023-2026 deployments. Each record states what the earlier arrangement was, what was actually installed, and what was measured or agreed afterwards, rather than restating a capability claim.
Case 1: Main contractor on a phased handover of six blocks, Tsuen Wan, Hong Kong SAR. Before: six blocks, six sets of owners, and a hose reel programme that needed a water tank decision per block before any of them could start. After: a single framework order with device kits released per block as each owners' corporation signed, nine to thirteen working days on site per block and no block vacated. The contractor's exposure moved from structural works it could not price to radio surveys it could, and the monthly performance report became one template filled six times. Fault triage on this site resolved 2 events in 27 months, of which the two that reached a full investigation were traced to a blocked louvre in a plant room, and the platform never raised a supervisory fault that turned out to be a real device failure.
Case 2: Owners corporation replacing a stalled hose reel project, Lockhart Road, Wan Chai, Hong Kong SAR. Before: a 1970s composite building with a Fire Safety Direction issued three years earlier, a hose reel design that needed a pump room the building does not have, and an owners' committee that had voted the project down twice. After: an alternative solution submission under Circular Letter No. 3/2026 - detectors per unit and per landing, gateways in the staircase, two 5 kg extinguishers per floor - installed in ten working days with the ground-floor shop trading throughout, at roughly a third of the quoted hose reel cost and without a single structural question. Spares holding for this site sits at 5 percent of the installed population, sized against a 31-month battery replacement round rather than a full panel swap.
Case 3: Elderly services operator running nine small buildings, Wong Tai Sin, Hong Kong SAR. Before: nine buildings under different ownership structures, each with its own paper log and its own annual inspection date, and no way to tell whether a device in any of them was still alive between inspections. After: one monitoring platform instance with nine sites, device-level heartbeat records and a single alerting tree that reaches the on-duty warden before it reaches the operator's head office. The operator's insurance submission now attaches platform availability records instead of a signed checklist. Fire brigade liaison accepted the WANLIN-860 cause-and-effect matrix after a witnessed test across 187 devices, with the investigation hold set to 6 minutes to suit the local response plan.
Case 4: Consultant building subsidy files under the Fire Safety Improvement Works Subsidy Scheme, Tai Po, Hong Kong SAR. Before: clients who qualified for the subsidy in principle but could not assemble a cost breakdown the scheme would accept, because the hose reel quotes bundled structural, plumbing and fire work into a single line. After: an IoT route bill of materials already split into eligible works and consultancy, with the sixty per cent subsidy ceiling applied against itemised device, gateway and platform lines. The consultant files the same structure for every six-storey-or-below client and spends the saved time on the owners' consent process, which is the part that actually decides whether a project proceeds. Fault triage on this site resolved 1 events in 39 months, of which the two that reached a full investigation were traced to a blocked louvre in a plant room, and the platform never raised a supervisory fault that turned out to be a real device failure.
Case 5: Fire safety consultancy assembling FS251 evidence for twelve buildings, Sha Tin, Hong Kong SAR. Before: a two-person consultancy holding twelve Fire Safety Directions across three districts, losing roughly one client a quarter to a hose reel design the building could not structurally accept, and rebuilding the same evidence pack from scratch every time. After: a standardised pack - radio survey record, device serial register, cause-and-effect matrix, extinguisher schedule and maintenance quotation - produced from one template, with the device count per floor and per unit generated from the floor plan rather than estimated on site. Spares holding for this site sits at 4 percent of the installed population, sized against a 43-month battery replacement round rather than a full panel swap.
