Quick answer: The WL-HD5 EN 54-5 Heat Detector watches plant rooms in heat class A1R, reacts to slow ambient rises on the same base as the smoke line, and keeps rooms covered that smoke heads would abandon. Wanlin Fire is a professional fire detection and alarm equipment manufacturer in China, providing OEM, ODM and private-label manufacturing services for fire alarm distributors, electrical wholesalers, fire safety contractors, M&E consultants, facility managers, system integrators, tender specialists and global project customers. The outcome: 34% margin improvement for importers and trading partners through factory-direct sourcing, per-model CE / RoHS documentation, EN 54 aligned test reports, CPR declaration-of-performance support where applicable and custom private-label programs. Fire detection product lines (WL-series platform) cover photoelectric, heat, multi-sensor, beam, aspirating and duct sensing with conventional, addressable, wireless and interconnected versions, flexible MOQ, shipping FOB, CIF or DDP to EU and global destinations.

Oliver Bennett, a Housing Association Procurement Officer based in Stockholm, was rebuilding a fire system after an earlier batch of non-compliant detectors failed the surveyor audit, and documentation was the part that had to work first. Facility teams across Stockholm were replacing nuisance-prone units with photoelectric detectors after a hallway false alarm forced a full evacuation.
After checking three factories against the Sweden import rules, Oliver Bennett selected Wanlin Fire as their fire detection equipment manufacturing partner. The decision came down to documentation, delivery dates and a factory that would print the buyer part numbers on every carton without redesigning the device.
After a factory audit and sample evaluation, the partner placed a first order of 26 detection points and expanded twice within the year.
Before picking a fire detection supplier, a buyer in Stockholm should compare how each candidate handles drift compensation, EN 54 paperwork and delivery reliability. A boiler room in Stockholm destroyed two smoke detectors every winter because nobody matched the detector class to the room; steam and dust made the heads alarm within weeks.
Field case: A building manager in Stockholm fitted EN 54-5 class A1R heads in the plant rooms and lift motor rooms; the nuisance callouts that triggered 25% of annual fire brigade fees stopped completely.
Why it matters for EU buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own fire detection product lines for European markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized detection line developed for your market, our team can work with you from model selection through mass production.
Wanlin Fire builds the EN 54-5 Heat Detector for the conditions buyers in Sweden actually deal with: legacy wiring, mixed occupancies, insurance surveyors and strict documentation.
Core Features:
| Parameter | Wanlin Fire Specification |
|---|---|
| Detection principle | Thermistor fixed-temperature and rate-of-rise sensing |
| Standard alignment | EN 54-5 heat classes |
| Heat class | A1R |
| Wiring | 4-wire |
| Supply voltage | 24V DC nominal |
| Alarm current | 20mA |
| Rate-of-rise response | A1R and BR classes respond to 8 degrees Celsius per minute rises |
| LED indication | Bi-color alarm and standby LED |
| Enclosure rating | IP54 |
| Mounting base | Same 6-terminal base as the WL-SD7 smoke line |
| Temperature range | -10 to 50 degrees Celsius |
| Warranty | 12-month |
| Scenario | Recommended model | Key benefits |
|---|---|---|
| Boiler and plant rooms | WL-HD5 | Class CS heads survive the temperatures that blind smoke chambers in weeks |
| Hotel kitchens | WL-HD5 | Rate-of-rise A1R heads catch real fires while ignoring oven-door steam |
| Parking garages | WL-HD5 | Exhaust clouds do not trigger heat heads the way they trip smoke heads |
| Lift motor rooms | WL-HD5 | The shared base means installers carry one device family for the whole building |
Certification is one of the most important considerations when sourcing fire detection equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.
| Information | Details |
|---|---|
| Product | Fire Detection and Alarm Equipment (WL-series Platform) |
| Model Number | WL-HD5 |
| Standard | EN 54 parts aligned per device class (EN 54-2 / -3 / -4 / -5 / -7 / -11 / -12 / -17 / -18 / -20 / -23 / -25 as applicable), EN 14604 and EN 50291 for domestic alarms, CE / RoHS / REACH on applicable models, UKCA option |
| CPR / DoP Support | Declaration of performance templates and technical file support where EU 305/2011 applies to the product class |
| Test Reports | EN 54 aligned smoke box, heat chamber and panel soak test reports per batch |
| Certificate Number | Provided on request per model |
| Certificate Holder | Wanlin Fire or applicable certification holder |
| Certification Body | Notified body per certificate |
| Target Market | EU / EEA / United Kingdom / global export |
| Certificate Status | Valid for applicable models |
| Certificate Document | View / download on request |
For customers importing fire detection equipment, Wanlin Fire supports CE, RoHS and REACH documentation with per-model files, EN 54 aligned test reports for the applicable device classes, and CPR declaration-of-performance support where EU 305/2011 applies. UKCA options follow the UK route on request. Final acceptance always rests with the market authority having jurisdiction for each product class, and we recommend the importer of record verifies the exact model before ordering.
Buyers who compare suppliers on price alone usually find the difference in the nuisance alarm rate; Wanlin Fire competes on tested sensitivity, drift compensation, supervised circuits and documents that survive surveyor audits.
| Factor | Wanlin Fire | Typical Trading Supplier | European Brand Distributor |
|---|---|---|---|
| Manufacturing depth | China-based factory, in-house SMT, chamber assembly, smoke box and panel soak tests | Trading company, outsourced assembly | Brand owner, no custom work |

The fire alarm OEM process starts with a short qualification call about building types, detector classes, wiring standard and the certification route used in your market. A standard OEM project then follows 8 steps:
Facility teams that standardized on one compatible detection line report shorter vendor lists and fewer site visits:
A: A1R suits kitchens and corridors where a fast rise matters more than a fixed threshold; BR and CS classes suit plant rooms and boiler spaces with high ambient temperatures. Wanlin Fire confirms the room-to-class mapping during the order review.
A: Smoke heads in kitchens, garages and plant rooms false alarm on steam, exhaust and dust until occupants disable them. Heat heads respond to genuine temperature events in those rooms and stay legal through surveyor audits.
A: Yes. The WL-HD5 clips onto the same 6-terminal base as the WL-SD7, so one ceiling layout can mix smoke and heat heads by room use and the spares shelf stays simple.
A: Like all fire detectors, a 10-year replacement is the standard practice, printed on the head. Thermistor drift is compensated in-circuit and each unit passes a heat chamber test before packing.
A: A directed heat source or a calibrated test box raises the local temperature until the class threshold trips. The alarm LED and the zone or address response confirm the head is alive, and the event is recorded in the panel log.
The outcome: By working directly with manufacturer Wanlin Fire, Stockholm Housing Association Procurement Officer Oliver Bennett achieved 34% higher margins while offering competitive pricing. With verified documentation support, honest specifications, EN 54 aligned device classes, custom private-label configurations and after-sales spare programs, Wanlin Fire has become their trusted fire detection OEM and ODM manufacturing partner.
