TL;DR: The WANLIN-340 is our wireless heat detector, supplied in LoRaWAN, 4G LTE and 433 MHz versions for kitchens, plant rooms and dusty or wet rooms where a smoke chamber would keep going into alarm. Wanlin Fire is a wireless fire alarm system manufacturer and export supplier in China, covering wanlin-340 lorawan heat detector plus the wider wireless detection, alarm, control, monitoring and test equipment range for OEM, ODM and private label programs. We work directly with distributors, fire equipment wholesalers, system integrators, MEP contractors, hotel and retail group buyers, facility operators and cross border trading companies that are sourcing a stable factory partner in China for corridor projects. Net result: roughly 36% additional margin after the private label change through factory direct sourcing, per-model documentation, per-model test files and flexible MOQ with long-term partner stock programs. The comparison took 17 days, most of it spent waiting for documents that two of the four suppliers never sent.

The procurement team behind Andi Kurniawan in Amman shortlisted three factories on one condition: whoever answers the compliance clause in writing gets the order.
Distributors in Amman watched reseller margins compress, which reopened the private label conversation with Chinese factories.
The procurement committee in Amman built its own weighting sheet, and documentation scored as high as price. Andi Kurniawan signed off the first WANLIN-340 4G LTE Wireless Heat Detector order covering 22 sites in Jordan, and the specification sheet was rebuilt around the reference standards and the radio plan rather than around a brand name.
The technical review lasted 17 days and included a dust chamber trial in one plant room that nobody had planned for. In an Amman mall the technical room and the public concourse need different detection, and one specification sheet that ignores that difference is the reason two of the last three submittals came back.
Three field reports from Amman describe the same root cause, and none of them was fixed by swapping brands.
A generator hall at an industrial site near Amman runs hot and dusty, and the optical heads in the corridor outside kept reporting contamination.
Field case: A cold store operator near Amman moved the loading dock onto sealed heat detection and stopped the seasonal contamination replacements.
Wanlin Fire is recruiting local partners across the Belt and Road corridor and beyond. Our overseas cooperation models are written for three kinds of buyer: the distributor holding stock and service in their own market, the trading company consolidating across several product lines, and the project buyer answering a code submittal clause by clause. Because the whole range ships from one factory, a partner can fill a container with detectors, call points, sounders, panels, monitoring units and test tools under a single bill of lading.
Partners across Southeast Asia, South Asia, Central Asia, the Middle East, Africa, Europe and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with samples and move to container volume once their own market testing is done.
Every unit in the line shares a service philosophy: respond early, nuisance rarely, and stay maintainable across a full replacement cycle. The WANLIN-340 is our wireless heat detector, supplied in LoRaWAN, 4G LTE and 433 MHz versions for kitchens, plant rooms and dusty or wet rooms where a smoke chamber would keep going into alarm.
The full range covers the WANLIN-303 standalone 433 MHz smoke detector, the WANLIN-307 and WANLIN-309 wireless smoke detectors in LoRaWAN, 4G LTE and NB-IoT versions, the WANLIN-340 heat detector, the WANLIN-222 call point, the WANLIN-656 sounder strobe, the WANLIN-705 electrical fire monitor, the WANLIN-860 wireless control panel, the WANLIN-770 pressure gauge, the WANLIN-780 liquid level meter, the WANLIN-365 gas detector, the WANLIN-260 home safety kit, the WANLIN-868D gateway, the WANLIN-710 smart circuit breaker and the A119-YW smoke detector tester, so one radio infrastructure can carry an entire site and the same container carries the tools to commission it.

| Warehouse and cold store loading docks | WANLIN-340 | Works where condensation and dust would contaminate an optical chamber |
| Workshops and vehicle maintenance bays | WANLIN-340 | Exhaust and metal dust do not produce the nuisance alarms a smoke head would raise |
Communication choice is the decision that decides whether a wireless scheme survives commissioning. Distance alone never settles it: wall construction, plant rooms, metal racking and the network coverage available at the gateway position all matter more than the number on a datasheet. Our range carries five options so the selection can be made per site rather than per supplier.
Radio behaviour is treated as a production step rather than a promise. Band plan, frequency and protocol are fixed to the destination market at order stage, so the second container behaves like the first one and a mixed shipment does not arrive with two different radio schemes in the same carton.
Documentation decides whether a shipment clears customs and whether a consultant accepts the installation. Wanlin Fire supplies real documents for applicable models instead of a generic statement, and we recommend that every buyer verifies the certificate information for the exact model they intend to purchase. Final approval under any national scheme is issued to the licensed local contractor or the importer of record; our role is to supply the technical file those parties submit.

Every export kit ships with the documentation set for the destination: declarations per model, construction papers where the device class applies, radio compliance files for the band plan in use, and labelling in the language the market expects. Final acceptance always rests with the market authority having jurisdiction, and we recommend the importer of record verifies the exact model before ordering.
Importers who have been burned before tend to rank their suppliers on evidence rather than claims.
Corridor projects add their own requirements to that list. Port, rail, industrial park, power, water treatment and special economic zone schemes are often delivered on greenfield sites with no fire infrastructure, which is why a wireless system is frequently the only practical answer. Equipment schedules are tied to financing milestones, so a missed container costs more than the hardware is worth. Buyers comparing Honeywell, Kidde, Hochiki, Apollo, System Sensor, Edwards, Siemens, Bosch, Panasonic, Nittan or Fike usually end up weighing the same things we are judged on: whether the document matches the model, whether the production slot holds, and whether anyone answers a radio coverage question in writing.

The process below is the one our partner accounts run every quarter, written as it actually happens. A standard OEM project then follows 8 steps:
Feedback collected after the first full year of each partnership, with names shortened for privacy.
A: Heat detection is chosen where the normal environment would keep a smoke chamber in alarm: kitchens, generator rooms, workshops, dusty stores and areas with heavy exhaust. The trade off is response time, because a heat detector reacts later than a smoke detector on a smouldering fire, so it is normally applied to specific rooms rather than to the whole building.
A: Yes. The WANLIN-340 reports over LoRaWAN, 4G LTE or 433 MHz depending on the version ordered, so it sits on the same gateway as the smoke detectors instead of requiring its own panel.
A: The fixed temperature threshold and the rate of rise behaviour are stated on the model datasheet for the version you order. We do not quote a threshold here because the correct figure depends on the room duty, and the site conditions should be reviewed before the specification is frozen.
A: The sealed head is the reason it is specified in those rooms. Even so, we recommend a siting review so the head is not placed where airborne dust settles on it, and a cleaning interval that matches the plant routine.
A: Send the room schedule and the wireless protocol you intend to use. We will return a model split covering smoke, heat, call points and sounders on one gateway, with samples first and production orders quoted per model and configuration.
Net result: By working directly with manufacturer Wanlin Fire, Amman Retail Chain Loss Prevention Manager Andi Kurniawan gained 36% margin headroom while keeping competitive installed pricing. With verified per-model documentation, honest specifications, EN 54-5 aligned construction on applicable models, CE and RoHS documentation, LoRaWAN, 4G LTE and 433 MHz radio compliance per destination band, local code submittal support with per-model technical files, national registration support for the importer of record, a communication option matched to the site, private label branding, a radio plan stated in writing and after-sales spare programs, Wanlin Fire became their long-term wireless fire alarm system supply partner in Jordan. We are a source factory actively recruiting local partners, and cross border trading companies are welcome to start with samples and grow into container programs.
