Headline: The WLM-8300 fuses dual-wavelength optical smoke sensing and 54C fixed-temperature sensing signals in one head, runs on a 10-year rated battery, and reports confirmed events over LoRaWAN so operators act on real fires, not steam. Wanlin Fire is a LoRaWAN fire alarm manufacturer in Shenzhen, China, running OEM, ODM and private-label programs for fire alarm distributors, life-safety importers, fire detection wholesalers, security and fire trading companies, system integrators, smart building providers, facility management buyers, property developers, hotel chains, retail chains, warehouse operators, schools, hospitals, energy storage projects and fire safety contractors. The number that matters: keeps 30-40 percent more margin for importers who source factory-direct, with per-model EN54 / CE / FCC / RoHS / UKCA documentation, LoRaWAN band compliance files, cell specification sheets and flexible OEM and private-label programs. The WL-series line covers LoRaWAN fire alarm gateways with Ethernet, WiFi and 4G backup uplinks, LoRa smoke detectors, 10-year battery smoke alarms, heat detectors, multi-sensor detectors, manual call points, sounder strobes, complete wireless fire alarm kits and retrofit systems, shipped FOB, CIF or DDP to global destinations.
Published by Wanlin Fire | Last updated: 2026-09-07 | Expertise: LoRaWAN fire alarm OEM manufacturing for global markets
A fire-safety buyer in Amsterdam walked into our stand at a regional safety expo holding a cable-quote that had just killed a retrofit budget. The maintenance team had spent the last two winters chasing low-battery chirps across hundreds of flats with no remote visibility.
After a two-week sample and range test, Daniel Carter selected Wanlin Fire as their LoRa fire alarm manufacturing partner. What settled it was the 10-year battery claim backed by a cell specification sheet and a low-battery event path, not a marketing sticker.
During commissioning, the team tested a real call point activation from the far stairwell and watched the event reach the dashboard in under two seconds.
Read these field reports before you choose a supplier; each one maps to a question you should ask in writing. A warehouse install places the gateway at the loading office, then finds the rack aisles with pallet steel create a shadow zone at the far end of the building.
Field case: a Dublin hotel retrofit mounted the gateway in the basement telecom room to hide cabling; floors three to six never joined reliably, and the authority inspection was postponed twice while the installer relocated antennas.
Why it matters for global buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own wireless fire alarm lines for global markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized wireless fire line developed for your market, our team can work with you from model selection through mass production.
The WLM-8300 is a EN54-25 aligned system practice device built around 15km line-of-sight LoRaWAN radio, a 10-year rated lithium cell and a housing that survives the environments where fire systems actually live.
Core Features:
| Parameter | Wanlin Fire Specification |

| Detection Principle | dual-wavelength optical smoke plus thermistor heat in one head |
| Compliance | EN54-29 aligned multi-sensor design |
| Battery | lithium cell rated up to 10 years with event reporting |
| Radio | LoRaWAN Class A, EU868 / US915 / AS923 / AU915 / IN865 options |
| Alarm Logic | algorithm fuses smoke and heat signals to cut false alarms |
| Alarm Output | 86dB sounder plus red LED with remote event push |
| Event Reporting | alarm, restore, low battery, fault, tamper and self-test |
| Drift Compensation | automatic dust and contamination compensation |
| Installation | surface or ceiling mount, tamper resistant |
| Operating Range | -10 to +55C, 10-95% RH non-condensing |
| Scenario | Recommended model | Key benefits |
|---|---|---|
| Hotel corridors with high ceilings | WLM-8300 | Fused smoke and heat logic catches slow smouldering fires early |
| Hospital wards where nuisance alarms matter | WLM-8300 | Signal fusion reduces false calls that interrupt patient care |
| Server rooms and electrical cupboards | WLM-8300 | Heat rise plus smoke confirms a real fire before clean-agent release |
| Museum and archive stores | WLM-8300 | Dual sensing gives earlier warning with fewer water-damage false events |
Certification is one of the most important considerations when sourcing wireless fire alarm 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.

For customers exporting wireless fire alarm systems, Wanlin Fire supports per-model certificate files and EN54-25 aligned system design documentation, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Devices ship with band-compliance settings for the declared market, and LoRaWAN conformance follows the published 1.0.4 specification. Final acceptance always rests with the authority having jurisdiction for each product class.
Importers compare wireless fire lines on device cost, but the projects that fail fail on documentation, battery honesty and open integration.
| Factor | Wanlin Fire | Typical Trading Company | Proprietary Wireless Brand |

| Customization | Private label, band variants, manuals and packaging from low MOQ | Stock SKUs only | No private label on hardware |
| Price (factory direct) | Competitive factory pricing with tiered discounts | Low price but quality and document risk | Brand markup of 2-4x |
| After-sales | Dedicated account manager, spare heads and gateways, firmware and re-commission support | No after-sales, high orphan risk | Limited, ticket-based support |
Wanlin Fire LoRa fire alarm services are suitable for: fire alarm distributors, life-safety importers, fire detection wholesalers, security and fire trading companies, system integrators, smart building providers, facility management buyers, property developers, hotel chain engineering teams, retail chain safety officers, warehouse and logistics operators, school and campus facilities teams, hospital engineering departments, energy storage project buyers, fire safety contractors and OEM ODM sourcing managers.
Every export project follows the same eight checkpoints, from band selection to the packing list. A standard LoRa fire alarm project then follows 8 steps:
Field partners across three continents report what changed after moving to an open LoRaWAN fire loop:
Q: What makes a multi-sensor detector better than single smoke?
A: It measures smoke and temperature together and applies fusion logic, so a genuine fire is confirmed faster while steam, dust and cooking events are rejected.
Q: Is it EN54-29 certified?
A: The design is EN54-29 aligned with documentation on applicable models; request the certificate for the exact variant before ordering.
Q: How does it report to the gateway?
A: It joins the LoRaWAN network with OTAA and publishes alarm, restore, fault and battery events over MQTT or HTTPS.
Q: Where should multi-sensor heads be used?
A: Corridors, wards, server rooms, archives and other zones where early warning matters but false alarms are expensive.
Q: What is the battery life?
A: Up to 10 years rated life with low-battery event reporting before the cell needs scheduled replacement.
The number that matters: By working directly with manufacturer Wanlin Fire, the OEM ODM Sourcing Manager team in Amsterdam reached 39% higher margins on its LoRa fire alarm line while keeping project pricing competitive. With verified certificate files, honest battery and range ratings, open LoRaWAN integration, flexible OEM customization and a factory that answers technical questions in hours, Wanlin Fire has become their trusted LoRaWAN fire alarm manufacturing partner.
