Case Study: Phitsanulok Government Project Contractor Sourcing Success
Orathai Pramong, a Government Project Contractor based in Phitsanulok, had watched a container of detectors stall at customs over incomplete papers. Two earlier sample batches had failed a basic functional spot test on arrival.
Following a three-week sample and testing round, Orathai Pramong selected Wanlin Fire as their fire alarm OEM manufacturing partner. Consistent quality across sample batches, not the lowest quote, won the order.
- In-house production: Wanlin Fire controls molding, assembly and detector calibration under one roof
- Compliance support: Tender-ready documentation prepared for the Thai market before shipment
- Export support: FOB / CIF Laem Chabang / DDP options with export documentation handled
The partner's own lab spot-tested the detectors against the quoted EN54 references before launch.
Problem Analysis & Field Report: Why Thailand Buyers Need Fixed Temperature Heat Detector
In the Thai project market, the gap between quoted specifications and delivered hardware is wider than most first-time importers expect. A laundry room in a hotel in Phitsanulok ran above 30°C every afternoon, which pushed a smoke detector into weekly false alarms.
Field case: a kitchen supervisor in Phitsanulok admitted during an insurance review that the smoke detector above the fryer had been taped over for 4 months; a fixed-temperature heat detector restored real coverage without the nuisance trips.
Why it matters for Thailand buyers:
- Heat detectors ignore steam, cooking plumes and lint dust that blind smoke detectors
- Rate-of-rise sensing still catches fast flaming fires before the fixed limit trips
- Shared bases with smoke detectors mean a position can be re-classed without rewiring
- Kitchens, laundries, garages and plant rooms all keep real coverage instead of taped-over detectors

Frequently Asked Questions
Q: Where should I use heat detectors instead of smoke detectors?
A: Thai kitchens, boiler rooms, laundries and covered parking all produce steam, dust or exhaust that causes smoke detector nuisance alarms. The TF-HT ignores those conditions and still responds to real heat events.
Q: What is rate-of-rise detection?
A: It alarms when temperature climbs faster than about 8°C per minute, catching fast flaming fires even before the fixed limit is reached, which suits timber and storage areas.
Q: Can it share a base with TF-SM smoke detectors?
A: Yes, both use the same twist-lock base, so a room can be re-classed from smoke to heat protection without rewiring.
Q: What response class fits Thailand?
A: Class A1 covers most interior rooms, while Class B suits hot roof spaces and plant rooms where normal ambient temperature runs higher.
Q: Do you support Thai import documentation?
A: Yes. TISI documentation support, EN54-5 architecture test references, HS code suggestions and Thai or English manuals are provided per order.
