JTW-BD-ZR875H/T Heat Detector(90°) For Fire Alarm System

JTW-BD-ZR875H/T Heat Detector(90°) For Fire Alarm System

Product Introduction

A crucial component of marine fire safety systems, our Marine Fixed Temperature Heat Detector (90°C) is engineered to provide dependable and stable fire detection in environments where smoke detection may be impractical or unreliable. Designed specifically for areas prone to high ambient temperatures, steam, dust, or exhaust fumes — such as engine rooms, machinery spaces, galleys, and exhaust ducts — this detector activates the moment the surrounding temperature reaches its preset 90°C threshold.

Crafted from marine-grade corrosion-resistant materials, the detector withstands harsh maritime conditions including saltwater exposure, vibration, humidity, and temperature cycling. It meets stringent international standards, including SOLAS, IMO, and major classification societies (ABS, DNV, Lloyd’s Register, etc.), ensuring compliance and reliability for all vessel types.

The detector operates on a thermomechanical principle with a precision-calibrated fusible element, ensuring minimal false alarms and consistent performance over time. Its robust design requires no external power for activation and can be integrated into both conventional and addressable fire alarm systems, providing a clear signal to the central control panel.
