Heat Detector
Fixed temperature (57°C / 90°C) and rate-of-rise heat detectors for kitchens, boiler rooms, and dusty factories where smoke detectors would give false alarms. Highly reliable, no false alarms from cooking fumes.
Activation Temp.
57°C (standard) / 90°C (high)
ROR Trigger Rate
> 6.7°C per minute
Operating Voltage
9–30V DC
Heat Detector
IS:11360 / EN 54-5
Working Principle
How It Works
A fixed-temperature heat detector contains a fusible alloy element or bimetallic strip that triggers at a pre-set temperature (57°C or 90°C). Rate-of-rise detectors continuously monitor how quickly temperature increases — triggering an alarm if the rise exceeds approximately 6.7°C per minute, even before the absolute temperature threshold is reached. Both types are mechanically simple, highly robust, and require minimal maintenance.

Maintenance & AMC Tips
Test annually using a heat gun or approved test lamp (never open flame)
Inspect housing for dust, grease, and condensation buildup
Verify wiring terminals are secure and corrosion-free
Replace unit immediately if subjected to a real fire event
Check compatibility with panel firmware after any panel upgrade
Legal & Compliance Requirement
Heat detectors are the correct solution wherever smoke detectors would generate nuisance false alarms — commercial kitchens, boiler rooms, paint booths, laundries, and dusty manufacturing areas. NBC 2016 and fire department inspection guidelines specifically require heat detectors in these high-temperature or contaminated environments.
