Heat detectors are essential fire detection devices that respond to increases in temperature, making them ideal for environments where smoke detectors may cause false alarms, such as kitchens, garages, attics, and industrial areas with dust or fumes. Our inventory includes rate-of-rise heat detectors, fixed-temperature models (135°F and other ratings), addressable photo\/thermal combination detectors, and explosion-proof models for hazardous locations.

The 2500 Open Loop Sensors use an external power source which will energize a built-in relay contact when water is detected. With this configuration the sensors are not fail safe. The relay output can be wired directly to any alarm panel or can be used to actuate an external device, i.e. transmitter, annunciator, etc.
