DESCRIPTION 

 

Conventional heat detectors are suitable for connection to 2-wire and 4-wire Conventional fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept Conventinal type detectors1.
An electronic thermistor sensor provides sensitive rate-of-rise alarm operation, or fixed-temperature operation when the response threshold value is exceeded.
The  range of Conventional detectors provide fire detection and alarm system designers with a Standards-compliant, economical heat detector for property protection applications2 where smoke or multi-sensor detectors may not suitable due to environmental conditions.
