The FEAHE2000 is an analogue addressable rate of rise heat detector. It will respond with a value of 75 if the detector is triggered by a rate of rise alarm (that is a fast increase in temperature over a set period of time). The detector also responds to a fixed temperature of 57°C and will return a value of 95 if the detector is triggered by this condition.
The FEAHHE2000 is an analogue addressable fixed heat detector. It will respond with a value of 95 if the detector is triggered through a fixed heat alarm of 90°C.
