Zeta Alarm Systems FEAHE2000 addressable heat detector

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.
