Description
Zeta Addressable Heat Detector
The Fyreye MKII Rate of Rise heat detector (MKII-AHR) uses a thermistor arrangement to
sense a quick rise in temperature and also a final threshold temperature of 57°C. The Fyreye
fixed heat detector (MKII-AHF) has a single thermistor arrangement that gives an alarm at
a temperature of 57°C, where the MKII-AHF/CS90 gives an alarm above 86°C.
