DESCRIPTION

The Fyreye Rate of Rise heat detectors (MKII-HFCS90) use a thermistor arrangement to sense a quick rise in
temperature and also a final threshold temperature of 90°C. The Fyreye fixed heat detector (MKII-HF/CS90) has a single thermistor arrangement that gives an alarm at a temperature of 90°C.
There are 4 types of mounting base available; standard or deep and with or without diode.
