Zeta Fyreye MkII Conventional Heat Detectors MKII-HF/CS90

Zeta Fyreye MkII Conventional Heat Detectors MKII-HF/CS90

The Fyreye Rate of Rise heat detectors (MKII-HF)
use 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-HF) 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.

Zeta Fyreye MKII Conventional Heat Fixed Detector MKII-HF detect heat at a temperature of 90 degree. At this stage the Alarm is triggered
