Fyreye MKII Conventional Rate of Rise and Fixed Heat Detector (MKII-HR)


Fyreye MKII Conventional Rate of Rise and Fixed Heat Detector (MKII-HR):

Fyreye MKII Conventional RoR & Fixed Heat Detector The Fyreye MKII Rate of Rise heat detectors (MKII-HR) uses a thermistor arrangement to sense a quick rise in temperature and also a final threshold temperature of 57°C. The detector will work with most modern fire alarm control panels, and comes supplied with a locking grub screw to prevent unauthorised head removal.

   

    

The Fyreye MkII optical smoke detectors use a pulsing IR LED & photodiode to detect IR scatter caused by smoke entering the chamber.

The detector is particularly suitable for detecting optically dense smoke, involving materials such as soft furnishings, PVC, plastic, foam and all similar materials which produce small visible particles (0.5 to 10μm).

The Fyreye Rate of Rise heat detectors (MKII-HR) 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
