Fyreye MKII Addressable Rate of Rise Heat Detector (MKII-AHR)
|
The Fyreye Rate of Rise heat detectors (MKII- AHR) 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-AHF) has a single thermistor arrangement that gives an alarm at a temperature of 90°C. The detectors will work with most modern fire alarm control panels and comes supplied with a locking grub screw to prevent unauthorised head removal. The Fyreye Extra range of detectors has an extra LED to improve detector identification in an alarm condition. |

The Fyreye MkII optical smoke detectors usea pulsing IR LED & photodiode to detect IRscatter caused by smoke entering the chamber.The detector is particularly suitable for detectingoptically dense smoke, involving materials such as softfurnishings, PVC, plastic, foam and all similar materialswhich produce small visible particles (0.5 to 10μm).The detector will work with most modern fire alarmcontrol panels and comes supplied with a locking grubscrew to prevent unauthorised head removal.
