Zeta Alarm Systems MKII-AOP optical smoke detector

Zeta Alarm Systems MKII-AOP is an optical smoke detector. This Fyreye MkII optical smoke detector uses a pulsing IR LED & photodiode to detect IR scatter caused by smoke entering the chamber. The detector works with most modern fire alarm control panels and comes supplied with a locking grub screw to prevent unauthorised head removal. It is designed to meet EN54 requirement and has a single thermistor arrangement that gives an alarm at a temperature of 90°C.
