Zeta Fyreye MkII Conventional Smoke Detectors

10,200.00 excl. VAT


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.


  • Designed to meet EN54 requirement
  • Lockable to base to stop unauthorized removal
  • Remote LED output
  • Compatible with all Fyreye bases
