    The Fyreye MKII optical smoke detector (MKII-AOP) uses 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).

    Key Features

    • Designed to meet EN54 requirement.
    • Lockable to base to stop unauthorised removal.
    • Remote LED output.
    • 8 LEDs for improved, 360° visibility.
    • Compatible with all Fyreye MkII bases.
    • Addressed with dip switches or hand-held programmer.
