    Orbis Intrinsically Safe (IS) Multisensor Detector

    The Orbis I.S. Multi-sensor Detector benefits from the same false alarm reduction technology as the optical detector. It is a thermally enhanced smoke detector and so will not give an alarm from heat alone.

    Key Features

    • Reduces false alarms.
    • Sensitive to fast burning, flaming fires.
    • Improved sensitivity to black smoke.
    • Compensation for slow changes in sensitivity.
    • Algorithms for reliability of alarm.
