Orbis Intrinsically Safe Conventional MultiSensor Detector

Orbis I.S. Multisensor Detector

The Orbis Intrinsically Safe MultiSensor 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.

The Orbis Intrinsically Safe MultiSensor Detector can be readily used instead of Optical Smoke Detectors but should be used as the detector of choice for areas where the fire risk is likely to include heat at an early stage in the development of the fire. This increased reliability of detection is combined with high immunity to false alarms.

  • 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.
