SKU: 36f630b93813 Category: Brand:

Summary

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.

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.
