Orbis Intrinsically Safe (IS) Multisensor Detector
£61.67
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.
