Analogue Addressable Multi-Criteria Smoke Sensor

Analogue addressable multi-criteria smoke sensors are microprocessor controlled plug-in type sensors uses software algorithms to combine carbon monoxide, photo electric, thermal and infra-red sensing elements with addressable-analogue communications giving reliable fire detection whilst allowing the detectors to reject many common causes of nuisance alarm.

Multi-criteria smoke sensors are designed for open area protection and must only be connected to control panels that use a compatible proprietary analogue addressable communication protocol for monitoring and control. Two LEDs on each sensor light provide a local 360° visible sensor indication. The LEDs can be latched on by code command from the control panel for an alarm indication. They can also be unlatched to the normal condition by code command. Remote LED indicator capability is available as an optional accessory wired to the standard base terminals.
