Overview
System Sensor Addressable Multi-Sensor Detectors provide a consolidated, reliable and high-quality detector platform with digital communication that is suitable for medium to large applications.
System Sensor Addressable Multi-Sensor Detectors combine thermal and photoelectric detection technology to provide advanced false alarm immunity and faster response to a wide range of fires. The two separate sensing elements are managed by embedded software which enables them to act as a single unit.
In areas where the normal daytime activities may potentially create unwanted alarms, these detectors can also be programmed to operate in “heat only” mode. System Sensor Addressable Multi-Sensor Detectors will automatically revert to full photo-thermal operation during unoccupied periods.
These detectors are housed in a modern, white enclosure and have a tri-colour LED offering red, green and amber colours providing 360° visibility.
