Advanced MultiCriteria Fire Detector

The 2251-COPTIR plug-in fire detector combines four separate sensing elements in one unit: photoelectric chamber senses airborne particulate for smoke detection, electrochemical cell technology monitors carbon monoxide (CO) produced by smoldering fires, infrared (IR) sensing measures ambient light levels and flame signatures, and thermal detection monitors temperature.

The integration of continual monitoring for all four major elements of a fire has enabled System Sensor to create a detector that responds more quickly to an actual fire with the highest immunity to nuisances. This advanced multi-criteria detector normally operates at a high immunity level and changes to become very sensitive to fires as soon as fire characteristics are sensed. In this way, nuisances are monitored and ignored, reducing false alarms.
