COPTIR – 4 Sensor Addressable Multi-Criteria Detector

The 2251CTLE Multi-Criteria fire sensor combines independent carbon monoxide, photoelectric smoke, thermal heat, and infra-red light sensor working together in one device managed by highly sophisticated and responsive algorithms.

The 2251CTLE Multi-Criteria fire sensor combines 4 separate sensing elements to act as a single unit. CO sensing (using EC cell technology) for monitoring CO products from a smouldering fire, IR sensing for measuring ambient light levels and flame signatures, optical smoke and heat detection. The integration of continual monitoring for all four major elements of a fire has enabled the creation of a detector that responds far more quickly to an actual fire and has the highest immunity to nuisances.

Working philosophy: normally it operates at a high immunity level, changing to very sensitive to fires when fire characteristics are sensed.
