Description
System Sensor 22051TLE-26 Photoelectric, Thermal & Infra-Red Detector with Isolator
The 22051TLE multi-criteria multi-sensor Photo Thermal Infra-Red detector (PTIR) is the environmentally friendly alternative to the ionisation detector, a technology that is over sixty years old. The detector offers comparable speed of response to the ionisations technology for a fast flaming fire and is less susceptible to false alarms. It can be deployed with confidence in locations where the main risk is from fast-developing flaming fires.
The integration of continual monitoring for all three major elements of a fire enables the 22051TLE respond far more quickly to an actual fire and has the highest immunity to nuisance. The sensing elements of the 22051TLE are panel controllable so the sensitivity thresholds of each element can be changed by the panel offering the ability to customise the device for the changing use of the area it is protecting.
