multi sensor smoke heat detector

The revolutionary Series 200 Advanced range delivers a totally new detector platform that incorporates the new digital Series 200 Advanced Protocol. The new Protocol delivers more devices on the loop and gives greater control, configurability and device management whilst enabling the overall system to be optimised to the location and use of the building with far greater flexibility than ever before. The 22051TLE multi-criteria, multi-sensor Photo Thermal Infra Red (PTIR) detector is the environmentally friendly alternative to the ionisation detector, a technology that is now over sixty years old. The PTIR offers comparable speed of response to the inonisation 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. PTIR moves the goalposts in the fight against false alarms in the core detector space by delivering enhanced false alarm immunity. In addition to being an effective alternative to ionisation units, PTIR offers better performance over the alternative technologies of dual angle or dual wavelength optical detectors and photo-thermal detectors. 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 nuisances. Based upon the sensor signals, the program is dynamically changing sensor thresholds, changing sensor gain, changing time delays, changing combination, changing sampling rates, changing averaging rates and, if any sensor fails, changing sensitivity of the remaining sensors as well as indicating a fault condition. 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. The 22051TLE has two integral tri-colour LEDs that provide 360° local visual indication of the device status. The LEDs are programmable with static or blinking red, amber and green status indications available. All Series 200 Advanced detectors are environmentally friendly and meet the WEEE and RoHS legislative requirements, minimising end of life disposal costs, and are mechanically and electrically backwards compatible with existing Series 200 plus devices.
