Analogue Rate of Rise Heat Detector 52051RE-26-IV

52051RE-26-IV - Analogue Rate of Rise Heat Detector with SYSTEM SENSOR Protocol

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, reconfigurability 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 52051RE uses the same thermistor and microprocessor technology to provide an alarm when the rate of rise in temperature exceeds 10°C/minute (typical) or if the temperature exceeds a threshold of 58°C (Response Class A1R). With the implementation of the Series 200 Advanced Protocol, any model can be software configured to be either a fixed 58©, a fixed 78© unit or a 58© with rate of rise device. For backwards compatibility and approval continuity, three separate versions continue to be available as separate part numbers.
The sensing elements of all three heat sensors are panel controllable through the Series 200 Advanced Protocol 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 22051TE has two integral tricolour 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.
