52051E-26 System Sensor Heat Detector

The revolutionary Series 200 Advanced range delivers a 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 52051E and 52051HTE are fixed temperature analogue addressable sensors employing low-mass thermistors and microprocessor technology for fast response and linear temperature sensing. Their linear response allows these sensors to be used to signal temperatures over the range of 58°C (Class A1S) to 78°C (Class BS). The 52051RE uses the same thermistor and microprocessor technology to provide an alarm when the rate of temperature rise 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 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.
