S200 Addressable Thermal Detectors

Thermal detectors 52051E/EI, 52051HTE/HTEI, 52051RE/REI, are part of S200 range are analogue addressable sensors employing low mass thermistors and microprocessor technology for fast response and linear/raising temperature sensing.

The 52051E/EI and 52051HTE/HTEI detectors’ 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/REI 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°C, a fixed 78°C unit or a 58°C with rate of rise device.
