ESSER 802271 Heat Detector ROR

ESSER 802271 ,Rate-of-rise heat detector includes a single thermistor to sense the air temperature around it. A fast semiconductor sensor guarantees reliable detection of fires with rapidly rising temperatures. An integrated fixed temperature function ensures the detection of fires with slowly rising temperatures. The device is ideal for sensing in environments that are dirty or smoky under normal conditions. It is unaffected by wind or atmospheric pressure, and boasts features like decentralised intelligence, automatic function self-test, CPU failure mode, alarm and operating data memory, alarm indicator, soft-addressing and operating indication. It is provided with an integrated isolator. A remote indicator can be connected.
