802177
The Esser 802177 is an IQ8Quad series intelligent addressable fixed heat detector with integrated isolator, specifically designed for higher temperature environments requiring EN 54-5 Class B response (fixed temperature trigger at +65°C).
It's functionally identical to the 802171 (Class A1S) but rated for increased operating temperatures up to +65°C, featuring decentralized intelligence, automatic self-test capability, CPU failure mode, and bi-color LED status indication.
