Esser 803371.EX IQ8 intrinsically safe optical smoke detector

IQ8 intrinsically safe optical smoke detector. Requires connection base 805590 not included

IQ8 intrinsically safe optical smoke detector, equipped with

individual microprocessor operating in intelligence systems

distributed, self-test function, CPU fault mode, data memory

alarm and operation, alarm indication, addressing by

software and indication of type of operation, when connected to a loop

esserbus or esserbus Plus.

The detector does not incorporate a loop short-circuit isolator, to allow its

operation in conventional mode, within zones intrinsically

safe, connected through the intrinsic safety barrier 764744 to zone

conventional transponder 808623.

Detector specification: EN54-7.

For its connection to the analog loop, it requires the 804744 barrier.

Accurate base 805590.
