The 0ExiaIICT4 X explosion-proof marking makes it possible to use the detector in the explosion-hazardous areas of enclosed facilities and outdoor installations. Explosion-hazardous areas class is “0”, ”1” and ”2”
An intrinsically safe circuit is required to connect an intrinsically safe detector.
The detector is connected to an explosion-proof Fire Alarm Control Unit with an intrinsically safe outlet or to a general industrial Fire Alarm Control Unit via an I.S. barrier. I.S. barriers recommended by the manufacturer:
Spectron-IB-01 - 12 V/500 mA for a non-addressable detector with 4-wire connection;
Spectron-IB-02 - 24 V/100 mA for a non-addressable detector with 2-wire connection to Fire Alarm Control Unit alarm detection circuit;
