The 1-channel isolating transducer for fire and

smoke detectors IM33-FSD-EX/L is designed

especially for connection of conventional fire

and smoke detectors in the Ex-area.

They are supplied with energy. Actuation of

a smoke detector results in a current change

and the according signal is transmitted to the

non-Ex area. Several detectors can be connected to one circuit.

Input and output circuits are galvanically isolated from each other. The inputs of the isolating transducer are reverse polarity protected.

A current-to-ground error can be detected

safely via an external current-to-ground detector.
