The GFE-AD-ISO is a standalone negative switching loop isolator, designed to isolate short circuits on the addressable detection loop of a Global Fire Equipment Juno-Net or Junior control panel.
Up to 32 detection devices may be connected between two isolators as per EN54.
The GFE-AD-ISO is loop powered and polarity sensitive and care must be taken to follow the indications on the PCB. Also as two LEDs are fitted to facilitate “Loop in” and “Loop out” identification a consistent approach should be taken to wiring the isolator in this respect.
