Global Fire Equipment GFE-ADII GFE Addressable Stand-Alone Loop Isolator
Global Fire Equipment GFE-ADII GFE Addressable Stand-Alone Loop IsolatorThe GFE-ADII 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-ADII 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.
