Product Details for Global Fire Addressable Stand-Alone Loop Isolator (GFE-ADII)
The Global Fire GFE-ADII (GFE-AD-ISO) is a standalone negative switching loop isolator designed to isolate short circuits on the addressable detection loop of all GFE addressable fire alarm control panels.
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 when wiring the isolator.
