Short Circuit Isolator
This addressable device contains an integral short circuit isolator, which operates between the – IN terminal and the
– OUT terminal. The isolator operates in conjunction with Cooper Analogue Addressable Control Panels when a
low parallel resistance fault of typically 200? is present between the +VE and –VE of the loop wiring.
