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 MA-1000 Control Panel when a low parallel resistance
fault of typically 200Ω is present between the +VE and –VE of the loop wiring.
