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