GENERAL DESCRIPTION

The Short Circuit Isolator Modules enable part of the
communications loop to continue operating when a short
circuit occurs on it. An LED indicator turns on during a
short circuit condition. The module will automatically
restore the entire communications loop to the normal
condition when the short circuit is removed.
