Operation
Automatically opens circuit when the line voltage drops below four volts. Fault Isola-
tor Modules should be spaced between groups of addressable devices (maximum
25, see notes on page 1) in a loop to protect the rest of the loop. If a short occurs
between any two isolators, then both isolators immediately switch to an open circuit
state and isolate the groups of sensors between them. The remaining units on the
loop continue to fully operate.
In Style 4 loops, the SS-LI is generally used at each T-tap branch, to limit the effect of
short circuits on a branch to the devices on that branch. The LED indicator is on
continuously during a short circuit condition.
The SS-LI Fault Isolator Module automatically restores the shorted portion of the
communications loop to normal condition when the short circuit condition is removed.
