The Model HLIM Loop Isolator Module from Siemens Industry, Inc. isolates short
circuits on FireFinder-XLS or FS-250 analog loops. By placing devices between HLIMs
during installation, a short in the wiring within that group is disconnected from the
rest of the loop. The remainder of the devices continue to operate. The HLIM oper-
ates in both Class A and Class B circuits.
A yellow LED flashes when a device detects a short circuit. The HLIM then isolates
that part of the loop. When the short is removed, the HLIM automatically restores the
loop to normal operation. The HLIM does not have a loop address and therefore does
not require address programming nor does it reduce the loop capacity below 252
devices.
Remove all system power before installation, first the battery and then the AC.

The HLIM is a polarity insensitive module. Refer to Figure 1 for the location of the
two input terminals, two output terminals and earth ground. Line 1 and Line 2 can be
either line of the loop.
