XP95-LI
Description
The Gamewell-FCI analog addressable systems can be
wired as Style 7 (Class A) closed-loop systems. These sys-
tems can be interrogated from either end so that all devices
can remain in operation if an open circuit fault in the wiring
occurs. A short-circuit fault can potentially disable the
whole loop. By placing the Gamewell-FCI XP95-LI Line
Isolator modules along the loop, only the small section
between isolators will be affected by the short-circuit fault.
The XP95-LI line isolator mounts directly to a unique base
for ease of installation. The unique base will not accept any
other 600 Series XP95 products, eliminating the possibility
that any other XP95 Device could be installed in place of
an isolator.
Line Isolator
XP95-LI
Operation
The Gamewell-FCI XP95-LI line isolator uses a patented
technique to recognize a wiring short circuit by monitoring
a drop in voltage.
In standby operation, the isolator provides a two-way
power and data pathway with a low resistance of 0.4 ± 0.1
ohms in either direction. If the incoming or outgoing supply
voltage falls below 15 V ± 0.5 V, this is detected and the
line isolator from the remainder of the SLC isolates the
short circuit. The yellow LED on the isolator will then flash
at three-second intervals. The isolator continues to monitor
voltage, and when the short circuit is repaired the isolator
automatically reverts to its low-resistance condition.
The ideal number of isolators is determined by the system
layout with 50 isolator modules maximum on any signaling
line circuit (SLC).
Isolators are polarity sensitive and the positive DC supply
must be connected to terminal “L2 IN/OUT” and the nega-
tive DC supply to terminal “L1 IN/OUT”.

Standard Applications
The XP95-LI line isolator should be utilized any time the
integrity of the line is essential.The XP95-LI is typically
used at areas within a line that branch off in a unique direc-
tion, or to provide additional protection by isolating zone
monitoring devices.
