XP95-LI

Line Isolator

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.

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”.
