XP95-LI Description Line Isolator CS-2051ph1.wmf The Gamewell-FCI analog addressable systems can be wired as Style 7 (Class A) closed-loop systems. These systems 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. XP95-LI Features 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). • Compatible with the Gamewell-FCI 600 Series analog addressable fire alarm panels. • Protects the integrity of the initiating loop should a short-circuit fault occur. • Monitors and controls up to 50 points per circuit. • Mounts in its own unique base. • Up to 50 circuit isolators can be supported on a single SLC. • Low-profile styling. • Integral yellow LED. Isolators are polarity sensitive and the positive DC supply must be connected to terminal “L2 IN/OUT” and the negative DC supply to terminal “L1 IN/OUT”.
