The 4297 V-Plex Loop Isolation/Extender Module offers dual benefits for high security applications. As an isolation module, the 4297 allows installers to group selected zones on one loop. For example, fire and burglary zones may be grouped separately; essentially isolating one from another. This isolation feature prevents failure in one loop from compromising the integrity of any other loop. The 4297 Module also gives installers the flexibility to extend system-wide wiring capability, from approximately 4000 ft to 8000 ft., without the added expense of additional hardware or control panels.
