What is the Honeywell SD500-LIM?

SD500-LIM line isolator modules are compatible with Honeywell Silent Knight® fire alarm control panels (FACPs). SD500-LIM line isolator modulescan be used on Style 7 (Class A) and Style 4 (Class B) wiring configurations. SD500-LIM line isolator modulescan isolate a short circuit wiring fault on anSLC loop. Normally if a short on the SLC loop occurs, communication on the loop can be disrupted. When isolator modules are used and a short occurs on the SLC loop, it will be detected as a trouble but all the SLC devices that are protected by a line isolator module will continue to operate. SD500-LIM line isolator modulesmount in a standard dual gang or 4 inch square electrical box.
