Silent Knight SD505-6IB

The SD505-6IB isolates a short circuit wiring fault on a Class A (Style 7) and Class B (Style 4) SLC loop. Normally if the FACP detects a short on the SLC loop, the entire loop can be disabled. When the SD505-6IB is attached to the loop, a short, open or ground fault occurring on the SLC loop will be detected as a trouble but all SLC devices will continue to operate. The isolator module fits underneath the SD505-6AB detector base. The SD505-6IB Line Isolator Module is compatible with Silent Knight Addressable Fire control panels. The SD505-6IB can be used onClass A (Style 7), and Class B (Style 4) wiring configurations. The SD505-6IB mounts on a standard dual gang or 4” square and Octagon electrical box. Up to 508 SD505-6IBs can be used per 5820XL, and 127 per 5808 Intelliknight systems.
