* Class A Configuration Wiring:
The DCP-SCI short circuit isolator should be located between any devices on the SLC loop. In the event of a short on the SLC loop, the two adjacent isolators (closest isolators to the left and right of the shorted section) will activate and their respective LED indicators will be turned on. All devices between the active short circuit isolators will lose communication. This will prevent entire loop failure. Upon removal of the short condition, the DCP-SCIs will automatically restore the entire loop to the normal operating state.

The FN-4127-NIC Network Interface Card allows for the expansion of up to 64 nodes (combination of FACP’s or annuciators) on a single FireNET network wide system. Using the Loop Explorer configuration software up to 64 nodes can be programmed to respond to in a variety ways-independently or system wide.
