use with fire protective signaling units. Power connections are made via plug-in screw terminals.
NCB-EL Installation Requirements:
1) NCB-EL Network Combiner Module
2) SMX Echelon network transceiver
3) NCB Power Supply (24 Volt DC 400mA, center POSITIVE, outer NEGATIVE)
4) Ethernet cross-over cable for a direct connection, or a standard Ethernet cable otherwise (must be supplied
by customer)
5) NISCAB-5
6) HSP-121B Surge Suppressor
NCB-FL Installation Requirements:
1) NCB-FL Network Combiner Module
2) SMX Echelon network transceiver
3) CentreCOM Fiber Optic Transceiver with provided extension cable
4) NCB Power Supply (24 Volt DC 400mA, center POSITIVE, outer NEGATIVE)
5) HSP-121B Surge Suppressor
6) Bidirectional fiber optic cable (must be supplied by customer)
7) NISCAB-5
NOTE: The NCB power supply unit requires 115 VAC, 60Hz primary power.
