Application Examples Controlling NACs, Aux Power, and Door Holders with NAC Sync
B.4 Controlling NACs, Aux Power, and Door Holders with NAC Sync
In this application, use of a single SK-RELAYMON-2 mounted inside the cabinet can monitor the two power supply trouble relays and trig-
ger two independent inputs via relay circuits. SK-PS outputs #1 and #2 are being used for 24 VDC aux power triggered by the module’s relay
circuits. Any SK-PS output circuit can be configured to follow any input circuit.
The following notes apply to Figure B.4.
• Any output circuit can be configured as NAC, door holder, or 24VDC power.
• Refer to Section 3 for instructions on setting the DIP switches.
• Do not loop wires under screw terminals. Break wires to maintain proper supervision.
• An End-of-Line Resistor must be installed between terminals 1 and 4 for module wiring supervision (the ELR value is dependent on the
module/FACP employed).
• An End-of-line Resistor on input circuits#1-2 (TB5-6) are optional for this particular application.
• Ensure that the SK-RELAYMON-2 is programmed appropriately at the FACP where the inputs are not mapped to the same zone as its
outputs.
• For a list of compatible devices, refer to the Silent Knight Device Compatibility Document #52612.
• Refer to the SLC Wiring Manual for more information.
