OPERATION:
WARNING: As per UL/ULC regulations: When the NMC is triggered for alarm by the FACP, either in
Master Mode or Slave Mode, NO other initiating devices may be wired to the NMC zone inputs.
2.2 Master Mode
In Master Mode, when an alarm occurs, the NMC requires the pressing of both the 'ALARM SILENCE' and
'RESET' buttons to silence the ISDs and reset the alarm condition. Using Zone 1 (or Z2) inputs and the FACP Dry
Alarm Contact Relay, connect zone wires to relay's common and normally open terminals with a 3.9K ohm, ¼
watt resistor in parallel (across the terminals) to supervise the wires. See
schematic.
