Notification appliance circuit wiring
The control panel does not have an onboard NAC. Use a D192G Notification Appliance Circuit
Module for systems requiring a NAC.
Programming determines the output format and the conditions that activate the output. One
self-resetting circuit breaker protects against shorts. When using the output to activate
notification appliance circuits in UL Listed fire alarm applications, install a D192G Notification
Appliance Circuit module.
Refer to the D192G Notification Appliance Circuit Module Installation Guide (P/N: 4998122260)
for detailed wiring information and specifications.
