Abstract
A method for selectively transmitting audio signals in a fire alarm system includes receiving, by a Notification Appliance Circuit (NAC) selecting device, an audio signal for transmission over a first NAC or a second NAC. Each of the first NAC and the second NAC includes respective groupings of one or more NAC appliances. The NAC selecting device receives a selection signal from a Fire Alarm Control Panel (FACP) electronically connected to the NAC selecting device. The selection signal identifies one or more NAC appliances that should be moved from a first grouping corresponding to the first NAC to a second grouping corresponding to the second NAC. The NAC selecting device selectively transmits the audio signal to one of the first NAC and the second NAC based on the selection signal.
