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.

Abstract: A number of different approaches are described for minimizing or preventing false alarms. In one case, override panels are used such as locally near or in the protected space or remotely at a security desk, for example. These override panels are used to deactivate or block the generation of a fire alarm signal in the case where the occupants or a management personnel recognizes that the fire alarm signal should not be generated. In this way, an alarm verification step is included. In another aspect, additional, contextual information is used to characterize or adjust when fire alarm signals are generated. This contextual information can be generated from sources that are not typically used in the generation of the fire alarm signal but instead are based on other sources of the information concerning the protected space.
