Fire Alarm
Fire alarm regulations now include audio and video components and establish performance requirements of these components that could create a new business opportunity for A/V integrators.
December 06, 2012 | by Aaron Stern

Emergency announcements aren’t much good if they are unintelligible at critical moments, so ensuring their clarity is vital.

The most recent revision of NFPA 72, the National Fire Alarm and Signaling Code, recognizes audio and video components as vital parts of emergency notification systems.

The performance requirements of these new safety components have created a new business opportunity for A/V integrators to potentially work with fire alarm companies.

As illustrated in the below video from analysis equipment maker Gold Line (this video is the third in a series of training videos from Gold Line), determining the acoustics of the rooms within a facility is essential to ensuring exit instructions can be understood.

Integrators must consider a variety of aspects including the dimensions of the room, the materials used within the room and the location of the loud speakers.

Gold Line also released this video below that shows how to set up the Gold Line TalkBox for injecting the STI-pa Test Tone in to the emergency control panel within a facility.
