Is it not in line with NFPA 72 to have the horn/strobes in the AOR, silenced due to not being able to hear the voice-intercom in that area or maybe using a different tone/sound, like a chime only in the AOR?
What is AOR?
Hospital term? or other
Area Of Refuge
I want to say no.
Plus it just might be close to impossible for a system to do that.
If you are talking about someone speaking into a microphone. When the key it up, it overrides the tones or voice evac message.
Definitely a case of code constipation (a high level of constraint or restriction; a pronounced lack of ease). Simple - locate the horn out of the AOR. When an occupant traveled the AOR, they already acknowledged the occupant notification requirements.
For health care occupancies only staff is to hear and respond the audible alarms in the private mode of notification per NFPA 72.
Silencing the horns in the AOR in other occupancies may give a false impression to people of no fire in the building just a false alarm.
