My dream is to hear one

The NFPA doesn't require temporal coding though.

@@AspiringHotelManager Unfortunately it does, & it’s a requirement for many local jurisdictions as well on all new F/A system installations. Apparently it’s been code since 1996, but hasn’t been aggressively enforced up until recent years depending on the state & city. Any notification appliance used solely for the evacuation of occupants during a fire emergency must emit a temporal 3 coding. I found this out when installing a 4100ES system in a 25 story condominium building near the Ala Wai canal in Waikiki. I even brought it up to the inspector because I was hoping to use whoop. We would not have passed inspection if we used whoop according to him. From my understanding, older & existing systems are grandfathered in & exempt from this code, but any major modifications to original systems would require temporal 3 coding to be implemented.

@@oahusirens , I used to know a firefighter, he told me it's not required. It is required for systems to be able to do code three, but your fire depatment, state fire marshall, local authorities who have jurisdiction have final say. NFPA recommends you use code three, but they don't require it. He also told me, his department didn't care what the evacuation signal was. They just wanted people to get out of the building. They only use code three in his jurisdiction, because the nfpa uses it, but code three or not didn't matter.

Yeah

I don't know, maybe somebody out there in KZfaq land may know.

I don’t understand how it does that like it plays the Whoop tone. first then the code 3 tone.

@@jacobisworld9516 It's programmed to do that in the software.

Really

The camera is probably close to the panel. Had a similar voice evac system at my high school, those are VERY LOUD. (well, at least that one was.)

Thanks

@@jzzhang726 Is this At A college

@@jacobisworld9516 I think so

The Whoop Tone And The Code 3 Tone.

I Don’t Understand Why It First Does The Whoop Tone Then After The Voice Message Then It Plays The Code 3 Tone.
