What tones would you prefer for voice evac?

Not necessarily. Some jurisdictions have not yet adopted those editions of code (eg. there’s a town I know of that still uses the 2002 edition of NFPA 72) or have their own additional codes that supersede NFPA.

When a jurisdiction adopts an NFPA code, they can choose to adopt the whole thing in its entirety or they can adopt it with their own changes thrown in. The latter is usually what ends up happening. So, some jurisdictions write that they want xyz in their voice evac tone instead of temporal-3, or they want continuous for their horn-strobes. They are totally allowed to do this, because NFPA codes are really just standards.

When you get to some cities like Las Vegas or Chicago, those places have very stringent local codes that are far more specific than any NFPA code, and those codes take precedence over NFPA.

I would like some sort of code 3 whoop and a script that says “may I have your attention please, the property emergency system has been activated, the emergency response team is currently investigating the cause of the alarm” and some sort of evacuation directions.
