Personally, I am not aware of a specific requirement to have them in the car by NFPA 72 but if they are 72 addresses the audible level. The direction may come from ANSI/ASME A17.1 but I don't have it and can't find a "free" access to date

fm, the bulk resource website has the elevator code as adopted by several states. I don't have it bookmarked on this computer, maybe somebody else has the link.

@Paul,

Thanks...I always keep forgetting that one. Don't see a TX version so I'm checking MN (pdf) but it downloads real slow (insert cricket sounds).

Wow..........15 minutes later couldn't find anything in MN except for audible alarm for unwanted access to top of cars. I'm tired
