I was told the exact same thing in my last code reveiw which was the last available as well. I was in Woburn Electrical with Bob M and he had a guy come in for a few of the nights. The story was told to me that the electrician didn't offer any instruction with the install, as in the alarm goes of leave the house and call from a cell or a neighbors phone, and he testified to this that he didn't give any detail on what to do in the event of an alarm.
Since that class I tell all customers the leave the home and call the fire dept no exceptions.
Kind of stupid if you ask me as I can remember Daffy Duck doing comercials about what to do when the alarm goes off or you smell smoke. Check doors for heat, don't hide under the bed or in the closet, escape routes and a meeting spot.
Nothing has changed as far as responsability I guess, no one wants it.
