A while back I hit a road block when I questioned the installation of tornado sirens in our area, these are mostly fed via utility or off government buildings.
The problem I run into was the installers was putting the maintenance disconnect down at ground level, about 6' off the ground, where any devious kid can just switch it off, there is no locks on them, and I went all the way to state level, and was told they had no jurisdiction because they were implemented into law by legislation, which meant hands off for local enforcement also.
I would presume these would be considered as a life safety device, and if as such they need the maintenance disconnect up at the control box, not down where kids can shut them off, or at least a lock on them.
I would think the bodies in interest who has required them would also require them to meet some kind of NTRL listing if they are considered a life safety device, no different from a fire pump?
