No horror stories, but a funny story. A hospital in the Memphis, TN. area
was having problems with tampering with valves in the stair towers of a 6
story parking structure. Signs didn't help, so one day the fire marshal for
the hospital had an idea. He got about 6 feet of 24 pair phone wire from the
maintenance dept. Skinned the outer cover off, wrapped it around the pipe
and valves at the floor control assy. so all the pretty colors could be
seen, taped the ends behind the junction box for the flow switch. Never had
another problem with tampering. He also had a problem with folks stealing
fire extinguishers from the cabinets in the elevator lobbies of the same
garage. He taped a single multi colored wire down the inside of the clear
plastic cover so it was clearly visible. No more problem, which was funny
because if you looked you could clearly see both ends of the wire.

Subject: Floor control valves
I'd asked this previously, but got zero responses.
What's the ideal height within a stairway to install the floor control
valve assembly? The lower they're installed, the odds of them being
tampered with increases. The higher they're installed, the more it could
delay shutting down the sprinkler system following a fire or accidental
discharge. Any horror stories one way or the other?
