Period. Well...close. Fire alarm and control systems vary for elevators and occupancies a bit. While mentioned above, they may not be 'required by the elevator manufacturer' but rather required via code by the AHJ. In my experience, the elevator inspector is God. I've seen entire jobs grind to a halt for a failed elevator inspection. NO ONE messes with the elevator inspector in my experience. You need them to sign off for occupancy, and if you fail your test it might be 3 weeks before he will come back and try again. I've had to change a couple things to pass: 1. One application specified two Cat5e drops to every phone jack, one for voice and one for data. In the elevator room we put the data jack on a faceplate, then ran the phone wire in conduit to the controller for connection to the car cable. Since the data jack wasn't integral, we were forced to pull the data wire back out and cover the box. 2. One installation the electricians had run metal conduit on one wall of the elevator mechanical room to a GFCI receptacle outside of the room, on an exterior wall. Since it was not a circuit for that room, they had to pull it out and re-route it. 3. One fire alarm installation we had a row of boxes on the wall with modules in them, basically the box takes an RS-485 data signal and addresses a relay to do a function. Six boxes, six modules, one of them actually for something not directly connected to the elevator circuitry and we had to pull it out and re-route everything. I'd never even consider placing radio equipment in there first due to the obvious code violation, second due to the life safety liability. 73 N7HQR
