THREADS77 RTP SLOT Turn the key switch on. If your installation includes a key switch, however, run the red wire first to the key switch and then to the sounder. Start at the point farthest away from the sounder (the foil taped to a window or door glass, for example). Placing an indoor sounder in a closet or other confined space is not recommended. All switches must be closed, all wires have to be attached properly to switches under terminal screws, and no break can exist in the window foil.|Slot Canyons of Capitol Reef
