Installation instructions for the HAI 56A00-1 Recessed Door/Window Transmitter.
Installation instructions for the HAI 56A00-1 Recessed Door/Window Transmitter — a supervised wireless contact designed to be concealed within a door or window frame for a virtually invisible installation.
The 56A00-1 works with the HAI 45A00-1 Wireless Receiver and is supplied with a replaceable lithium battery rated for 5 years under normal operation. Because it's recessed into the frame itself, there's no visible sensor or wiring — the transmitter and matching magnet are drilled directly into the door/window frame.
Use a flathead screwdriver to open the 56A00-1 to change tops or access the battery.
Careful placement is important — the transmitter has two interchangeable tops (flush mount or flanged/screw mount) in case a hole is drilled slightly oversized or extra support is needed. The magnet does not have a flanged option, so its hole must be drilled for a tight, snug fit.
Tip: If you accidentally drill the magnet-side hole too big and it becomes loose, you can instead mount the transmitter in that position and use the flanged cap to screw it securely into place.
