Re: Overhead Door Magnetic Contact

["Robert L Bass" <robertlbass@xxxxxxxxxxx>]

Paul,

The 957 is usually mounted to the bottom of the door.  The sensor part with
the cable connected is affixed to the floor using screws and anchors (there
are various types available at hardware stores) near one side of the door.
The magnet is affixed to the door itself such that the two are aligned and
nearly touching with the door closed.  When the door opens the magnet moves
away, causing the sensor to open the alarm circuit.

Another option is to mount the sensor to the wall above the door.  The
advantage to this location is the wire isn't likely to be snagged by rakes,
shovels and other household stuff that folks leave in the garage.  If you
mount it to the wall, just be sure to leave enough room so that the magnet
doesn't bump the sensor as the door opens.  The 957 has a 2" gap which means
that the magnet can be mounted nearly 2" away from the sensor.

If you need more specifics on the procedure, ask and I'll detail it a little
better for you.
