The 4497SQ is a "wired" handicap button wall switch designed for interior use only. It measures 4.5" x 4.5" and requires that the wire from the wall switch is run back to the automatic door opener. Its best installed when walls are open so that the wire can be hidden behind the walls and may also be installed in conduit on the exterior of a wall.
The interior of the unit is gained by accessing the Allen screw under the cover (at the bottom) and removing the cover.
This wireless ADA push button wall switch must be installed indoors only.
