MOUNTING THE
SENSOR (Cont’d)
5.
Hold the Door Mounted Safety Sensor extrusion up to the top of the door. Insure that the extrusion is oriented
correctly as shown below.
6.
Mark and drill the extrusion (as shown in pictures 8, 9 and 10 below) where the mounting holes (one at each end)
should be located. Also, be sure to mark and drill the proper end for an additional hole to be used for wire passage.
Wire passage hole should be approximately ¼” diameter. Screw mount holes only serve as a pilot hole for ease of
installing the self-drilling screws that are provided.
7.
Hold the DMSS back up to the door at the pre-drilled location and attach the unit to the door with the 2 screws
provided (as shown in picture 11 below). Insure the DMSS extrusion is tight against the door.
8.
If Door Mounted Safety Sensors are to be mounted on both sides of the door, a wire passage hole will be required
through the door to go from the approach side to the safety side, as shown below. Again, be sure not to drill through
any through-bolts or braces within the door. A cutaway view below (Picture 13) shows wire passage through the
door. Picture 12 and 14 shows an approximate location for the wire passage hole. The extension wire going between
the terminal blocks should be approximately 18” long and can then be cut back if needed. Refer to the detailed
drawing below for wire routing, connector and cable location.

NOTE: Take care to avoid screw holes near the seams of the door, where it may be difficult to drill and install
a screw, and possibly damage the inside structural braces of the door.
