Step 18: Photoelectric Safety Sensor Installation					WALL
					MOUNTING
					BRACKET
Select a mounting position 5 inches above the floor
to center line of wall mounting bracket. The send-
ing and receiving units should be mounted inside the
door opening to minimize any interference by the sun.
However, the sensors should be mounted as close to the
door track or inside edge of the door as possible to offer					“U”
maximum entrapment protection. It is very important
					BRACKET
that both wall brackets be mounted at the same height
for proper alignment.			(1) 5/16 X 1-1/2”			NAIL
The brackets may be temporarily mounted to the jamb			LAG SCREWS
with a 1” flat head nail (provided) using the small hole
above the slot. Using two 5/16 x 1-1/2” lag screw (pro-		NUT
vided), permanently mount the wall mounting brackets		WASHER
to both door jambs. In some installations it may be nec-
essary to attach a wooden spacer to the wall to achieve
						5”
the required clearance.
Attach the “U” brackets to the wall brackets with a			1/4-20 X 1/2”
			CARRIAGE BOLT
1/4-20 carriage bolt, washer and nut (provided). In-
sert
the bolt from the inside of the “U” bracket and hand
tighten only at this time.
		RECEIVING UNIT
Identify which side of the garage door opening (if any)
is “likely” to be exposed to the sun. Since sunlight
may affect photoelectric sensors, you should mount the
sending unit (not the receiving unit) on the side of the
door opening most exposed to the sun.
NOTE: If wires must be lengthened or spliced into
prewired installation, use wire nuts or suitable con-						SENDING UNIT
