Select a mounting position 5 inches above the fl oor
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
maximum entrapment protection. It is very important
that both wall brackets be mounted at the same height
for proper alignment.
The brackets may be temporarily mounted to the jamb
with a 1” fl at head nail (provided) using the small hole
above the slot. Using two 5/16 x 1-1/2” lag screw (pro-
vided), permanently mount the wall mounting brackets
to both door jambs. In some installations it may be nec-
essary to attach a wooden spacer to the wall to achieve
the required clearance.
Attach the “U” brackets to the wall brackets with a
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.
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-
nectors.
Attach the sending and receiving units to the “U” brack-
ets by inserting their tabs into the respective holes.
