WARNING
DISCONNECT ALL POWER TO
GARAGE DOOR OPENER BEFORE SERVICING OR
INSTALLING ACCESSORIES OR PHOTOELECTRIC
SAFETY SENSORS. FOR ALL OPENERS, UNPLUG 120 V
AC POWER CORD FROM RECEPTACLE. FOR
DOORMASTER, ALSO UNPLUG TELEPHONE CORD TYPE
COMMUNICATIONS CABLE.
Select a mounting position, no more than 5 inches above the
floor to center line of wall mounting bracket. The sending 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”
flat head nail (provided) using the small hole above the slot.
Using two 5/16 x 1-1/2” lag screws (provided), permanently
mount the wall mounting brackets to both door jambs. In some
installations it may be necessary 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). Insert
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 sunlight. Since sunlight may affect photoelectric
sensors, you should mount the sending unit (not the receiving
unit) on the side of the door opening exposed most to the sun.
NOTE: If wires must be lengthened or spliced into prewired
installation, use wire nuts or suitable connectors.
Attach the sending and receiving units to the “U” brackets by
inserting their tabs into the respective holes.
