Step 17: Install Wiring for Wired Infrared Safety Sensor
Identify which side of the garage
door opening (if any) the sun is
“likely” to shine on to. Since
sunlight may affect infrared safety
sensors, you should mount the
sending unit on the side of the
door opening exposed to the sun.
Uncoil the wires from the infrared
safety sensors and route the wire
up the garage wall across the ceil-
ing and down to the back of the
power head, as illustrated. Tack
the wires in place using staples.
Take care to run the wires in a
location where they will not inter-
fere with the operation of the door
and do not staple through wire. Be
sure to leave about 12” of excess
wire at each end so you will have
enough slack wire to mount units.
Note: If wires must be lengthened or spliced into pre-
wired installation, use wire nuts or a suitable connec-
tor.
Step 18: Connecting Wired Infrared Safety Sensor to Opener
Connect Infrared Safety Sensors to power head
as per diagram. Shorten the wires as necessary
and separate the wire ends. Strip about 1/2" of
insulation off each wire and attach the wires to
the proper terminal screws, then tighten se-
curely, using a small blade screwdriver.
One wire has marking on it (numbers, black
stripe, etc). Be sure to observe polarity. Apply
tension to external wires to test for secure con-
nection. Check that the wires are stapled in
place.
