LOCATING SAFE-T-BEAM® for multiple doors
Transmitter (RED LED) and Receiver (GREEN LED)
Single Garage Door
• Determine which side of the garage receives direct
sunlight.
• Position the Transmitter (Red LED) on the direct sunlight
side.
Multiple Garage Doors
•
NEVER position Safe-T-Beam® modules where signals will
cross.
• Place the Transmitter (Red LED) Safe-T-Beams on adjacent
doors facing in opposite directions.
NOTE:
Direct sunlight creates interference with Safe-
T-Beam
®
Receiver (Green LED). STB modules CAN be
positioned further away from the door opening if
necessary to avoid sunlight but no further off the wall
to maintain alignment with the Transmitter (Red LED)
module.
NOTE:
Only use Safe-T-Beams® that are included with this opener.

use other brands or types of photocells
on this opener.
