NOTE: The operator will not close the door
automatically unless the Safe-T-Beam

System is
installed.
1. Mounting brackets.
• Mark both sides of garage door frame or wall 5"
above floor.
(Fig. 3-1).
• Hold bracket against door frame or wall
.
– Check brackets extend out from wall far
enough that tongue of bracket is beyond door,
tracks or any door hardware.
– If not:
-“STB” bracket extensions are available
at local dealer.
-Blocks of wood, etc. may be substituted for
extensions.
• Center bracket on your mark (Fig. 3-2).
• Fasten each with 2 screws (44) (Fig. 3-2).
NOTE: Mounting brackets can be attached to the
floor using concrete anchors (not provided).
2. Mounting “STB” source and sensor.
• If garage has only one garage door.
– Determine which side of garage receives most
direct sunlight (Fig. 3-4).
– Red LED should always be on sunny side
whenever possible (Fig. 3-4).
• For multiple doors.
– Preventing crossed signals is critical.
– Place source and sensor modules on adjacent
doors facing in opposite directions (Fig. 3-4).
NOTE: To help prevent interference from sun, “STB”
sensors (Green LED) may be placed further away from
the door opening where they will spend more time in
shadows.
• Slide source/sensor onto tongue of bracket until
it clicks into place (Fig. 3-3).
There should be no electrical power to the operator
while installing Safe-T-Beam System
®
wires. If you
have plugged in the power cord—UNPLUG IT NOW.
