1. Mounting brackets.
• Mark both sides of garage door frame or wall
5" above floor. Fig. 3-1.
• Hold bracket [38] against door frame or wall.
– Check if brackets extend out from wall far
enough, so tongue of bracket is beyond
door, tracks or any door hardware.
– If not:
a. STB bracket extensions are available
at local dealer.
b. Blocks of wood, etc. may be substituted
for extensions.
• Center bracket on your mark Fig. 3-2.
• Fasten each with 2 screws [40]. Fig. 3-2.
(Tongues should point toward each other.)
NOTE: Mounting brackets can be attached to brick
walls or concrete floor using masonry 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, and place Red
LED here 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 from the door opening
where they will spend more time in shadows.
