1. Mounting brackets.
• Mark both sides of garage door frame or wall 5"
above floor. (Fig. 2-1).
• Hold bracket 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. 2-2).
• Fasten each with 2 screws (47) (Fig. 2-2).
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. 2-4), and place Red
LED here whenever possible (Fig. 2-4).
• For multiple doors.
– Preventing crossed signals is critical.
– Place source and sensor modules onadjacent
doors facing in opposite directions (Fig. 2-4).
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.
• Slide source/sensor onto tongue of bracket until
it clicks into place (Fig. 2-3).
