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).

• Route wire using either method shown(Fig. 3-5).
• Securely fasten wires to wall as you go.
