OPERATION
The red LED in the interconnect door in the back box lights when power is turned on, and
the fan operates to exhaust heat from inside the back box when a dome drive is installed.
If you have an outdoor pendant model with a heater, the heater elements in the back box
turn on at 70°F (21°C) and turn off at 85°F (29°C). The heater element in the lower dome
turns on at 40°F (4°C) and turns off at 60°F (16°C). The fans in the back box operate
continuously when a dome drive is installed.
NOTE:
For hard ceilings,
such as concrete, where the
wiring must be installed in
surface-mounted conduit, use
the optional BB5-PCA-BK
(black) or BB5-PCA-GY
(gray) Pendant Conduit
Adapter.
