Installing
Determine the Proper Location of the Daylight
Sensor Using the Adjacent Diagram.
• The arrow on the daylight sensor points toward the
area viewed by the sensor.
• The effective window height (H) starts 3 ft (1 m) up
from the floor or at the window sill, whichever is
higher, and ends at the top of the window.
• Place the daylight sensor so its viewing area is
centered upon the nearest window at a distance of
between 1–2 H from the window.
• Ensure that the view of the daylight sensor is not
obstructed.
• Do not position the daylight sensor in the well of a
skylight or above indirect lighting fixtures.
Mounting the Daylight Sensor
• Drill a 3/8 in (10 mm) diameter hole in the ceiling tile
or pendant fixture.
• Thread the wires through the hole.
• Install the daylight sensor into the hole.
• Secure the daylight sensor with the mounting
hardware provided (hand tighten only).
Note: If the stem of the daylight sensor must be
shortened because of its location (e.g., in a pendant
fixture), this should be done prior to wiring.
Wiring to a Sensor Input
• Connect the sensor wires as described:
Wire Terminal
Red 20 V-
Black Common
Yellow Daylight Signal
White IR Signal (cap if not used)
• Make sure that the supply breaker to the control
system is OFF.
• Use only 22 AWG (1.0 mm
2
) solid wire.
• If IR output is not required, the white wire should be
terminated.
• A sensor can be wired only to a single control
module or sensor interface.
• Each input on a control module or sensor interface
can have only one daylight sensor connected to it.
