Specifications
Description
Ultrasonic
Activated
The OAC-DT Ceiling Mount Low Voltage Occupancy Sensor is a Passive Infrared (PIR) and Ultrasonic (US) motion
sensing lighting control, used for energy savings and convenience. PIR is used to turn the lights ON and then either
technology is used to keep the lights ON. When motion is detected, the blue wire is electronically connected to the
red wire, energizing the relay in the switchpack to turn on the load. If vacancy is detected, the blue wire is discon-
nected from the red, causing the relay to open turning OFF the load. The red lead is 10-30 VDC supply, the black
lead is common, and the blue is the relay control.
The sensor includes self-adaptive technology that continually adjusts to conditions by adjusting sensitivity and Time
Delay in real-time.
Location
The maximum coverage area may vary somewhat according to room shape and the presence of obstacles. Decrease
total coverage area by 15% for “soft” rooms (for example, heavy draperies or heavy carpeting). The sensor must have a
clear view of the area to be controlled. The sensor will not “see” through glass. Mounting height should not exceed 12
feet. Optimum mounting height is 8 to 10 feet. Mount the sensor so the grilles face the open portion of the room and are
not facing a nearby wall, door, window, or other obstructing object. Avoid pointing into hallways. Mounting at fixture
height is most effective. *To prevent false activation, the sensor should be mounted away from the air supply duct a min-
imum of 4 to 6 feet.
Installation
The OAC-DT sensor can be mounted to the ceiling, junction box, or round fixture with raceway.
Wiring
CAUTION: Before installing or performing any service on a Greengate system, the power MUST be turned OFF at
the branch circuit breaker. According to NEC 240-83(d), if the branch circuit breaker is used as the main switch
for a fluorescent lighting circuit, the circuit breaker should be marked “SWD”. All installations should be in com-
pliance with the National Electric Code and all state and local codes.
NOTE REGARDING COMPACT FLUORESCENT LAMPS: The life of some compact fluorescent lamps (CFLs) is shortened
by frequent automatic or manual switching. Check with CFL and ballast manufacturer to determine the effects of cycling.
1. Make sure power is turned OFF at the branch circuit breaker.
2. Wire units as shown in wiring diagrams per applicable voltage requirements. (Use twist-on wire connectors
for all connections) CAP ALL UNUSED WIRE LEADS.
3. Mount unit to ceiling, junction box, or round fixture with raceway.
4. Turn power back ON at the branch circuit breaker and wait 2 minutes for the unit to stabilize.
5. Make necessary adjustments. (See Checkout and Adjustments section)

Manual Mode Operation:
Switches are required to
turn corresponding loads ON.
Lights turn OFF when sensor
times out or with the
switch.
Automatic Mode Operation:
Sensor turns ON both
switchpacks. Switches can
be used to turn lights ON
or OFF.
If daylight sensor is
enabled and light level is
above setpoint, switchpack
connected to yellow lead
will not turn ON.
