Specifications
Description
The OAWC-P Wall/Corner Mount Low Voltage Occupancy Sensor is a Passive Infrared (PIR) motion sensing lighting control, used
for energy savings and convenience. 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 disconnected from the red, causing the relay
to open turning OFF the load. The red lead is 10 to 30 VDC supply, the black lead is common and the blue is the relay control.
PIR Technology
The sensor’s segmented lens divides the field of view into sensor zones and detects the changes in temperature that are created
when a person, or part of a person as small as a hand, passes into or out of a sensor zone.
The sensor includes self-adaptive technology that continually adjusts to conditions by adjusting sensitivity and time delay in real-
time. By adjusting sensitivity and time delay automatically, the sensor is maximizing the potential energy savings that are available in
the particular application.
The Daylighting feature (-R model only) prevents lights from turning ON when the room is adequately illuminated by natural light.
The Walk-Through feature maximizes energy savings by not leaving the lights ON after a momentary occupancy. The sensor
will switch the lights ON when it detects a person entering the area. If the sensor does not continue to detect motion 30 seconds
following the initial activation, it will automatically go to a shorter 2 minute time delay.
In Automatic On Mode, the lights turn ON when a person enters the room. In Manual ON Mode, the lights are turned ON by
activating a momentary switch (model # GMDS-*) that is connected to the sensor. When used with 2 level lighting (-R model only),
bi-level Automatic ON can be achieved which allows Zone 1 to come ON automatically upon occupancy. Zone 2 does not come ON
unless the occupant presses the optional momentary switch.
Location
The maximum coverage area may vary somewhat according to room shape and the
presence of obstacles. Follow the coverage diagram concerning major and minor motion
coverage. 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 10 feet. Mount the sensor so the device faces the open portion of the room and
are facing a nearby wall, door, window, or other obstructing object. Avoid pointing into
hallways. To prevent false activation, the sensor should be mounted away from the air
supply duct a minimum of 4 to 6 feet. Mounting at fixture height is most effective. For
typical placement refer to Location Diagram.
Installation
The OAWC-P-120W can be mounted to the wall, 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 compliance 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 wall, 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)
