Description

The OAC-U Ceiling Mount Line Voltage Occupancy Sensor is an Ultrasonic (US) motion sensing lighting control,
used for energy savings and convenience. The sensor produces a low intensity, inaudible sound to detect occupancy
in a room. Changes in the sensor's acoustic wave caused by motion, such as walking in the room, reaching for a
telephone or swiveling in a chair, will cause the lights to turn ON. The sensor does not respond to audible sound.
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
minimum of 4 to 6 feet.

Installation

The OAC-U sensor can be mounted to a standard 2.125" deep x 4" octagon or 2.125" deep x 4" foursquare electrical
box (foursquare box requires a two-gang mud ring).

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 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)
