Designed to resist false activations in high airflow applications, the OEC-U-XXXX-AF is an
ultrasonic motion sensor with built-in timing and load control relay driving circuitry. The sensor
produces a low intensity, inaudible sound. It detects changes in the sound waves caused by
motion, such as walking into a room, raising a hand in class, turning in a swivel chair, etc.
Model OEC-U-XXXX-AF, with Airflow Tolerant Circuitry(TM), reacts only to the portion of the fre-
quency spectrum which contains object motion while filtering the portion which relates to air
movement. When the sensor detects motion, the pre-set time delay period is started and the
blue wire is electronically connected to the red wire. This energizes the relay in the switchpack
which turns on the load. At the end of the pre-set time period, the blue wire is disconnected
from the red, causing the relay to open which turns off the load. The red lead is +15 VDC sup-
ply, the black lead is common and the blue is the relay control.
Product Mounting Location
Sensor:
Choose the sensor location carefully. The sensor must have a clear view of the area to be con-
trolled. It should not be blocked from “seeing” people by high partitions. The sensor will not “see”
through glass. Mounting height should be kept below 12 feet. Avoid pointing into hallways. To
prevent false activation, the sensor should be 4-6 feet mounted away from the path of strong air
turbulence. For indoor use only. For typical placement, refer to the Location Diagrams.
If partitions between 49” to 71” are present, see Coverage Diagrams. For greater partition
heights, each partitioned area should be treated as an individual space with floor to ceiling walls.
Additional Greengate sensors may be used to extend the coverage of the OEC-U-XXXX-AF.
Switchpack:
The switchpack is generally mounted above the ceiling on
the outside of the junction box that contains a hot line, neutral
and the existing switch leg from which the lighting is controlled.
If additional switchpacks are required, they are mounted on the
outside of the boxes containing the appropriate switch legs.
In installations where there are no existing switch legs, the
switchpack may be mounted on the outside of any conventional
standard junction box, with or without an extension ring.

CAUTION: Before installing or performing any service on a Greengate system, the power MUST
be turned off at the branch circuit breaker. According to EC 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.”
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.

where Class 2 wiring is not permitted, the switchpack can be mounted internally to any
standard electrical box.
Limited Warranty
Wiring
LED will not turn ON:
• Verify 10-30 VDC across the red and black wires of the sensor.
• If there is no power at the sensor, check for 12-18 VDC at the switchpack output and
correct voltage at the switchpack input. Verify correct primary connections.
• If the voltage is OK at the switchpack, recheck all wiring and connections.
• If the LED still does not operate, please contact Cooper Controls’ technical service.
Lights will not turn ON:
• Confirm that no other switches or equipment are interrupting or bypassing power to the
switchpack or load.
• Short the blue and red switchpack control leads together to energize the relay.
• If the lights turn on, contact Cooper Controls’ technical service.
• If the lights do not turn on, check wiring on the switchpack load side and check the
switchpack contacts for continuity. Replace the switchpack if necessary.
Lights will not turn OFF:
In smaller rooms, the sensor may be activated by people moving in the hallway outside the room. Adjust the
Range control 1/8 of a turn decrements in the counter-clockwise direction or relocate the sensor. If the lights
will not turn OFF after the time period set on the sensor, and the LED has not lit during the time period:
• Confirm that no other switches or equipment are interrupting or bypassing power to the switchpack or load.
• Verify that the override switch on all sensor circuit boards is in the “auto” position.
• Check all connections to the switchpack.
• Temporarily unplug the sensor circuit board(s).
• If the lights turn off, the sensor is defective, and the circuit board should be replaced.
• If the lights do not turn off, replace the switchpack.
NOTE: If multiple sensors/switchpacks are installed, check one at a time.
Manual-On Override Switch:
The OEC-U-XXXX-AF has a built-in override switch on the printed circuit board designed to turn the load
on in the event of sensor failure when the sensor can not be replaced immediately. The switchpack must
be operative for this switch to work. If the switchpack is defective, it must be replaced or bypassed to
activate the load.
To operate this switch, remove the cover of the sensor and move the override switch from the “auto” posi-
tion to the “on” position. All switchpacks connected to the sensor will now be energized. If multiple sensors
control the same switchpack(s), activating the override
switch on any one sensor will activate all switchpacks.
Sensor Cover Removal:
1. To remove the cover from the sensor unit, grasp
the end of the cover opposite the adjustment controls
and pull down gently. Unit will snap open.
2. Locate override switch.
3. To replace the cover, position controls to line
up with the holes in the center of the cover.
Unit will snap closed.

Sensor:
Step 1: Pass wires through the
threaded mounting post and
interlock to the backplate.
Step 2: The sensor mounts to
normal ceiling tile through a
single 3/4” hole.
Step 3: When mounted, the
sensor’s slotted grills must point
along the path where motion is to
be detected.
Step 4: An adapter plate (ACMP)
is available to allow mounting to a standard fixture ring and junction box.
Step 5: The threaded mounting post may be cut down if it is too long to fit into the junction
box. When a flat ceiling is not available or mounting to an angled surface is necessary, please
use the mounting adapter (ACMA-03).
CA TION: Finger-tighten the nut to avoid stripping the mounting post.

Sensor Adjustments:
Once installed, the sensors must be adjusted for suitable sensi-
tivity and time delay. These adjustments can be made only after
the entire system is installed and power is applied to the switch-
pack and to the lighting circuit. Adjustments should be made with
the HVAC system on.
1. Using a small screwdriver, set the “Minutes” control to minimum by turning the adjustment
completely counter-clockwise. Set the “Range” control to the midpoint.
2. If override switches were installed, check their operation. Leave in the automatic position.
3. Stand completely still or leave the room. In approximately 15 seconds, the lights will go out.
4. Test the area of coverage by watching the red LED on the sensor. The LED lights only when
the sensor is detecting motion. Adjust the Range control to the lowest position that provides
adequate motion detection. Do not set higher than necessary. Test and set Range control for
each sensor if more than one was installed.
5. If the red LED blinks when no motion is being made or does not go off at all, air motion from
the HVAC system may be activating the sensor. Reduce the Range control until the LED goes
out and stays out when no one is moving. If this setting is too low to respond to normal
motion, the sensor may need to be relocated away from the air turbulence.
6. In smaller rooms, the sensor may be activated by people moving by the doorway outside the
room. Adjust the Range control toward minimum to prevent this.
7. Set the time delay Minutes control to the desired time for the lights to remain on after leaving
the area. Minimum time is approximately 15 seconds (for installer testing) - maximum is
about 30 minutes. The recommended time delay is usually 6-8 minutes. An eight-minute
time delay is approximately 11 o’clock on the Minutes control. People who remain very still
for long periods may need a longer time delay. If the lights go out while the room is occupied,
increase the time slightly until optimum time delay is reached.

CA TION: OEC- -XXXX-AF is for use with 10-30 VDC only. For other voltages, refer to Greengate Tech
Sheets. Do not wire to control receptacle circuits. Confirm supply voltage before wiring the switchpack.
Make sure the switchpack is the correct model for the voltage being used. VERIFY that the connected
load does not exceed the switchpack ratings. se twist-on wire connectors for all connections. All
installations should be in compliance with the National Electric Code and all state and local codes.
DO NOT control more than ten switchpacks with a single sensor.
Greengate sensors are provided with Teflon-insulated pigtails. The components are interconnected
using 18 AWG Class 2 wiring per NEC 725. se L-recognized Teflon insulated wire approved for
plenum areas per NEC 725-2(b) where required.
Wire the sensor(s), switchpack(s) and load as shown in the Wiring Diagram.
Controlling Multiple Circuits: CA TION: In situations where an office is wired for multiple circuits
using separate hot leads, it is very important to connect only one circuit to each switchpack. You
may combine the low voltage wiring from switchpacks connected to different circuits. Consult with
the building manager and occupant to determine which lights should be off when the toggle switch
is open.
