Description
The AHAWC-DT Wall/Corner 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 or both
technologies are 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 disconnected 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.
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 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 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 presence of obstacles. Follow the coverage diagram concerning major and minor
motion coverage. 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 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. 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.

CAUTION: Before installing or performing any service on a Eaton 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 two minutes for the unit to stabilize.
5. Make necessary adjustments. (See Checkout and Adjustments section)

1. Stand in different areas of the room and wave your hands.
2. If the Red LED does not turn ON, check for any obstructions.
3. Stand still six to eight feet away from sensor for five seconds. LED should not turn ON.
4. If Red LED turns ON without motion or is constantly ON adjust PIR sensitivity to 50% by moving DIP switch 5 UP.
Field-of-view outside the space
1. Adjust PIR sensitivity to 50% by moving DIP switch 5 UP.
2. Adjust Ultrasonic Sensitivity.
Daylight Adjustments (-R model only)
If this feature is not needed, leave the light level at maximum (fully clockwise).
The Daylighting feature prevents the lights from turning ON when the room is adequately illuminated by natural light. If there
is enough light in the room regardless of occupancy, the sensor will hold the lights OFF. If there is not enough light in the room,
the sensor will allow the lights to turn ON when occupied.
Full and Half Logic Modes (See DIP switch legend):
In both Full and Half Logic modes, lights connected to the yellow control lead will not turn ON upon occupancy activation,
should the ambient light level exceed the preset foot-candle level.
After activation:
Full Logic Mode – should the ambient light level exceed the preset foot-candle level, the lights connected to the yellow
control lead will turn OFF. The lights will remain OFF, until the ambient light level falls below the set point.
Half Logic Mode – the output state of the yellow control lead will not change with ambient light changes, after occupancy
activation. If the amount of natural light available rises above the setpoint, the daylight sensor will not turn the lights OFF while
occupancy is being detected.
Note: Set the light level when the ambient light is at the level where no artificial light is needed. In order for this feature to
function, the yellow control lead must be wired.
1. With the load ON, put the sensor into Test Mode. To place into Test Mode, toggle DIP switch 10 out of its current position,
wait 3 seconds and then back in to its original position.
2. Set DIP switch 10 to Full or Half Logic Mode.
3. Set the light level to minimum (fully CCW).
4. Leave the room and let the sensor time-out so lights are OFF. Enter the space and lights should remain OFF.
5. Make sure not to block the sensor from the daylight source and adjust the light level potentiometer CW in small increments
until the lights are ON. (Pause 5 seconds between each adjustment)
6. Once the lights are ON, the load connected to the sensor will not turn ON if light levels are above the current illumination.

Checkout and Adjustment
Adjustments should be made with the HVAC system ON. Use only insulated tools to make adjustments.
Self-Adjust
Sensor is shipped in the Self-Adjust Mode. This applies to time delay, US, and PIR sensitivity. In preparation for the
Installer Test, the time delay is set to 15 seconds, after the sensor is installed, powered ON and has stabilized, the unit will
time-out 15 seconds after the last motion detected. Coverage and sensitivity can be confirmed by watching the Green (US)
and Red (PIR) indicator LEDs on the front of the sensor, while moving around the room.
1. Walk around the room and monitor LEDs. LEDs should only turn ON for one second with each motion. (If LEDs do not
turn ON, go to Installer Adjustments - Sensitivity Adjustments Section)
2. Stand still six to eight feet away from the sensor for five seconds. LEDs should not turn ON. (If any LED turns ON, note
LED and go to Installer Adjustments – Sensitivity Adjustment section)
3. Walk outside the room and wait 15 seconds for the lights to turn OFF. (If lights do not turn OFF go to Installer
Adjustments Section)
4. Re-enter the room to activate sensor. (If lights do not turn ON go to Troubleshooting Section)
5. The unit will remain in Test Mode for 5 minutes then automatically exit Test Mode and go for 10 min. Time Delay User
Mode setting.
Note: To place into Test Mode, toggle DIP Switch 10 out of its current position, wait 3 seconds, and then back in to its original position. To force
into 10 min User Mode move Dip Switches 1 and 2 down. (If DIP Switches 1 and 2 are already down, toggle DIP Switch 1 out of its current position,
seconds, and then back to its original position) While in Test Mode, the LEDs will flash once per 1/4 second.

Installer Adjustments
Sensitivity Adjustments
Ultrasonic Sensitivity (Green LED) – Using a small flathead screw driver turn the green potentiometer so that the arrow
points UP.
1. Stand in different areas of the room and wave your hands.
2. If the Green LED does not turn ON, increase the US sensitivity by turning the green potentiometer clockwise in small
increments. Repeat Step 1.
3. Stand still six to eight feet away from sensor for five seconds. LED should not turn ON.
4. If Green LED turns ON without motion or is constantly ON decrease the US sensitivity by turning the green
potentiometer counter-clock-wise in small decrements. Repeat Step 3.
Time Delay Adjustments
People who remain very still for long periods of time may need a longer Time Delay than the default setting of 10 minutes.
As long as Auto is enabled, the sensor will respond to each pair of false-OFFs with no normal OFF in between, by alternately
making slight adjustments to either time delay (by 2 minute increments) or sensitivity, so there should be no need for manual
adjustment. If manual adjustment is desired, refer to Time Delay settings in DIP switch legend.
Reset sensor time delay to factory settings by moving DIP switches 1 and 2 down. (If DIP switches 1 and 2 are already down,
toggle DIP switch 1 out of its current position, wait 3 seconds, and then back to its original position)
Automatic Mode
In Automatic ON Mode, the lights turn ON when a person enters the room. If optional momentary low voltage switches are
used along with Automatic ON Mode, activating the switch(es) while the load is ON turns the load OFF. When the load is turned
OFF manually, as long as the sensor continues to detect occupancy the loads stay OFF. After the time delay expires, the lights
stay OFF and the sensor goes back to Automatic ON Mode. For wiring information for the optional momentary low voltage
switch(es), please see the wiring section of the installation instructions.
Manual Mode
In Manual ON Mode, the optional momentary low voltage switch(es) is required to turn the load(s) ON. Once activated the
sensor will maintain the lights ON until motion ceases and the time delay expires. While the room is occupied the BAS relay
remains active. After the time delay expires, the load(s) will automatically be turned OFF and the switch(es) must be used to turn
the load(s) ON unless there is motion detected within the 10 second re-trigger period.
Lighting Sweep Option
If selected, this DIP switch option forces an initial 60 second delay upon “power-up” to prevent false activation in buildings
with computer control systems.
1. Move DIP switch 9 UP.
Override
The Override setting allows the lights to remain ON in the unlikely event of sensor failure.
1. Move DIP switch 8 UP.
While in Override Mode, the optional low voltage momentary switch(es) will toggle the lighting load(s).
