CAUTION: RISK OF ELECTRICAL SHOCK. Turn power o at service panel before beginning installation. Never wire energized electrical components.

Read and understand all instructions before beginning installation.

NOTICE: For installation by a licensed electrician in accordance with

National and/or local Electrical Codes and the following instructions.

NOTICE: For indoor use only.


Confirm that device ratings are suitable for application prior to installation.

NOTICE: Do not install if any damage to product is noticed.

Sensor Operation


1.Turn power o at the service panel.

2.Remove the old switch(es) if applicable.

3.Wire as shown in the Wiring Diagram section. A secure connection to ground is necessary for the sensor to function properly.

4.Install sensor in wall box using mounting screws provided.

5. Restore power to the sensor and allow it to warm up (up to 2 min.). 6. Remove the sensor’s cover – see Adjustments section.

7. If desired, calibrate the photocell sensor and adjust the sensor’s configuration switch settings as described below.

8. Reinstall the sensor’s cover.

9. Install a Decorator style wall plate (not included).

Test Mode – to enter test mode: 1. Make sure lights are on.

2.Press and hold the ON/OFF button until the lights cycle o then back on. For dual circuit sensors, press and hold the ON/OFF button for Circuit A. For No-buttonsensors, press and hold the Test Button. See Sensor Operation Diagram.

3.Sensor is now in test mode. Vacate room, lights should turn o after 5 seconds. Step back into room (sensing zone), lights will turn back on. Repeat as necessary to confirm sensor is operating and detecting in the lighting zone as desired. Sensor will flash red or green LED to indicate Passive Infrared or Ultrasonic occupancy detection as applicable.

4.To exit Test Mode, press any button. Note: Sensor will automatically exit Test Mode after 1 hour.

Manual Override – Press button(s) to place sensor in manual mode. Lights will turn o and remain o while occupancy is detected. Sensor will return to automatic mode when button is pressed again to turn lights on or when the sensor’s timer value is reached. Note:No-buttonsensors cannot be manually turned o .

Air-Gap Override – If it is necessary to service the controlled circuits withoutde-energizingthem at the breaker panel (this is not recommended as a standard procedure):

1.Remove the sensor’s cover plate (see Adjustments section).

2.With the circuit(s) on, turn the air-gapswitch to OFF (toward the outside of the sensor).

3.Push the button(s) to turn the circuit(s) OFF.

4.Push the button(s) again to verify override.

The air-gapswitch will now interrupt sensor operation, preventing output(s) from turning on again, regardless of occupancy or pushbutton conditions. To return the sensor to normal operation, flip theair-gapswitch to the ON position and push the button(s) to return the circuit(s) to Automatic mode.Re-installthe sensor cover. Note: Sensor cover cannot bere-installedunless theair-gapswitch is in the ON position.


Open the sensor cover by inserting a small blade screwdriver into the catch at the bottom of the sensor and gently snap the cover loose. Set the adjustment switches as desired (see Configuration Switch Settings below). To re-installcover, insert catches at top of cover into recesses in sensor housing and gently snap cover into catch at bottom of housing.


The photocell is used to detect if other light sources such as sunlight, are enough to illuminate the space without turning on the lights. For Dual Circuit versions, only Circuit B is controlled by the photocell. The sensor is shipped from the factory with the photocell control disabled. If use of the photocell is desired, calibrate the photocell set points as follows:

1.Remove the sensor’s cover plate.

2.With the sunlight at the desired level where the lights should turn on, press the photocell button.

3.Step back from the sensor to avoid changing ambient light levels in the room. Note: During calibration the sensor will turn the lights o and on.

4.After the calibration process is complete (approx. 3 min.), reinstall sensor cover.

Configuration Switch Settings

Switch Settings (as seen on front of sensor)

switch toggle direction

Note: The sensor is shipped with all switches in the factory default (o ) condition (switches positioned toward edge of sensor).

Switch 1 – Auto/Manual

Controls selection between Auto ON/Auto OFF Mode and Manual ON/ Auto OFF Mode. For Dual Circuit versions, this switch controls Auto/ Manual Mode for Circuit A only.

Switch 2 – Auto/Manual B (Dual Circuit Versions Only)

Controls selection between Auto ON/Auto OFF Mode and Manual ON/ Auto OFF Mode for Circuit B.

Switch 3 – Photocell Mode

Controls selection between One Way Mode and Continuous Mode. In One Way Mode, the sensor turns lights on in response to occupancy when light levels are below the photocell set point then maintains them in the on condition regardless of light level. In Continuous Mode, the sensor functions the same as One Way Mode, except that during periods of occupancy it will turn the lights o if ambient light levels increase su ciently to illuminate the space. Note: For Dual Circuit versions, the photocell controls the operation of Circuit B only.

Switches 4 and 5 – Timer 1 and Timer 0

Use to set the initial timer value that the sensor will maintain lights on without detecting occupancy. See Auto/Fixed Timer below for additional information.

Switch 6 – Auto/Fixed Timer

Controls selection between Adaptive Timer Mode and Fixed Timer Mode. In Automatic Adaptive Timer Mode, the sensor will use the timer interval setting from switches Timer 0 and Timer 1 above. It will then begin adjusting it’s timer settings as appropriate for the lighted space to optimize performance based on occupancy patterns. In Fixed Timer Mode, the sensor’s self-adaptingtimer functions are disabled and the sensor maintains the lights in the space according to the switch settings of Timer 0 and Timer 1.

Switch 7 – Hallway

Disables or enables the sensor’s hallway algorithm. When enabled, this feature reduces false tripping of the lights associated with hallway tra c outside the room where the sensor is controlling the lights. This feature should be enabled when the sensor is installed facing toward the entryway into the room and sensor’s range of detection extends into a hallway or adjoining areas with occupancy.

Switch 8 – Adaptive Reset

When toggled on then o , this switch resets the sensor’s adaptive timer and sensitivity settings. The adaptive timer is reset according to Timer 0 and Timer 1 above. The adaptive sensitivity (both PIR and Ultrasonic as applicable) are reset to factory default. The Photocell Sensor is also reset to factory default (disabled) such that the sensor will turn on the light(s) in

response to occupancy regardless of ambient light levels in the lighted space.
