ALD (Ambient Light Detection) Learn mode will turn lights on only if natural light in room is low. If 

switch turns on when there is enough natural light, or if switch does not turn on when there is not 

enough natural light, press the tap button within 5 seconds of entering the room. Over time, the 

switch will learn your preferred setting.

Test Mode

Test Mode is a short timeout (less than 15 seconds) that will test the coverage of the sensor at the 

current settings.

To enable Test Mode:

 

1.

 Wait 2 minutes after initial power up.

 2.

 Press and hold 

T

 until the PIR lens flashes (about 7 seconds).

 

3.

 The device will exit Test Mode automatically after 5 minutes of inactivity, or when any button is 

pressed.
Note:  An amber LED flashes to indicate PIR detection, a green LED flashes to indicate ultrasonic 

detection. You may hold 

P

 or   for 2 seconds while in test mode to test the current 

sensitivity of that specific technology.

Restore Default Settings

Press and hold   and 

P

 until all 

IL

 blink slowly (about 7 seconds). This will restore ALL of the 

sensor’s settings back to their defaults.

Off-While-Occupied

When Off-While-Occupied is Enabled:

 After manual shutoff, the sensor will keep lights off as long 

as the space is occupied and the timeout has not expired. This setting is best for rooms where 

presentations are given and lights may be kept off during occupancy. This is the default setting.

When Off-While-Occupied is Disabled:

 After manual shutoff, the sensor will keep lights off for 

25 seconds before looking for motion. If motion is detected, the lights will turn back on. This 

setting is best for high‑traffic areas like bathrooms and hallways.

Change Setting:

 

1.

 Press and hold   and 

P

 at the same time until an 

IL

 begins to flash (about 3 seconds).

 

2.

 Tap 

P

 to cycle to your desired setting.

 

3.

 Press and hold 

P

 until the 

IL

 goes solid to lock your selection.

Setting Fixed ALD Level

The light level you set will determine when a unit set in “ALD Fixed” sensor mode will turn lights 

on, or keep lights off, upon detecting occupancy. This setting only affects the behavior of a sensor 

in “ALD Fixed” mode.

Change Setting:

 

1. 

Press and hold 

M

 and   until an 

IL

 begins to flash (about 3 seconds).

 

2.

 The Ambient Light Detect light level will now be displayed on the 

IL

. Tap 

M

 to cycle to  

your desired setting.

 

3.

 Press and hold 

M

 until the 

IL

 goes solid to lock your selection.

To display current settings, tap the Timeout ( ), Sensor Mode (

M

or PIR Sensitivity (

P

) button. The indicator LED (

IL

) that corresponds to the current setting will 

illuminate.
