Step 1:
Press and hold the
[MODE]
button for 3 seconds to enter
“Program Mode.” Program Mode allows adjustment of the
preset that activates for occupancy detection. By default, this
is Preset 1. The “A” button, located on the front of the sensor,
blinks to indicate the preset number controlled by the
occupancy action.
Step 2:
Press and release the “A” button the number of times to set
the new preset. (For example: press and release ten times to
set Preset 10.) The “A” button blinks the number of the preset
used for the occupancy event action.
Step 3:
Press and release the
[MODE]
button to save the current
setting. The Mode/Sensor count LED turns off and the “A”
button again blinks out the saved preset index.
Step 4:
Attach the sensor to the mounting plate by aligning the tabs
on the sensor with the slots on the mounting plate, then twist
clockwise until the two are locked into place.
Vacancy Timeout
Vacancy timeout is the amount of time the sensor waits to take action after no
movement is detected. By default, vacancy timeout is set to 15 minutes
(indicated by DIP switch 3 set to Off and 4 set to On). When the vacancy
timeout ends, the grace period begins.
When the sensor detects vacancy, the vacancy timeout period begins. If the
sensor does not detect occupancy again during the vacancy timeout period,
the lights turn off and a 30 second grace period begins.
