2. Press and release the Auxiliary [A] button the number of times that
corresponds to the preset that you want to use. For example, press
the [A] button eight times to set Preset 8. The LED flashes the
number of the preset used.
3. Press and release the [MODE] button to save the current setting.
Operation
Dual Technology
When both PIR and acoustic detection are used, the following logic is
used:
• When the space is vacant, PIR detection and manual control can
switch the state to occupied.
• When the space is occupied, PIR, acoustic detection, and manual
control can reset the vacancy timeout.
• When occupancy in the space has only been triggered by acoustic
detection for 60 minutes, acoustic detection is disabled until the
next PIR detection event.
PIR (only) Detection
When acoustic detection is disabled (DIP switch 6 set to On), the
following logic is used:
• When the space is vacant, PIR detection and manual control can
switch the state to occupied.
• When the space is occupied, PIR detection and manual control can
reset the vacancy timeout.
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; see
). 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.
Grace Period
The sensor features a 30 second grace period after a vacancy timeout
occurs. During this grace period, if the sensor detects occupancy, it will
turn on or restore the previous lighting condition.
Auto Vacancy Timeout
The “Auto” vacancy timeout setting varies the vacancy timeout between
5 and 30 minutes depending on how often it identifies an occupancy
trigger after a vacancy timeout occurs (during the grace period).
