Dual Tech Occupancy Sensor
Preset
While in Basic configuration mode (DIP switch 2 set to Off), use the [MODE]
and Auxiliary [A] buttons to program the preset that is activated with an
occupancy detected state change. By default, this is Preset 1. When vacancy is
detected, the default action event is Off.
Follow these steps to configure the preset for your sensor:
1. Access the sensor electronics and press and hold the [MODE] button
for three seconds to enter "Program Mode." The Mode LED lights in
amber to indicate the sensor is in Program Mode and the Auxiliary LED
flashes to indicate the preset number controlled by the occupancy
action. By default, this is Preset 1, therefore the LED will flash one time,
pause two seconds and flash again.
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
page 7 ). When the vacancy timeout ends, the grace period begins.
