Vacancy Sensor
Operation
When the space is vacant, 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
on page 8
). 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).
