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 5 minutes
(indicated by dip switches 3 & 4 set to “Off”). 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 vacancy timeout between 5 and 30
minutes depending on how often it see’s an occupancy trigger after a vacancy
timeout occurs (during the grace period).
Lens Masking
Lens masks are provided in the packaging for your convenience, used to block
a section of the lens from detecting occupancy.
PIR Detection
The PIR detection automatically adjusts its sensitivity to eliminate nuisance
tripping.
When the sensor powers on, the red PIR LED illuminates “On” for
approximately 60 seconds to identify “Power Up” state. Sensor configuration is
not allowed. During this time, no events are triggered.
Step 1: As needed, trim the lens mask to fit the
desired area to be blocked.
Step 2: Gently press down on the sensor lens,
which will give only slightly, and insert
the lens mask.
Step 3: Rotate the lens mask around the
dome to block the
required area from
occupancy sensing.
