Surface-Mount PIR Switching Sensor
(SS-PIR-SW-01)
The SS-PIR-SW-01 is a PIR-triggered switch suitable for mounting onto a back box or directly onto a solid surface. It allows
simple selection of presence or absence detection to control both lighting and nonlighting loads.
Configurable for any room occupancy style, it switches on the connected load if the area is occupied and the illuminance is
lower than the specified level (with the photocell activated). Similarly, it switches off the load if the area is unoccupied for the
set time.
In absence mode, the unit can also be operated from a mains-rated retractive wall switch.

Operation
Presence Mode (Default Mode)
Out of the box, the time-out adjuster is set to 10 s, and the illuminance threshold adjuster is set to maximum (photocell
inactive). With the illuminance threshold adjuster set to maximum, the sensor will always switch on the connected load
when movement is detected. There are nine time periods available from the time-out adjuster (from 10 s to 40 min).
Multiple sensors can be connected to the same load in order to extend the detection zone (see 'Multiple sensors' on
page 2).
Absence Mode
With the mode selector set to absence detection mode, pressing a retractive switch connected to the sensor will switch
on the connected load. Then, if no presence is detected for the selected time period, or if the retractive switch is pressed
shortly, the load will be switched off
