Surface-Mount PIR Switching Sensor: Installation Guide
Setup
Presence Mode
Auto on, auto off via time-out settings (no manual wall switch control). Multiple sensors can be connected to the same load
in order to extend the detection zone (see figure in section ‘Multiple sensors’ on page 2). When used in conjunctions with
illuminance settings, the load will only switch on if the detected light levels are below the minimum level set on the illuminance
threshold adjuster.
Absence Mode
Manual on via wall switch, auto off via time-out settings or manual off via wall switch. Single sensors only. Not for use with
multiple sensors in parallel.
Illuminance Setup
Notes: It is best to adjust the illuminance setting when the ambient light level is at the required minimum level.
For loads that should switch on regardless of ambient light levels, set the illuminance setting to maximum (photocell
inactive).
1. Set the illuminance setting to minimum and wait for the load to switch off.
2. Slowly increase the illuminance setting while waving your hand below the sensor until the connected load switches on.
