Operating the Sensor
The IS 140-2 motion detector offers flexible adjustments to suit various environmental conditions and detection requirements.
Adjusting Detection Zone and Range
The sensor has a 140° angle of coverage and a maximum range of 14 meters. The optical system can be swiveled through 180° horizontally and tilted through 90° vertically to precisely define the detection area. Shrouds are provided to further customize and limit the detection zone, preventing unwanted triggers.

Setting Time and Luminosity
The sensor features adjustable settings for light sensitivity (luminosity) and the duration the connected light remains on after detection (time). These adjustments are typically made via dials located on the sensor unit.

Figure 6: Side view of the sensor revealing the adjustment dials for setting time and luminosity thresholds.
- Luminosity (Lux): Adjusts the ambient light level at which the sensor becomes active. The response value luminosity is 2 to 2000 lx. Turn the dial towards the sun icon for activation in brighter conditions, or towards the moon icon for activation in darker conditions.
- Time (Duration): Sets how long the connected light stays on after motion is detected. The adjustable range is from 8 seconds to 35 minutes.
