Heat radiation too high.
Destruction of the sensors.
Align the device so that no direct sunshine hits the sensor window.
Do not place the device in the sun.
3: Installation laterally to the direction of movement
Selecting the installation location
At an installation height of 2.4 m ( 2), the optimum range of the motion detector is achieved
transversely to the direction of movement ( 3).
The range is reduced in the case of:
- The land slopes upwards away from the motion detector
- Internal housing in middle or lower lock ( 6)
- Low temperature difference
- Installation height less than 2.4 m
- Effects of weather, e.g. rain, fog or snow
The range is increased in the case of:
- The land slopes downwards away from the motion detector
- High temperature difference
- Installation height greater than 2.4 m
o
Select a vibration-free installation location; vibrations can lead to unwanted switching.
o
Avoid interference sources in the detection area. Interference sources, e.g. heaters,
ventilation, air conditioners, or cooling light bulbs can lead to unwanted switching.
o
Take direction of motion into account.
o
Determine installation height.
i
To achieve a rapid response from the motion detector on leaving the building, install the
device at a height of less than 2.4 m, centrally above the door.
Installing the motion detector
o
Slacken central screw (3) ( 1).
o
Remove the housing cover.
