Selecting installation location
Select a vibration-free installation location. Vibrations can lead to unwanted switching.
To achieve optimum range, choose an installation location that is tangential to the direc-
tion of motion.
Avoid interference sources in the detection area. Interference sources can trigger the mo-
tion detector, e.g. heat sources such as heating units, outlets from ventilation openings or
air conditioners, copiers, printers, coffee machines, draughty doorways, animals etc.
Fitting the cover
Connecting and mounting the FM insert properly (see flush-mounted insert instructions).
Fit the cover with frame on the flush-mounted insert.
Expanding the detection field
To expand the detection field, connect a 3-wire extension with motion detector cover. The main
device also evaluates signals of the extension and, if necessary, switches the lighting on.
Limiting the detection field motion detector cover 1.10 m
The detection field can be limited using a panel (Figure 9) and (Figure 10).
