Other notes on operation

9.1 Sensitivity

• If it is operated without the central control unit,
every sensor pulse causes the motion detector to
trip.
• If the central control unit is used, the response
according to the intensity of motion can be set on
the unit.
Examples of use:
- Audible signal: insensitive, e.g. 3 pulses per
period
- Visual signal: sensitive, e.g. 1 – 2 pulses per
period

10 Resetting to the initial state

• Press and hold the teach-in button on the wire-
less motion detector for at least four seconds.
The device LED starts to slowly flash red.
• To reset the device, now press and hold the
teach-in button for at least another four seconds.
The LED will now start to flash red faster.
• Release the teach-in button to complete the
reset procedure; the LED briefly lights up red,
green and orange in sequence to confirm that
48
the reset has been successful.
Possible error messages:
(This error can only occur if you have a central control
unit to which you have taught-in the device.) If the LED
does not start to flash when the button has been held
down for five seconds, but lights up continuously in-
stead, the device cannot be reset. In this case, coding
is activated using a system security key that differs
from the one supplied with the product. To reset the
sensor, you will have to use the configuration software
for resetting the central control unit. The procedure to
follow is described in the manual for the central control
unit software.
