Response Once The Batteries Have Been In; Walking Test; Replacing Batteries - HomeMatic HM-Sen-MDIR-O-2 Manual

• Turn the cover of the wireless infrared motion
detector outdoor anti-clockwise and lift if off.
• Insert the three LR6 (AA) mignon batteries
supplied with the device into the battery compart-
ment (E), ensuring that the polarity is correct
(see the polarity markings).
• Push the cover down onto the battery compart-
ment (E) and turn it clockwise until it locks into
place.
6.2 Response once the batteries have been
inserted
Once the batteries have been inserted, initialisation is
performed. The LED test display will indicate that ini-
tialisation is complete: the LED will light up red, green
and orange in that order, for half a second each.
The device LED is located in the PIR lens (A) and is
36
visible through the lens.
If an error occurs, this is indicated by the LED flashing
red. The device LED will then light up orange for a
further 30 seconds, which is the time you must wait for
the motion detector to become ready for operation.
Once the batteries have been inserted, it will
take around 30 seconds before the device will
be ready for operation. No motion will be
detected during this time.

6.3 Walking test

For up to 10 minutes after the batteries have been
inserted, the device LED will indicate a detected move-
ment by lighting up red briefly.
This allows the detection range and sensitivity to be
tested at the sensor directly (the latter can only be
checked if it has previously been registered and confi-
gured via the central control unit).

6.4 Replacing batteries

If the equipment being controlled does not respond
when the wireless motion detector is tripped and there
is no remediable communication fault (equipment
being controlled disconnected from mains, receiver
batteries flat), follow the instructions of Chapter 6.1 to
