In all these cases it is obligatory to replace the combined detector.
Activity indicator
A very faint and brief green flashing of the activity indicator shows that
the module is functioning correctly. This indicator is only visible when
the base is removed.
Channel selectors
The channel selection switches of the module are set to channel 0 by
default. Normally this setting does not need not be changed.
However, if separate detector groups are to be operated within the
same building, the detectors can be set to different radio channels.
To do this, remove the base of the detector, unscrew and remove the
module cover (image on page 40) and set both channel selection swit-
ches to the desired channel number. All devices within a detector
group must be set to the same channel in the same way.
Changing this setting has no effect on the signolux receiver units.
