9. Presence detector system (Master/Slave)
If larger areas are to be monitored, it is also possible
to use several presence detectors together in the
same system. In the presence detector system one
presence detector must be specified as the master
unit whereas all other detectors are used as slave
units.
Reference brightness value
The desired reference brightness is adjusted on the
master unit and is then valid for the whole system.
In all other presence detectors (slaves), the reference
brightness must be set to minimum (moon symbol
(fig. 9.).
Shut-off delays
The shut-off delay can be adjusted separately on all
presence detectors used. If an actuator is switched by
a presence detector, the shut-off delay of this device
starts running.

Programming the presence detectors
When programming the presence detectors into the
radio-control receiver (cf. section 2 „Programming a
detector into a radio-control receiver“) make sure the
presence detector specified as master unit is pro-
grammed first. The brightness reference control must
therefore not be set to minimum (moon symbol) since
the detector would otherwise be identified as slave,
which means that it cannot be programmed as the
first unit into an actuator.
The slave detectors can only be programmed thereaf-
ter. In the slaves, the brightness reference must be
set to minimum (moon symbol).
If a master has already been programmed, any fur-
ther programming of a master overwrites the previous
one, i.e. only one unit can be stored as master detec-
tor.
10. LED and LowBatt indicator
The LED behind the sensor window (fig. 10.
c
) flash-
es up briefly 3 times during each transmission.
In the movement test mode, the LED flashes 6 times
during each transmission.
If the LED flashes ca. 10 times during a transmission,
the batteries are almost empty (LowBatt) and should
be replaced (cf. section 2 „Inserting/replacing the bat-
teries“).
