Ceiling installation
A ceiling installation unit 73 A is available for simplified
ceiling installation of the presence detector (see accessories).
This also ensures cord grip and contact protection. The instal-
lation diameter is 72 mm (drill diameter 73 mm).
Surface-mount installation
A back box 110A is available for surface mount installation
(see accessories).
7. Switching
The presence detectors can be combined as master and slave:
master in individual switching, master in parallel switching,
master-slave parallel switching.
Several push buttons can connected to one control input.
Illuminated push buttons can only be used with neutral con-
ductor connection.
Individual switching
In individual switching, the presence detector as master
detects presence and brightness and controls lighting.
L’
Master/slave parallel switching
If the detection area covered by one presence detector is
insufficient (larger rooms), then up to 10 detectors can be
operated in parallel by connecting P terminals. In the process,
presence detection is performed by all detectors together. The
master measures the brightness, operates the push buttons
and controls the lighting. All other detectors are used as
slaves. They only provide presence information.

•
Light measurement only with the master
•
Parameters are only set on the master
•
Switch up to 10 detectors in parallel
•
Use the phase with the same phase for all detectors.
Master: theRonda P360 -100 M
Slave: theRonda P360 Slave
Master/master parallel switching (for several
lighting groups)
Several masters can be used in parallel switching setup. Each
master controls its lighting group according to its own bright-
ness measurements. Delay times and brightness switching
values are set individually on each master. Presence continues
to be detected by all the detectors.
