Radio-Control Presence Detector
1. Function
The radio-control presence detector (fig. 1.a) permits
to achieve optimal energy savings by controlling the
illumination of a room depending on the presence of
persons.
1.a)
The detector is equipped with a passive infrared sensor (PIR) and responds to thermal movements triggered by persons, animals or objects. The detector
transmits a radio data telegram which can be processed by all radio-controlled dimming and switching
actuators from release R2 onwards (see. identification on actuator).
The presence detector activates a programmed radio-control actuator whenever the ambient brightness
drops below an adjustable reference brightness and
whenever movements are detected. The actuator
then controls the light intensity depending on the reference brightness.
Order no.: 0318 02 / 0318 04
For monitoring of large areas, several presence detectors can be used in common in the same system.
In this case, one presence detector works as the master unit (main unit) whereas all other presence detectors work as slave units (extension units).
Description
The radio presence detector consists of:
c sensor window with LED
d ornamental ring
e baseplate
f pushbutton
Under ornamental ring d, the detector has 3 controls
for the setting of:
g sensitivity
h shut-off delay
i brightness reference
1.b)
The light control remains activated as long as the presence detector detects movements.
If no movements are detected anymore, the detector
switches off after the preset shut-off delay. The detector is equally switched off when the upper brightness
limit is exceeded. .
i
If the user wants the light control to be active immediately after a person enters the monitored surface,
it is recommended to switch on the light control by
hand (cf. chapter 6.2 and 7.2) as it will otherwise take
a few seconds until the light control is activated by
the presence detector.
The reason for this is that - to avoid false triggering the detector’s sensitivity is initially reduced as compared to that of a movement detector.

Please note that the number of radio presence detectors to be used inside a radio-control zone (zone in which
radio telegrams can be exchanged between subscribers) is limited. As all these devices react in the same way
to the same ambient conditions as, for instance, a sudden rise of the outside brightness level, and as they will
then begin transmitting telegrams, the probability of the telegrams interfering with one another and thus causing malfunctions is considerably increased.
Depending on ambient conditions, a number of more than 8 radio-control presence detectors may already be
sufficient to cause malfunctions.

2. Fitting and start-up
Safety instructions
Attention: Electrical equipment must be installed and fitted by qualified electricians only.
Place of fitting
The presence detector is fitted under the room ceiling
and monitors the working surface below (fig. 2.a).
Fig. 2.b: the actual brightness measured at the detector d is composed of reflected artificial light c and
daylight e and depends on the reflection properties of
the working surface f.
Install the presence detector free from vibrations and
not in the immediate vicinity of heat sources (e.g.
lamps, radiators), fans or ventilation ducts. Lamps
cooling down after operation or draughts (e.g. caused
by open windows) might be detected and lead to undesired switching.
Fitting
2.a)
2.b)
Avoid direct sunlight into the sensor window. The sensors might otherwise be irreparably damaged.
If needed, the detection field can be confined by
means of the mask supplied with the device (cf. section 3).
Attach the presence detector to the baseplate only after having installed the batteries and programmed the
presence detector into a radio-control receiver.
To install the presence detector proceed as follows:
1. Fasten the baseplate to the room ceiling using the
screws supplied (fig. 2.c c).
2. Turn the presence detector on the baseplate approx. 45° counterclockwise until it is heard to engage.

Batteries
Radio-Control Presence Detector
Installation Instructions
The radio-control presence detector operates on 4 alkaline micro batteries (LR 03) (not included in the
scope of supply). Batteries of the carbon-zinc type
(R 03) must not be used.
Safety and disposal instructions
Attention: Keep batteries away from children.
Remove used batteries immediately and discard
without polluting the environment.
Replace battery by identical or equivalent types
only.
Inserting / replacing the batteries
1. Detach the presence detector from the baseplate
by turning the device approx. 45° clockwise on the
baseplate (fig. 2.d).
2. Replace the old batteries located at the back of the
housing. Wait ca. 2 minutes (capacitor discharge
time) before inserting the new ones paying attention to correct polarity (fig. 2.e).
3. Refit the presence detector on the baseplate by
turning the device approx. 45° counter-clockwise
until it is heard to engage
4. After insertion of the batteries, the device starts
transmitting programming telegrams for ca. 30
seconds.
To avoid undesired programming make sure that
none of the actuators is in the programming mode
during this time.
2.d)
2.e)
Programming a detector into a radio-control
receiver
For light control applications, the presence detector
must be programmed into only one radio-control receiver. The programming information is stored in the
radio-control receiver only.
During programming of a radio-control presence detector, the sensitivity of the radio-control receivers is
reduced to approx. 5 m. The distance between the receiver and the radiocontrol presence detector should
therefore be not less than 0.5 m and not more than 5
m.
Programming procedure
1. When programming the first presence detector into
the radiocontrol receiver make sure the brightness
control (fig. 2.f i) does not point to the „Moon“
symbol. A presence detector with this setting will
be identified as a slave unit and can therefore not
be programmed as first unit into a radio-control receiver.
For programming of a presence detector system
(master/slave) please read also section 9.
2. Remove the battery for approx. 2 minutes from the
presence detector (capacitor discharge time).
3. Switch the radio-control receiver into the programming mode (see „Radio-control receiver“ operating
instructions).
4. Put the battery back in place. The presence detector now starts transmitting special programming information telegrams for approx. 30 seconds. The
receiver confirms the programming cycle (see „Radio-control receiver“ operating instructions).
5. Switch the radio-control receiver back to the operating mode (see „Radio-control receiver“ operating
instructions).

The radio-control presence detector cannot be operated together with a radio-control detector. For this
reason, it is essential that this transmitter has not
been programmed into the corresponding receiver
before the presence detector is programmed. If this
is the case, it must be deleted beforehand.
Programming of the presence detector is otherwise
not possible and the radio-control receiver remains
in the programming mode.

3. Field of detection and snap-on mask
Deleting a detector in the radiocontrol receiver
An already programmed presence detector can be
deleted by starting a new programming cycle in the
radio-control receiver.
The presence detector has a detection field of 360°.
The PIR sensors are arranged in 6 detection levels
with 80 lenses.
The detection range is ca. 5 m in diameter at desk
height (ca. 80 cm).
The diameter of the detection field at floor level is ca.
8 m.
These values are valid for installation under the ceiling and a fitting height of 2.5 m.
For fitting heights above 2.5 m, the detection field increases whereas the detection density and the sensitivity are reduced.
Snap-on mask
The snap-on mask supplied with the detector can be
used to blank out undesired zones of detection.
The mask is snapped onto the sensor window. Cut
out the mask only along the marked lines (fig. 3.c).
The following data are referred to a fitting height of ca.
2.50 m. In this case, the detection field on the floor
has a diameter of ca. 8.00 m.
3.c)
Cutting out the mask changes the diameter of the detection field on the floor as follows:
Full mask without cutouts, sector I: Ø ca. 2.20 m
3.b)
Radio-Control Presence Detector 7/07 Page 4 of 15
Sector II cut out: Ø ca. 4.00 m
Sectors II and III cut out: Ø ca. 6.00 m
Without mask: Ø ca. 8.00 m
The size of the detection field can be checked when
the detector works in the movement test mode.

4. Settings
To vary the brightness, the shut-off delay and the sensitivity start by removing the ornamental ring (fig. 4.a
d) from the presence detector to gain access to the
controls.
4.a)
g Sensitivity „sens“
The potentiometer permits adjusting the sensitivity of
the sensor between maximum and minimum.
When the sensitivity control is at minimum, the presence detector does not respond to movements.
h Shut-off delay „time“
The potentiometer permits adjustment of the shut-off
delay for automatic operation in fine steps between
approx. 2 minutes and 1 hour. The center position
corresponds to 15 minutes.
Recommendation:
For smaller rooms, a shut-off delay of approx. 5 minutes is recommended.
For larger rooms, a longer delay should be chosen.
i Reference brightness „lux“
The potentiometer permits the adjustment of reference brightness values in fine steps between approx.
3 lux (moon symbol) to approx. 2000 lux (sun symbol). The center position corresponds to approx. 100
lux. The setting is taken over by the radio actuator
only after activation of the „light control test mode“.
After performing the setting put the ornamental ring
back in place. The protruding light sensor must fit into
the corresponding recession in the ornamental ring.
5. Setmodes
5.1 Light-control test mode
The light control test mode is used to preset the reference brightness of the presence detector. Fine tuning
can be done later by remote control when suitable radio-control transmitters have been programmed. For
dimming actuators refer to section 6.5 and for switching actuators to section 7.5.
In this mode, the detector does not detect movements, but permits fast adjustment of the actual/reference brightness values (light control).
The reference brightness preset on the detector is
transmitted to and stored in the radio-control receiver.
The radio-control receiver compares the actual brightness value transmitted to the reference brightness
stored and performs a light control.
Setting the reference brightness:
Important
The presence detector must have been programmed
beforehand into the radio-control receiver.
1. Depress button (5.a f) for at least 1 second. LED
(5.a c) first flashes up 10 times in a fast sequence
and then periodically every 5 seconds. The presence detector is now for approx. 5 minutes in the
light-control test mode.
