2. Safety warnings
Attention: Electrical equipment must be installed and fitted by
qualified electricians only.
Non-observance of the installation instructions may damage the
device and cause fire or other hazards.
3. Presence detector principles
A presence detector belongs to the group of passive infra-red detectors
(PIR) exactly like movement detectors or detectors for alarm
These devices can be distinguished by their internal structure, signal
detection and signal evaluation which make them suitable for different
applications:
• After detecting movements, a movement detector switches the light
on dependent on brightness and off in dependent of brightness when
no movements are detected anymore.
• A movement detector for alarm systems signals a movement (pulse)
to a central alarm station independent of brightness. The number of
pulses transmitted within a time slot can often be freely selected. The
field of detection is limited to narrower angles (90° and in most cases
even less).
• A presence detector is designed to switch on the light dependent on
brightness when movements are detected and to switch it off when it
is no longer needed. This is the case if it is bright enough without
artificial lighting or when no one is present anymore. This means that
the ‘presence’ of a person is detected depending on a preset
brightness level.
These PIR detectors differ mainly in the design of the Fresnel lense
installed, their adjustment with regard to ambient conditions, the type of
fitting and the properties of the movement or brightness signal.
A presence detector is exclusively installed under the ceiling of a room
and monitors the room surface below. It works with a passive infra-red
sensor (PIR) and responds to thermal movements triggered by persons,
animals or objects.
4. Function of presence detector ‘Standard’
Function presence Standard
The presence detector ‘Standard’ is used for the detection of presence
(presence detector mode) and for the detection of movements (ceiling
detector mode) in rooms.
Both modes of operation offer 2 independently programmable output
channels.
The respective mode of operation (ceiling detector or presence detector)
is programmed for the presence detector ‘Standard’ model with the ETS
software.
Subsequent switching between the operating modes is not possible. A
change of the mode of operation requires reprogramming of the device.
L The presence detector ‘Standard’ can only be used as a stand-alone
unit. It is not possible to use several presence detectors ‘Standard’ in

the same room to enlarge the detection range. The detectors would
interfere with one another.
Function of presence detector ‘Universal’
The instabus presence detector ‘Universal’ can be operated in three
different modes::
• ceiling detector mode
• presence detector mode
• signalling mode
The modes are selected when the device is programmmed with the ETS
software. The device can be programmed so that only one mode is active
(mono operation) or that the device can be switched between two preset
modes via the instabus EIB (alternative operation, e.g day-time presence
mode and night-time signalling mode).
Both modes of operation offer two output channels with independent
parameter programming.
Depending on the type of application, the presence detector
‘Universal’ can be used as individual unit, main unit or
extension unit. The operation as main unit and as extension
unit permits enlarging the zone of detection. The presence
detector ‘Universal’ can also be used in combination with
flushmounted automatic switches from JUNG in a master-slave
configuration. For brightness-independent activation it is also
possible to use a touch sensor as extension unit.
Description of the modes of operation with predefined parameters
Ceiling detector moder
In the ceiling detector mode, the device detects movements and
transmits the programmed telegram representing the beginning of
detection, when the measured brightness is below the preset brightness
value. The device is now operational independent of brightness. If no
further movements are detected, the device transmits the programmed
telegram representing the end of detection when the preset overall
transmit delay has elapsed.
Presence detector mode
In the presence detector mode, the device detects the presence of a
person and transmits the programmed telegram representing the
beginning of detection, when the measured brightness is below the
preset brightness value.
If no presence is detected anymore and if the preset overall transmit
delay has elapsed or if the preset brightness value has been exceeded
for at least 10 minutes by the double, the presence detector transmits the
programmed telegram representing the end of detection.
The functional difference with regard to the ceiling detector mode lies...
a) in the processing of the movement signal Contrary to the ceiling
detector mode, a presence is detected only after several successive
movement pulses have been received.
b) in the processing of the brightness signal The presettable brightness
range to be monitored for the brightness threshold value is larger than in

the ceiling detector mode. It is only after twice the value of the preset
brightness threshold (switch-off brightness) has been exceeded that the
programmed telegram representing the end of detection is transmit ted
after ca. 10 minutes even if someone is still present. This switch-off
brightness can be changed with a correction factor in the programmed
parameters.
c) in the evaluation of combined movement and brightness signals The
light is switched on when a person is present and when, at the same
time, the brightness falls below the preset brightness threshold. The light
is switched off when nobody is present or when the ambient brightness
without artificial lighting is high enough.
Signalling mode (only in the ‘Universal’ version)
In this mode with a signalling function, the device detects movement
pulses independent of brightness and counts them with a pulse counter.
If – within a fixed time-span (standard value: 10 seconds) – at least the
fixed number of pulses (standard value: 4) have passed the counting
gate, the programmed telegram representing the beginning of detction
will be transmitted.
When no movement pulses are detected anymore, the presence detector
transmits the programmed telegram representing the end of detection
after the standard transmit delay of 10 seconds has elapsed. In the
signalling mode, the presence detector ‘Universal’ is always operated as
an individual unit.
Further product features:
• Alarm function: When someone tries to remove the device, the
detector can be made to transmit a programmed telegram.
• Teach-in function: The switch-on threshold within the brightness
range can be changed by means of an instabus EIB telegram.
A more detailed description of the functions is given in the instabus
documentation for these products.
5. Fitting
The presence detector must be installed together with an instabus bus
coupler only under the ceiling. The fitting and connection instructions for
bus couplers are set out in the technical documentation of this product.
Plug the presence detector on the base without exerting pressure on the
lens. The electrical contact is established via the user interface (AST).

Sources of interference:
Do not install the device in the direct vicinity of heat sources as, for
instance, lamps (illustration on the left). Cooling of the lamp might be
interpreted by the PIR sensor as a thermal change and trigger another
detection cycle. The presence detector must not be installed close to
fans, radiators or ventilation ducts either. Draughts (also from open
windows) might be detected as movements and cause retriggering of the
device. If necessary, the detecting range must be confined by means of
the snap-on mask supplied with the device (see also ‘Snap-on mask’).
Remember that the detection field is restricted by obstacles such as
furniture, columns, etc. Movements behind obstacles cannot be detected.
The brightness sensor (1) should be installed on the side away from the
window to avoid the undesired influence of scattered light. Install the
presence detector in a place free from vibrations, since the device may
also be triggered by movements of the sensor.
Important: Avoid direct sunlight into the sensor window. The sensors
might be irreparably damaged by the high thermal energy.
6. Adjustment
After fitting and programming with the ETS, the range settings defined in
the software may be modified with the help of potentiometers provided on
the device itself, if this function is enabled in the software.
To adjust brightness, on-time and sensitivity, withdraw first the decorative
ring (4) from the presence detector. The potentiometers are then
accessible.(see illustration on the left).

(1) On-time: time
The software-defined ‘supplementary transmit delay’ corresponds to the
center position of the potentiometer and can be changed by +/- 50%,
e.g.. 120 s +/- 60 s.
(2) Brightness: lux
Fine-tuning of the software-defined twilight threshold. The setting range
depends on the mode of operation selected and comprises the full range
of twilight values, e.g. 300 – 600 lux.
(3) Sensitivity: sens
Stepless reduction of the maximum reach from 100% down to ca. 20%
independent of the software settings.
Put the decorative ring (4) back in place after the adjustment. The nose of
the brightness sensor must engage in the opening in the decorative ring
(4).
L The lower the number of movements expected in the controlled area
the longer should be the supplementary transmit delay to prevent
premature switching off of the lighting.

Adjustment information
If the software-defined values are not precise enough, they can be
adapted within a limited range with the help of the lux and time
potentiometers, if this function is enabled in the software. If the necessary
readjustment exceeds the predefined range, the parameters must be
corrected and the device reprogrammed thereafter.
Load remains on even with strong external light (e.g. bright sunlight).

Present brightness value too high Turn lux potentiometer towards ‘Moon’
Load not switched when movement is detected on in spite of
insufficient brightness.
Cause Remedial action
Present brightness value too low Turn lux potentiometer towards ‘Sun’
Load switched off although persons are present and lighting is insufficient.
Cause Remedial action
Preset time too short Select longer time with the time

Cause Remedial action
After shutoof, the ambient brightness falls below the
preset minimum brightness, device switches on again
immediately when movement is detected.
Turn lux potentiometer by a small amount in the
direction of ‘Sun’
Additional information on the measurement of brightness values:
The brightness values detected by the presence detector depend on
several conditions. The reflexion of light by the surface directly under the
presence detector is of decisive importance. Bright surfaces such as
white paper on the desktop reflects of course much more light than a dark
carpet. It may therefore be necessary to change the setting of a presence
detector when the bright desktop below is moved to another place in the
room and when there is now a dark carpet under the detector instead.

7. Field of detection
The presence detector has a detection range of 360°.
The PIR sensor system works with 6 detection levels and 80 lenses.
The field is ca. 5 m in diameter at desktop height (ca. 80 cm). The field
diameter on the floor is ca. 8 m.
These values are referred to an installation under the ceiling at a height
of 2.5 m and tangential, i.e. lateral movement.

Important:
In the event of movements directed straight towards the presence
detector, a reduction of the detection range must be expected. In
this case, detection in the outer 4m range is not ensured.
If a person approaches the presence detector quickly, there may be
the impression of a reduced range. In this respect, attention must
also be paid to possible switch-on delays of the lamps used.
This aspect must be observed especially in such applications where
the device is used as a ceiling detector.
A significant increase of the installation height reduces the
sensitivity of the device to detect movements.
8. Snap-on mask
To protect the system of lenses, the device is delivered with the
transparent snap-on mask already in place. To obtain maximum detection
range, the mask must be removed.
The snap-on mask supplied can be used to blank out undesired zones of
detection or sources of interference (see chapters Fitting, Sources of
interference) by limiting the detection field.
Determine the zones which are to be excluded from detection.
Cut out the mask after removal from the sensor along the marked lines in
such a way that the mask blanks the zones determined above.
Cutting out the mask changes the diameter of the detection field on the
floor as follows: Zones I to III see illustration on the left.

no cut-out zone I: ∅ ca. 2,20 m
zone II cut out: ∅ ca. 4,00 m
zone II+III cut out: ∅ ca. 6,00 m

The figures are referred to an installation height of ca. 2.50 m.
