1. System information

This unit is a product of the instabus- EIB-System and corresponds to the
EIBA Guidelines. Detailed technical knowledge acquired in instabus
training courses is a prerequisite for the understanding of the system.
The functions of the device are softwaredependent. Detailed information
on the software and the functions implemented and the software itself are
available from the manufacturer’s product data bank.

Planning, installation and commissioning of the device are effected with
the help of EIBA-certified software. For the productdatabase and
technical descriptions please refer to the internet at www.jung.de offering
up-to-date information.

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).
