1 Overview
1.1 Design lines
This system manual serves for the technical planning of the simple to complex installations.
The different design lines (with the respective special colours and shapes of the devices) are
not listed in this system manual.
Please obtain the desired current design versions and the corresponding complete article
numbers as well as the order numbers from the respective product catalogues or the online
catalogue at https://busch-jaeger-catalogue.com.
1.2 Basic principles
Information about basic functions and principles of operation of the devices are available at
Chapter 4 “Information about planning and application“ on page 53.

2 Overview of product range
2.1 Applications
Lighting systems and also heating, air-conditioning and ventilation systems (also referred to as
HVAC in the following) can be controlled intelligently, according to need, with presence
detectors.
The choice of the right unit depends on the height of the ceiling, the size of the area to be
monitored, the installation situation and the type of movement to be detected.
Detection situations in corridors through which people move are totally different to offices in
which sometimes only a finger moves across a keyboard. If a person works exclusively at a
computer, only minimal movement is to be expected. Here detection by the watchdog needs to
be especially fine and precise. In gymnasiums on the other hand, where there is a lot of action,
other factors are involved: Here the watchdog must accurately detect movement from a great
height and at the same time be protected by a protective basket against damage. In classes
and conference rooms a semi-automatic unit will suffice. Here, in case of presentations with a
beamer, the lights can be switched off manually via a button or a remote control. Also operation
via Bluetooth®is possible for the respective device versions.
In addition to the detection situations, the devices are different with regard to the connection
technology. Aside from the classic connection in 110 to 240 V networks, device versions for
DALI or KNX bus systems are available. KNX devices are dealt with in separate documentation.

flex presence detector sensors and flush-mounted inserts (ABB flexTronics®)
Fig. 2: Busch-Presence detector: flex presence detector sensors and flush-mounted inserts
Busch-Presence detector flex devices have a modular design. The presence detector sensor
(detection lens) and the insert are isolated from each other.
– The desired function of the mounted device is determined from the combination of the insert
and the presence detector sensor used.
– The mounted device is activated with the presence detector sensor.
The interfaces between the presence detector sensor and the inserts are standardised.
– A presence detector sensor can be combined with all inserts.
– One insert can be combined with all presence detector sensors.
In this way, all available inserts and presence detector sensors (detection lenses) of the ABB
flexTronics®devices could be combined with each other in a purely physical manner. This,
however, is not always practical.
– For example, not practical is a blind actuator insert in combination with a presence detector
sensor.
The decor frame is available separately as an accessory and makes individual colour design
possible apart from white and silver.

2.2.2 Monoblock devices
For switching lighting systems that depend on brightness and movement.
For the requirement of controlling a lamp circuit across a large detection range, it is possible to
extend the detection range by means of presence detector extension units. The presence
detector extension units, in dependence of the devices, transmit the information of detection
and brightness to the main unit of the presence detector, which then triggers the appropriate
switching process or function.
In addition to the classic setting options via trimmers, the devices offer additional control
options. Depending on the version used, control can be implemented via infrared remote control
or the ABB Watchdog Remote control app via Bluetooth®.
For devices with a Bluetooth®interface, extended functions can be implemented via the app.
These functions, for example, include a presence simulation, a basic lighting function or an anti-
glare function. Aside from extensive setting and configuration parameters, the electrician is
supported by an error compensation (a PRS that can be switched off and set according to its
sensitivity), a visual test mode and the panel light and heating, air conditioning and ventilation
function. In addition, the semi-automatic mode can be extended with a comfort function.
The following lens forms are available for the devices:
Compact:
For smaller offices, WC facilities, etc.
Universal:
For all popular applications (exception: applications of large heights).
Corridor:
For applications in corridors and hallways.

The sensor switches the light on only when the measured brightness value is
below the value set on the trimmer (5 to 2,000 lux).
When movement is detected, the sensor switches the light on with the set
switch-off delay. The switch-off delay is started anew at every detected
movement.
Setting of daylight
The brightness sensor is ignored at setting of daylight.
The sensor switches the light on by itself exclusively depending on movement.
Setting of test mode
At setting of test mode the switch-off delay amounts to approx. 5 seconds and
the brightness value is set on daylight operation. The detection range can be
checked in test mode.
The test LED flashes at every detected movement and the connected load
switches on for approx. 5 seconds.
To end the test mode, set the desired brightness-value threshold on the device
or press the desired brightness-value threshold on the IR remote control (not
possible with Sky sensors 64754-xxx) due to the large mounting height.

Settings of trimmer left
Setting of switch-off delay (automatic mode)
The switch off delay is adjustable from 1 to 30 minutes or short-time pulse.
The switch-off delay is started or started anew at every detected movement.
When the switch-off delay has expired or the natural light is sufficient to light
up the room, the light switches off again.
The light is switched on again as soon as the brightness drops below the set
value and movement is detected.
Setting of switch-off delay (semi-automatic mode)
The switch off delay is adjustable from 1 to 30 minutes.
After a brief press on the external push-button (connected to the extension unit
input of the flush-mounted insert) the light switches on. The switch-off delay is
now started anew at every detected movement. When the switch-off delay has
expired or the natural light is sufficient to light up the room, the light switches
off.
The light is switched on again with a renewed press of the push-button.
Further behaviour is the same as in automatic mode.
Setting of short-time operation
When this option is set, the used actuator switches on for one second and off
for 9 seconds. This pulsed switching is repeated until movement is detected
and the brightness drops below the set value.
To set the short-time operation via the IR remote control, press button on
IR service remote control 6843.
