2.2 Intended use
The flex device combinations for movement detectors are used for switching lighting systems in
dependence of brightness and/or movement. It is designed only for interior areas of buildings
and for wall mounting.
The flex device combinations for movement detectors are not suitable for use as an intrusion or
attack alarm since they lack the required security against sabotage in accordance with the

2.5 Safety instructions
Danger - Electric voltage!
Electric voltage! Risk of death and fire due to electric voltage of 100 … 240 V.
Dangerous currents flow through the body when coming into direct or indirect
contact with live components. This can result in electric shock, burns or even
death.
■Work on the 100 … 240 V supply system may only be performed by
authorised and qualified electricians.
■Disconnect the mains power supply before installation / disassembly.
■Never use the device with damaged connecting cables.
■Do not open covers firmly bolted to the housing of the device.
■Use the device only in a technically faultless state.
■Do not make changes to or perform repairs on the device, on its components
or its accessories.
■Keep the device away from water and wet surroundings.
Caution! - Risk of damaging the device due to external factors!
Moisture and contamination can damage the device.
■Protect the device against humidity, dirt and damage during transport,
storage and operation.

4 Overview
4.1 Design lines
This system manual serves for the technical planning of the simple to complex installations of
movement detectors.
The different design lines of the device groups and devices are not listed in this system manual.
The sections for the design line are marked with a "xxx" at the article numbers of the respective
devices.
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.
4.2 Basic principles
Information about basic functions and principles of operation of the devices are available at
Chapter 12 “Information about planning and application“ on page 49.

5 Overview of product range
5.1 Applications
Lighting systems can be controlled intelligently, according to need, with movement detectors.
The choice of the right device depends on the type of rooms, the size of the area to be
monitored, the installation situation and the type of movement to be detected. In rooms that are
entered by people, other detection situations than, for example, in stairwells are used.
In addition to the detection situations, the devices are different with regard to the operating
technology.
5.2 Compatibility
The movement detectors from product group ABB flexTronics are not compatible with
movement detectors of the following series:
■Busch-Watchdog 180 flush-mounted standard sensor
■Busch-Watchdog 180 flush-mounted sensor, Comfort II
■Flush-mounted inserts with the 6-pin round interface, such as:
■Busch-Universal relay switch insert 6401 U-102-500
■Busch-Universal 2-gang 1-way insert 6402 U-500
■Busch-Watchdog MOS FET insert 6804 U-101-500
■Busch-Watchdog Relay insert 6812 U-101-500
■Busch-Watchdog Extension unit insert 6805 U-50x
The movement detectors from product group ABB flexTronics can therefore not be integrated
into installations with movement detectors of the following series:
■Busch-Watchdog 180 flush-mounted standard sensor
■Busch-Watchdog 180 flush-mounted sensor, Comfort II

5.3 ABB flexTronics Movement detectors
Fig. 1: ABB flexTronics Movement detector
ABB flexTronics devices have a modular design. The sensor and the actuator are isolated from
each other.
– The desired function of the mounted movement detector is determined from the combination
of the actuator and sensor used.
– The mounted movement detector is operated by means of the sensor.
The interfaces between the sensors and the actuators are standardised.
– One sensor can be combined with all actuators.
– One actuator can be combined with all sensors.
In this way, all available actuators, sensors, switches, etc. of the ABB flexTronics devices can
be combined with each other in a purely physical manner. This does not always makes sense,
however.
This product manual provides information about the useful combinations for the implementation
of movement detectors for light control.
