Busch-Watchdog 220 MasterLINE KNX premium

Technology of the highest standard. For special tasks.

The Busch-Watchdog not only looks good. It also impresses with its inner quality. High-quality, intelligent technology adds a new dimension to safety. And it gives one a feeling of safety, inside and out. The intelligent Busch-Jaeger movement detectors miss nothing. They respond instantly when needed. For example, they detect immediately when a light is to be switched on or off, and they are a reliable signpost in the dark. These high-quality detection systems guarantee uninterrupted surveillance in all areas. They ensure that your sleep is peaceful, chase away thieves and switch the light on and off when you are on holiday.

Aside from the extensive equipment of the Busch-Watchdog 220 MasterLINE KNX, this movement detector offers additional interesting functions. With its innovative bus-based KNX technique it offers even more convenience with four movement channels. It has a twilight and brightness switch with up to three switching thresholds.

It impresses with ten logic functions to implement complex scenarios. In combination with the Busch-ComfortTouch® the entire house can be individually controlled and monitored - for example, the lights, heating, air-conditioning system, blinds, safety, entertainment and information. And, if desired, also via smartphone or tablet as remote control.

Overview of colours.

The Busch-Watchdog 220 MasterLINE KNX premium is available in the modern colours white and silver metallic.

Detection range.

This movement detector has a detection range of 220°. The coverage is 16 meters to all sides. It has four detection levels without any gaps. Additional features of these innovative devices include ground and rear-field detection, creep zone protection and automatic switch-on of light when stepping out of the door. Second detection level of 1 m towards all sides as well as second switching output (first the path illumination, then main entrance illumination)

Mounting options.

01 Wall mounting.
The classic installation. The Busch-Watchdog movement detectors can be easily and quickly installed. In the classical position on the wall, for example. One of the most frequent installation options.

02 Wall mounting with gradient. Each task is carried out with consummate ease. Busch-Watchdogs are multitalented. Even in complicated installation situations, such as in a building on a hill or with a gradient, the movement detector with the corner adaptor can be installed and adjusted in such a way that it offers the most optimum possibility for detection.

03 Ceiling mounting. All good things come from above. If the Busch-Watchdog is to be installed on the ceiling, there are two versions. From the bottom for a wide detection range. Or with a corner adapter, to be able to position the device correctly.

04 Corner mounting. A Busch-Watchdog accepts all challenges. Thanks to a detection range of up to 280°, even the most difficult surveillance tasks are child's play. In combination with a special corner adapter it is installed on corners of buildings easily and quickly without any difficulty.

Comfortably controlling all functions.

With the practical IR remote control you are always fully in charge of safety and comfort. The settings can be handled easily without a ladder or an electrical installer. For example, brightness switching threshold, presence simulation or continuous light On/Off.
Link to Busch-Remote control IR


  • Ideal for free-standing houses
  • Detection range of 220°, 16 m to all sides
  • With four detection levels
  • The device can be protected against direct dismantling by means of additional screw connections.
  • The retaining hole is compatible with all previous Busch-Watchdog models
  • Important functions such as continuous light On, continuous Off, presence simulation, saving of the brightness switching threshold can be deactivated/activated with the IR remote control without a setting on the device.
  • Remote operation and remote parameterization, further settings/functions can now be disconnected/connected via the IR service remote control.
  • Saving of energy: The time for the forced switch-off depends on the set switch-off delay; however, it is limited to a maximum of 90 minutes.
  • Signalling of detection to make commissioning easier or for diagnostics purposes
  • Cabling is easy to install without clamping
  • No gaps in detection, homogenous, large detection range
  • Floor and rearfield detection
  • As creep zone protection and switch-on when stepping out of the door
  • Automatic range stabilisation. In case of changing outdoor conditions the Busch-Watchdog keeps the range constant.
  • Automatic interference suppression
  • Presence simulation (while on holiday, for example). At the arrival of twilight, continuous light is activated and after approximately 11:30 p.m. the watchdog function.
  • All loads connectable, maximum 3,680 W/VA

Additional functions for the Busch-Watchdog 220 MasterLINE KNX model.

  • With four movement channels for different settings for evening and night
  • One twilight/brightness switch with up to three switching thresholds, excellent detection during twilight
  • Temperature sensor with up to three switching thresholds
  • Ten logic functions to implement complex functions
  • Programmable, coded IR remote control with seven channels
  • Controlling the pump from the terrace, switching on the illumination, moving down the awning or opening the garage door




Rearfield detection.

A typical feature of comfort is the practical rearfield detection. When stepping out of the house it automatically switches on the outdoor lights. That means you do not step from the illuminated hallway directly into the dark, but are greeted by a reassuring light in front of the door.
