Busch-Watchdog 180 flush-mounted standard sensor

Hands free for the important things

The convenient home help. The flush-mounted Busch-Watchdog 180 standard is the ideal movement detector for the stairwell, hall and large rooms without a clear overview. They react as soon as they register body heat. And they leave no one standing in the dark.

The optimum shape

A flush-mounted movement detector must match perfectly with its surroundings while at the same time reliably fulfilling its detecting function. The flush-mounted Busch-Watchdog 180 Standard is optimally designed for this. Not too flat and not too high. Nothing escapes their notice. The flush-mounted Busch-Watchdog 180 Standard is available in the design of the Reflex SI Linear switch range.

Everything under control

The flush-mounted Busch-Watchdog 180 Standard offers a large range of effectiveness, especially during a frontal approach. As soon as someone enters the door the switching process is triggered. It switches off automatically when exiting. The detection angle is 180° and extends laterally up to the wall. In spite of its compact dimensions it has a transmission range of twelve meters frontal and eight meters lateral. Depending on the spatial conditions, the connection of an additional movement detector is recommended, which is connected as extension unit. For example, when an area that does not lie within the detection range is accessed.

Tips for industry solutions

Light, when it is needed. And the reverse. Illumination that thinks along. In offices, hotels or public buildings light must function reliably and safely. But only when it is actually needed. Unnecessary switching of light means additional use of energy. The intelligent Busch-Watchdogs handle this task impressively and especially economically in all areas.

Application as main and auxiliary device


If more than only one movement detector is required, additional movement detectors can be installed using extension units inserts. This is a convenient solution for windy cellars or L-shaped corridors.
