Busch-Watchdog 280 MasterLINE

Technology that reassures

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.

With a corner adapter, two sides of the house can be detected with the Busch-Watchdog 280. 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.

In comparison with the Busch-Watchdog 220 MasterLINE the Busch-Watchdog 280 MasterLINE offers a wider lens and a larger detection angle of 280°.

All loads can be connected to both movement detectors, with a maximum of 3,680 W/VA. Like all Busch-Watchdogs, the models are easy to operate with practical functions such as operating mode, twilight setting, switch-off delay and short-time pulse. And the automatic range stabilisation keeps the coverage constant during different weather conditions. The Busch-Watchdog 280 MasterLINE impresses with automatic interference suppression and presence simulation - ideal during the holiday period. An added advantage is the dismantling protection.
