1-channel occupancy detector with two simultaneously operating relay outputs, which enable distribution to different phases
The switching channel with the two relay outputs closes when the operating voltage of the detector fails, so the lighting remains on as long as the two phases of the luminaires are supplied with power.
The device requires an operating voltage. The third phase can be used for this purpose.
Designed for corridors
Version as master device
Detection area can be extended by using slave devices
Manual switching via push-button possible
Additional functions can be set up using the optional remote control.
There are markings to ensure correct alignment during installation
