360° surface-mounted motion detector, normally open contact with zero-crossing circuit. 360° motion detector with increased detection sensitivity in the central presence detection area with integrated twilight switch for surface-mounted installation. For use indoors, for example: corridors, entrance halls, etc. The detector reacts to the infrared radiation (body heat) of moving bodies within a detection diameter of 6 m at a recommended installation height of 2.5 m. The signal is sent using a built-in pyroelectric sensor. The brightness value and the duty cycle are set using a potentiometer under an opening on the housing. Ready for use immediately thanks to the factory default setting. Test mode to check the function and detection range.
