Gira Sensotec System 55, without remote control, pure white glossy. Detection utilises the Doppler effect, similar to speed measurement in road traffic. Detection can also take place through non-shielding materials. Toilet facilities, for example, could be covered with a single Sensotec. Non-contact switching prevents contamination. This prevents contamination by viruses and bacteria from the user. Detection at close and long range depends on the reflective surface, speed and type of object (person, animal, object, etc.). Metal frames influence the detection range. Extension of the detection area using extensions. Extension unit operation with rocker switch. Requires an IR remote control for commissioning and setting various functions. Individual brightness value and follow-up time possible (teach function). Sensitivity of remote detection is adjustable. Installation in deep device tray. Fulfils the requirements of the VDI VDE 6008 Sheet 3 directive. The Sensotec is an active motion detector. It detects movements in the detection area regardless of temperature and switches the room lighting on dimmed depending on the ambient brightness. Movement at close range switches the room lighting on undimmed. The switch-on brightness of the room lighting can be set for remote detection. Notes: A remote control is required for commissioning and setting various functions.
