The RNP-22 transmitter enables wireless control of receivers of the EXTA LIFE system. It is intended for the implementation of such functions as remote switching on / off of lighting, regulation of lighting intensity, closing / opening of window blinds and garage doors. The transmitter is dedicated for mounting in flush-mounted boxes (minimum Ø60mm) under existing equipment. This allows the use of electrical installation equipment from any manufacturer and does not limit the design and character of the interior. The transmitter is battery powered so it can be mounted anywhere. It has four inputs thanks to which it is possible to independently control up to four receivers (channels) of the system. Triggering is accomplished by shorting a given input with the transmitter's COM cable. Built-in LED indicates transmission, which is coded which additionally ensures control safety.
