Wireless window handle sensor, matt anthracite, 120x35x7mm, with battery (lifespan 7 years). Installation behind a conventional window handle. Smart home sensor. Radio transmission telegrams for the window positions open, tilted and closed. Status telegram every 15 minutes. Very easy to install under a standard window handle: unscrew the handle, put on the sensor, screw on the handle. In individual cases, the use of the FFG7B- causes the square pin of the window handle to be too short and can be extended by using the SV7x7x14 pin extension accessory.
