Wireless window-door contact with energy generator, dimensions 48x32x11.5 mm, pure white. Also suitable for monitoring drawers and other movable devices. It generates energy for wireless telegrams even under pressure, thus eliminating the need for batteries, connection wires, and standby loss. Installation can be done by gluing, screwing, or using mounting brackets BW3. Smart Home sensor. A wireless telegram is sent each time the door or window is opened or closed (similar to a Hoppe window handle when the window is closed or fully open). Included in the package are a mounting bracket BW and two adhesive foils. The 27 mm short lever can be extended to 48 mm by attaching the included part. When window-door contacts FTKE are learned into switching actuators FSR14, connections of up to 116 FTKE are possible. Please refer to the actuator's manual for this. When window-door contacts FTKE are learned into switching actuators FSB12/14, FSB61NP, or FSB70, a lockout protection is established when the door is open, which blocks a central off command. Please refer to the actuator's manual for this. When window-door contacts FTKE are learned into switching actuators FHK12/14, FHK61, FZK12/14, FZK61, FZK70, or FHK70, heating and air conditioning units are turned off when the window is open. The wireless module contained in the wireless window-door contact can be encrypted into all encryptable actuators of series 61 and 71 as well as into the FAM14 according to the manual. The wireless encryption plug FVST is required for this. Encryptable actuators carry the key pictogram. The wireless sensor can be learned into the following actuators and the building wireless visualization and control software: F2L14, F4HK14, FGM, FHK14, FHK61, FMZ14, FMZ61, FSR71, FSB14, FSB61, FSB71, FSG14, FSG71, FSR14, FSR61, FSR71, FTN14, FTN61, FUD14, FUD71, FUTH65D, FZK14, FZK61.
