Wireless window door contact 75x25x12mm, pure white. The battery-free window door contact FTK supplies itself with a solar cell and stores the energy for the nightly operation. When closing and opening, a signal is sent. The current status is also sent approximately every 20 minutes. Attachment by sticking, also for external mounting. Dimensions of window door contact LxWxH: 75x25x12mm, dimensions of magnet LxWxH: 37x10x6mm. Solar-powered energy storage: For testing and operation, the FTK must first be charged for several hours in daylight or artificial light. After that, the device is ready for teaching according to the operating instructions of the actuator. For this purpose, only the magnet has to be held briefly to the position marked with n after the actuator to be programd has been activated. If window door contacts FTK are taught in in switching actuators FSR14, links of up to 116 FTK are possible. Please observe the operating instructions of the actuator for this purpose. If window door contacts FTK are taught in in switching actuators FSB14, FSB61NP or FSB71, a lock-out protection is set up when the door is open, which blocks a central shut-off command. Please observe the operating instructions of the actuator for this purpose. If window door contacts FTK are taught in in switching actuators FHK14, FHK61, FZK14 or FZK61, heaters and air conditioners are switched off when the window is open. Both the window door contact and the magnet have an approx. 10mm long notch as a mark at the point where they must be next to each other when the window is closed. Your distance must not be greater than 5mm. The radio sensor can be trained in the following actuators and in the building radio visualization and control software: F2L14, F4HK14, FGM, FHK14, FHK61, FMZ14, FMZ61, FSB14, FSB61, FSB71, FSG14, FSR14, FSR61, FSR71, FTN14, FTN61, FUD14, FUD71, FUTH65D, FZK14, FZK61, , .This text is machine translated.
