Wireless window/door contact with solar cell and battery (lifetime 8 years) 75x25x12mm. Adhesive foil mounting. Wireless window/door contact with solar cell and battery 75x25x12mm. Starting at 100 Lux daylight the window/door contact FTKB powers itself from a solar cell, otherwise several years with a button cell. On opening and closing, the related telegram is send twice in short succession. The current status telegram is sent cyclically every approx. 8 minutes. Adhesive foil mounting. Window/door contact dimensions lxwxh: 75x25x12 mm; magnet dimensions lxwxh: 37x10x6mm. If the power supply of the solar module is insufficient, the electronics is powered by an internal button cell CR2032 for several years. To change only the housing has to be opened. This is also required to activate the battery supply by pulling out an insulating strip. When the teach-in button is pressed, the sensor teach-in telegram is sent. When the teach-in button is released, the voltage telegram is sent with the same ID. The current status telegram is sent cyclically every approx. 60 minutes. For teaching-in into a teachable actuator, the housing has to be opened and the inner button has to be pressed. After window/door contacts FTKB are taught-in in switching actuators FSR14, it is possible to link up to 116 FTKs. Please refer to the actuator operating instructions. When a wireless window/door contact FTKB is taught-in in switching actuators FSB14, FSB61NP or FSB71, a lock-out protection is set up while the door is open and disables a Central Down command. Please refer to the actuator operating instructions. After the window/door contacts FTKB are taught-in in switching actuators FHK14, FHK61, FZK14 or FZK61, heating and air-conditioning equipment are switched off when windows are opened. Both the window/door contact and the magnet have an approx. 10mm long notch to mark the point where they must be located next to each other when the window is closed. They may not be spaced more than 5mm apart. The wireless sensor can be taught in the actuators listed below and in Professional Smart Home controller: F4HK14, F2L14, FGM, FHK14, FHK61, FMZ14, FMZ61, FSB14, FSB61, FSB71, FSG14, FSR14, FSR61, FSR71, FTN14, FTN61, FUD14, FUD71, FUTH65D, FZK14, FZK61.
