Eltako Radio sensor

Wireless window-door contact with solar cell and battery, 75x25x12 mm, pure white glossy finish. The window-door contact FTKB powers itself with a solar cell from 100 Lux daylight, otherwise it runs for several years on a CR2032 button cell. A signal is sent each time the door or window is opened or closed. Additionally, the current status is sent approximately every 20 minutes. Installation is done by gluing. Dimensions of the window-door contact LxWxH: 75x25x12 mm, dimensions of the magnet LxWxH: 37x10x6 mm. If the power supply from the solar module is insufficient, the electronics will be powered for several years by an internal CR2032 button cell. To change the battery, simply open the housing. This is also necessary to activate the battery supply by removing an insulation strip. To pair it with a learning-capable actuator, the housing must be opened and the internal button pressed. When window-door contacts FTK are paired with switching actuators FSR14, connections of up to 116 FTK are possible. Please refer to the actuator's manual for this. When window-door contacts FTK are paired with switching actuators FSB14, FSB61NP, or FSB71, a lockout protection is established when the door is open, which prevents a central off command. Please refer to the actuator's manual for this. When window-door contacts FTK are paired with switching actuators FHK14, FHK61, FZK14, or FZK61, heating and air conditioning units are turned off when the window is open. Both the window-door contact and the magnet have a marking notch approximately 10 mm long at the point where they must be positioned next to each other when the window is closed. Their distance must not exceed 5 mm. The wireless sensor can be integrated into various actuators and into the building wireless visualization and control software.
