FTKB-wg Eltako Door/window contact Max range (open field) 30 m
Wireless window door contact with solar cell and battery (service life 8 years) 75x25x12mm, glossy pure white. Fixing through adhesive. Smart home sensor Wireless window door contact with solar cell and 75x25x12mm battery. The window door contact FTKB provides itself with a solar cell from 100 lux daylight, otherwise several years with a button cell. When closing and opening, the relevant message frame is sent twice in quick succession. The current status message frame is sent cyclically approx. every 8 minutes. Fixing through adhesive. Dimensions of window door contact LxBxH: 75x25x12mm. Magnetic dimensions LxWxH: 37x10x6mm. If the power supply of the solar module is not sufficient, the electronics are powered for several years by an internal coin cell CR2032. To change the battery, you simply have to open the casing. This is also necessary to activate the battery supply by pulling out an insulating strip. The sensor learn message is sent upon pressing the learning button. When the learn key is released, the voltage message is sent with the same ID. The current voltage telegram is sent cyclically approx. every 60 minutes. To learn in an actuator, the housing must be opened and the internal button pressed. If window door contacts FTKB are taught in in switching actuators FSR14, linking up to 116 FTK is possible. Please refer to the operating instructions of the actuator. If window door contacts FTKB are programmed in switching actuators FSB14, FSB61NP or FSB71, a lock protection is set up when the door is open which blocks a central OFF command. Please refer to the operating instructions of the actuator. If window door contacts FTKB are programmed in switching actuators FK14, FHK61, FZK14 or FZK61, heaters and air conditioning units are switched off when the window is open. Both the window door contact and the magnet have a slot of approx. 10 mm long as the marking at the point where they must be placed next to each other with the window closed. Their distance must not be greater than 5mm. The radio sensor can be programmed in the following actuators and in the building radio visualization and control software: F4HK14, F2L14, FGM, FHK14, FHK61, FMZ14, FMZ61, FSB14, FSB61, FSB71, FSG14, FSR14, FSR61, FSR71, FTN14, FTN61, FUD14, FUD71, FUTH65D, FZK14, FZK61.This text is machine translated.
