X4-LIFE Funktürklingel X4-LIFE ECO

X4-LIFE ECO wireless doorbell. The environmentally friendly solution - without batteries and without cables. This wireless doorbell consists of a receiver and a transmitter like conventional models. Plug the receiver directly into a free socket. But the highlight is the transmitter: just by pressing the bell button, enough energy is generated to send the radio signal to the receiver. So you do not need batteries for the transmitter. You can choose between 25 different ringtones and melodies and also adjust the volume to suit your needs. In addition, a blue LED flashes as soon as the bell has been triggered. The transmitter can be mounted either with the enclosed adhesive pad or with the enclosed screws. The bell is completely self-learning, so you can connect up to 3 transmitters with one receiver. Conversely, you can connect an unlimited number of receivers to one transmitter. So you are guaranteed not to overhear visitors. Features Environmentally friendly wireless doorbell - complete without batteries and cables 25 different tones and melodies Adjustable volume.
