The main feature of the UDB series wireless doorbells is that most models do not need to be connected to the mains and there is no need to wire the button and the bell itself. The UDB series call buttons are protected according to the IP54 standard (protection against water and dust). A wireless call will be an excellent solution for an apartment, house and cottage.

When you press the call button, the built-in transmitter sends a signal of a certain frequency. This signal is received by the main unit of the doorbell, which contains a receiver tuned to a similar frequency, while the speaker turns on, from which a ringtone is heard (32 ringtones are available to choose from).

Each set of UDB series wireless calls is tuned to different frequencies in order to eliminate the mutual influence of two identical sets of wireless calls on each other.

UDB series electronic calls operate from a 220 V mains. They are used to give an audible signal and can be used in residential and office premises. Wired calls are equipped with a ringtone selection function. The electronic call is suitable for apartments, houses and cottages.
