The ideal solution if an old bell system fails, an additional bell system is to be installed, e.g. for children or the senior apartment in the house, or at the garden wall. Both the bell button transmitter (IP54) and the radio gong (IP20) themselves are battery operated and can be placed so flexibly that you never miss a visit. The connection between transmitter and receiver is coded so that no radio interference or false alarms from neighbouring systems are possible.
2x 1.5 V micro batteries for the transmitter and 3x 1.5 V mignon batteries for the receiver are required for operation.
This range specification, however, is the so-called "free field range" (range with direct visual contact between transmitter and receiver, without disturbing influences). In practical operation, however, walls, ceilings, etc. are located between the transmitter and receiver, which reduces the range accordingly.
