LTC LXDZ1 Electro wireless doorbell with thermometer, 230 V

The LTC LXDZ1 Electro is a wireless doorbell whose chime runs straight off the 230 V mains, so there are no chime batteries to replace. The push-button transmitter uses one 12 V A23 battery, and no wiring is needed between button and chime. A thermometer built into the chime shows the room temperature.

The maker highlights: it uses radio at 433.93 MHz with a range of up to 120 m in ideal conditions. There are 36 melodies and the volume is 85 dB. It also works as a call button in shops, offices or for someone who needs care.
