Wireless doorbell LTC LXDZ1 with thermometer, AC 230V

LTC Wireless doorbell LXDZ1 ELECTRO is a wired chime unit with an integrated thermometer that operates from AC 230V and pairs with a battery-powered push button. The product combines visitor signalling and local temperature readout, offering up to 120 m range in open conditions and 36 selectable melodies. It is intended for residential and small commercial premises where mains power is available and a radio doorbell solution is required.

Advantages

Wireless communication at 433.93 MHz supports reliable pairing and a line-of-sight range of up to 120 meters, while 36 melody options permit ringtone selection to match user preference. The unit delivers a maximum sound level of 85 dB.
