M-E MODERN-ELECTRONICS ME BELL 331 Wireless Doorbell with Sound-Activated Transmitter, 8 Melodies, 100m Range, White/Silver (41094)

Wireless doorbell system with a sound-activated transmitter that converts your existing mechanical doorbell into a wireless chime. The transmitter detects the sound of your current doorbell and sends a signal to the receiver, eliminating the need for complex wiring. With a range of up to 100 meters in open field and 8 selectable melodies, you'll never miss a visitor.

Advantages

The ME BELL 331 offers flexible installation: the receiver can be wall-mounted or placed freestanding, and the transmitter simply sits near your existing doorbell. Three volume levels plus mute function let you customize the alert, while the blue LED flash provides a visual signal for noisy environments or hearing-impaired users. The system is expandable with up to 4 additional transmitters or receivers from the BELL series, making it suitable for larger homes or multiple rooms.

Suitable for

• Homes with an existing wired doorbell that you want to extend wirelessly
