Lumio DB103B Wired Doorbell, Black

Unlike wireless doorbells that rely on batteries or Wi-Fi, the Lumio DB103B delivers a dependable, hardwired 'ding-dong' chime with zero signal interference. Its minimalist black housing blends into any interior, while the classic two-note tone ensures visitors are never missed.

Highlights

• Wired connection for stable, maintenance-free operation
• Classic 'ding-dong' chime with a single, universally recognised melody
• Compact surface-mount design in black plastic, ideal for modern homes
• Compatible with standard wired doorbell buttons and 8V AC transformers
• Simple 2-wire installation, no batteries required

In daily use

Install the DB103B near your entryway and connect it to an existing 8V AC transformer (sold separately). When a visitor presses the button, the chime produces a clear, pleasant 'ding-dong' that carries through the room. The unit is designed for indoor use only and mounts flush against the wall, keeping wiring hidden. Its fixed volume is adequate for most homes, and the absence of complex settings means it works straight out of the box.
