Overview The Admore A-DB12 is a wired mechanical bell door chime housed in a polished chrome dome — the classic round bell-housing style used for decades in schools, workshops, shop counters and reception areas. When the doorbell push button is pressed, an electromechanical striker hits an internal bell to produce a clear, unmistakable ring tone. Construction & Materials Polished chrome-plated metal dome housing on a black backplate, with a central fixing screw on the bell face. Round, low-profile wall-mount form factor that's instantly recognisable as a traditional bell. Sound & Performance Electromechanical strike against a metal bell produces a clean, loud ring with consistent volume for the unit's full operating life — no speaker degradation, no audio drift. Operates from -10°C to 50°C across UAE conditions. Installation Notes Mount on any wall via the central back-plate fixing and connect to an existing doorbell push button on a 220-240V AC supply. Installation should be carried out by a qualified electrician with mains power isolated.
