An understated, battery powered doorbell and portable chime with up to 50m wireless range. The IP54-rated waterproof push button simply installs against a door frame using the self-tapping screws provided. House numbers and names can be displayed on the removable name card, protected beneath a clear plastic cover. A simple ‘ding dong’ melody alerts users to visitors via a compact, lightweight chime that can be moved as required within a 50m operating range of the push button; ideal for large buildings and people with impaired hearing.Frequency[tab]433.92MHz[br]Range[tab]Up to 50m[br]Volume[tab]65dB[br]IP rating[tab]IP54 (transmitter only)[br]Battery : chime[tab]2x AA (not supplied)[br]Battery : remote[tab]1x CR2032 (supplied)[br]Dimensions : chime[tab]120 x 46 x 24mm[br]Dimensions : remote[tab]94 x 36 x 18mm[br]Weight : chime[tab]60g[br]Weight : remote[tab]38gColour[tab]White
