Battery-Free Self-Powered Wireless Doorbell

A wireless doorbell whose push button needs no battery at all - pressing it generates the power to send the signal, so the button never has to be opened or serviced. The button is waterproof and frost resistant and works through walls at roughly 30 to 60 metres. The chime unit plugs into a wall socket. Sold as one button with one, two or three chimes, or two buttons with one or two chimes, in white, black, white and gold, or black and gold, plus an 86-type flush-plate upgrade. • Push button needs no battery, ever • Roughly 30-60 m range through walls • Waterproof and frost-resistant button • Plug-in chime unit • Pair one or two buttons with up to three chimes Package contents: • Self-powered push buttons and plug-in chime units as listed in the chosen option • 1 x mounting adhesive pad Please note: • The chime unit is fitted with a Chinese flat two-pin plug.
