Doorbell World Wind up Mechanical Doorbell - White with standard Chrome push

Description

Doorbell World Imperial Doorbells are mechanically operated, requiring no batteries, wiring or electricity. They simply fit to the inside of your front door and give a maintenance free, reliable service. The doorbell uses a clockwork action, needing only an occasional winding of the dome. The Windup doorbells are manufactured and assembled in the UK.

They offer an alternative to wireless doorbells where UPVC door frames (with metal backing for strength and security) can cause problems with wireless signal strength. The clockwork mechanism is released by a thin rod that passes through the door to a bell push button on the outside. This rod is adjustable for different door thicknesses, but where doors are particularly thick, we can supply longer rods up to 12cm. The bell units measure 78mm, (3") in diameter. When fully wound, the bell will ring for approximately 75 seconds, and since a typical visitor will press the bell push for between 2 and 3 seconds, the mechanism will support up to 30 rings.

 InstallationDownload Instructions 

1. The bell unit is normally attached to the door itself rather than a door frame.
2. A hole of 5mm diameter will need to be drilled through the door for the rod to release the wind up mechanism.
3. The Doorbell is supplied fully wound, please do not wind further, as this may cause the mechanism to jam.
4. The rod is adjustable in length, to cope with typical door thicknesses. If your door is particularly thick or thin, additional special length rods can supplied at no extra cost.
5. Additional replacement mechanisms can be supplied if necessary
