Discuss The phantom doorbell!....... in the UK Electrical Forum area at ElectriciansForums.net

A few years ago I fitted a new doorbell, wireless...
It rang randomly, and eventually I discovered my neighbour across the road had bought a similar one...very annoying that when they had visitors, our bell rang.
A quick flick of the micro switches inside sorted it.

Once upon a time, my doorbell was a bell that was wired to a switch on the outside of the doorframe, powered by a 1289 battery...it worked fine for ever...
Progress, eh?

I once fitted a door bell consitsting of a PP9 battery bell push and a transitorised buzzer, got called out to it 18 years later, not working due to bell push corrosion, and had to scrape the push again after another 8 years. How long would a modern fancy one last?
 
years ago, went to a customer to carry out an annual service on the intruder alarm. nice new uPVC door and frame with a shiny new brass bell push. pressed the bell push ( as you do) and got the worst belt i've ever experienced. keys in my hand went over into next door's garden. investigation found the the door fitters had not noticed that the old bakelite push had 240V going through it. so fitted customer a ELV battery bell. ever since then i've pressed a metal push with a VDE screwdriver.
 
I think it's time to open a huge can of worms…lol. It is possible to pick up electromagnetic radio signal depending on the type of dental fillings someone has and the arrangements of those fillings inside the mouth. The ears can pick up that signal and turn it into sound.;)

That's one way to keep the cold callers away from ringing the bell.
