Doorbell?
We have an ancient Freidland door chime which Dongs but no longer
Dings:-) Ive been looking for a replacement but cant work out if I need an AC or DC bell unit to continue using the current 12v Freidland 764 transformer. So far Google hasn't been very helpful, do any of you know if this thing is DC or AC? Mike |

You don't need a new bell just a clean out and a new spring. The bell works
simply like a solenoid. The spring brings the plunger back and it overshoots and hits the dong then goes back to the middle again. I had one for years. As for AC bell transformers, and new bells the answer is it depends. Its pretty trivial to add a bridge rectifier and convert to DC inside a box somewhere but you need to know the working voltage and current of the new ball and if its wrong it might just be cheaper to get a psu for the new one. I on the other hand used to enjoy repurposing stuff and indeed repairing bells. There is nothing wrong with those old chimes unless you need a repeater somewhere else in the property. If you are going to do that then get a wireless door intercom. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

Yes the transformers are just that. as I say its simply operating a solenoid
and has switches to stop it or springs to make it go both ways. The reason a ding or a dong is not working is usually switch, spring or dirt related.

Have you tried cleaning it and making sure the spring return still works? That Friedland transformer will be AC. If you want a basic doorbell, that will be OK on AC. -- *Middle age is when work is a lot less fun - and fun a lot more work. Dave Plowman London SW To e-mail, change noise into sound. |

Brian Gaff formulated on Sunday :

The reason a ding or a dong is not working is usually switch, spring or dirt related. There are no switches, apart from the bell push contacts. The solenoid slug is pulled one way to create the ding, as the button is released the slug is pulled by the spring against the 'dong' bar. |

Brian Gaff explained on 14/07/2019 :
You don't need a new bell just a clean out and a new spring. The bell works simply like a solenoid. You don't, unless the plastic has been deformed by heat as a result of the bell push contacts being shorted. The solenoids are not designed to be powered up for long. |

Both springs seem fine, both gongs sound nicely when struck with the screwdriver handle yet still it only Dongs so Ive wired both door pushes to the Dong end so we at least hear something whichever door push is pushed.
