soft ding with no dong - needs replacing!

[fredphoesh]

Hello guys,
Weve just added a porch to the house, and the front doorbell is now connected by a cable that is about 5 or 6 meters further... and the ding dong is very limp, sometimes a faint ding, sometimes the odd dong... lousy!
I tried buying 4 C-sized batteries but the unit vibrates continuously when I do that.
First off, I have no idea if there is some hidden transformer in my house. I "THINK" the wires shown in this photo are NOT 220v, but there must be a transformer if they are not... methinks.
So to make the ringer loud, I assume I should buy a new one, but dont know how/if I can use these wires to power the new buzzer and if that will help...
As you can tell, I don't know much about it, but would love some advice (not the "call an electrician" type of advice please
Thanks,
Mark.

hi there
all the connections the builder made are now either under concrete or inside a brick wall.
the fuse board is relatively new and definitely has no doorbell specific trip switches... I think its a transformer i need to find?

There are various possibilities for the failure for your doorbell, the spring could have become tired or broken and need replacing, you have high resistance connections in your supply cable / switch transformer supply cable. Your cables are too thin to carry the required current, your transformer is now too far from your bell to supply the required voltage, the volt drop from the bell push is reducing the voltage in the same way.

A standard bell transformer is not adjustable, they tend to be 12V supplies. The capability to supply current is different for different transformers.

If the transformer is not man enough then it will be slightly difficult for you to get a more powerful replacement as they are not standard items.

A bell transformer could look like any of the attached pictures.
Old bell transformers were generally placed either near the bell unit or near the consumer unit. Occasionally they would be in the roof space above the door or in the attic.New bell transformers can be fitted into the consumer unit, you could also have a transformer looking like a laptop power supply, but much less likely.

The builder should not have covered the connections for the door bell as they should always be accessible (unless they were permanently fixed, so it may be worth looking again.
