Two door bells with one bell push
Hi All,
newbie here to this forum so please bear with me if some of my descriptions appear basic.
I came across this great forum through a google search on a similar thread which you guys sorted so hopefully you can help.

Anyway after numorous missed calls to the front door i thought it might be a good idea to add another doorbell chime in the front foom as well as the hallway so i bought a couple of cheap doorbells from amazon here in uk

complete with transformer as the doorbell switch has a 8v bulb light which iluminates so battery is out of the question, ( i do want to keep the illuminating option)

Anyway after looking at the earlier post on a similar project on this forum i understand that i have to wire the doorbells in series, i have done this but although they do ring when wired on their own they are pretty soft when wired in series.

The transformer can be wired to be 4v 8v or 12v and with if batteries were being used the doorbells use 3 x 1.5v.

Can anyone give me some advice of the best way to go with this, should i be using a different transformer? oviously i do want to keep an illumination in the bellpush, can anyone supply me a wiring diagram, can i wire another transformer in there to make the doorbells ring normally but keeping the light please, thanks for all advice...

If using only one transformer then wire from 12v output and wire the chimes in parallel. If wired in series they are only getting a part of the supply.

Hi, I did try using the 12v option but the bulb in the bell push blows after a few hours!

That's not really surprising if its an 8V bulb - you need to use the 8V output from the transformer.

You could then try putting the two chimes in series, so they'd each get about 4V (a bit less than the 4.5V they're expecting from batteries, but probably enough).

Kind Regards, John

Really?

Got a link to that post?

I don't know what (s)he is refering to, either - but if the desire is to try to run an 8V bulb and two chimes designed to run on 4.5V from the same power supply, I don't think there is much choice but to try putting the chimes in series.

An alternative would be to use the 4V output of the power supply, with the chimes in parallel, and see if the lamp was bright enough at the voltage to serve the desired purpose.

The whole exercise would, of course, be simpler if the OP had obtained chimes and illuminated push button which were compatible, voltage-wise!

Kind Regards, John
