Doorbell voltage

Common household doorbells will work just fine on 12v DC. The household converters put out 16v AC which is a sine wave. It is the average voltage that rings the bell/buzzer and that is a lot less than the 16v peak. If you look at the RMS (Root Mean Square) of the 16v AC, you will find that the energy content is not far from what you get with 12v DC.

Door Bell Power

My door bell is made by NuTone and powered by 4 C batteries. The bell stopped doing it's 'ding' after about a 300 mile ride. I opened the white box under the fold-down kitchen counter extension and found that 3 of the 4 batteries had come loose and fell out, probably while in travel. The box design and construction is pretty M-Mouse, so I put some fairly thin foam inside the cover of the box lid before replacing it to put a little pressure on the batteries to hold them in place - so far, so good.

My button on my 93 Excella is located on the trailer grab handle next to the door. A couple of years ago the button wires broke off. The repair would involve removing some inner skin. To me it's not worth it. I disconnected the power at the bell itself under the couch. If I ever fix it I may put in an A-oo-gah horn under the stairs.

Sail on silver girl. Sail on by. Your time has come to shine.
