door bell

I want to connect a door bell. There is no existing chime box, just 4 wires. 2 red, 2 yellow. I only have a front door bell. The new chime box has only 3 connections. Which wires go to what connection?

I'm not an electrician, but this wiring sounds like that it is for two doorbells (front and back). You should only need two wires. To my knowledge, there is no universal color code, no grounding requirements, and no distinction between hot and neutral wires for door bells. Chimes operate off of a transformer that converts standard 120v to 20-24v low voltage. Run one bell wire from the pushbutton doorbell to transformer and one from pushbutton to terminal marked FT (Front) on chimes. Run wire from other transformer terminal to chimes (TR to TR.). Connect transformer to power. That should do it. If you have any questions, come back and ask one of the pro electricians in here. Good Luck!

 

hello st3v3ss,
from the info contained in your post it sounds like u have 1 set of wires from the transformer and 1 from the doorbell push button. here is what u need to do.
have a helper hold in on the push button and take a ohm meter or conunity light and connect it between the 4 wires till u get a reading this will be the push button. now connect 1 of the wires from transformer to the common screw of the chime unit and the other to 1 going to push button connect the other wire from pushbutton to the terminal labeled front. make sure power is on 2 transformer, and your door bell shuld work fine.
