I am trying to wire my doorbell i have a red and white wire starting from the button then up the wall to the chime doorbell there are 2 reds and 2 whites.

Front trans rear doorbell wiring. Typically doorbell chimes have three terminals labeled rear trans and front that correspond with each connection. The wire from the front door push button goes to terminal 2 marked front ignore the terminal marked trans. Run wire from the other sides of the push buttons. The wire from the rear door push button goes to terminal 1 marked rear on the doorbell.

Connect the input wires on the transformer to the source circuit using the black to black white to white and ground to green method. Depending on which doorbell you are replacing will decide if you need to use the front or rear connector but you will need to use the trans connector. One wire from the transformer goes to the trans terminal and one wire from each button goes to either the front or back terminals. Terminals on the bell unit are marked front back and trans for transformer.

A doorbell transformer is an electrical component that literally transforms power from a higher. Locate the doorbell transformer in the outlet box near the door. One for the front door the other for the back door. How do i wire this.

You should see at least three wire connectors labeled trans transistor front front door and rear rear side door. Loosen the screw terminals and disconnect the wires. The two black wires are attached to the trans transformer terminal on the doorbell unit and to the front or front doorbell terminal. I only need front.

The twisted pair of white wires are from the 1 other terminal of the transformer and 2 from the second terminal of the doorbell button. Many doorbell units make two sounds. Wiring for two doors is the same as for one with the transformer hardwired to the 120 volt source from a house circuit. For instance if you re wiring a doorbell to your front door flip off the switch that controls power there.

Usually the chime unit has screw terminals that are labeled front rear and trans which indicate the front doorbell wire rear doorbell wire if you have one and transformer wire respectively. The box shows front trans and rear. The rear terminal is where the rear doorbell push button if you have one connects to the chime. Wiring diagram for a two chime doorbell.
