Wiring for a Buzzer on the Back Door and a Bell on the Front Door

To solve the problem of one single bell rung from both the front and back door, you can install both as bell and a buzzer. The buzzer sounds when the caller pushes the back door button while the bell rings if the front door button is pushed, (Fig. 5).


Follow the diagram shown in Fig. 5 for wiring a buzzer and a bell in this manner. The wiring is basically the same as in Fig. 4 except a buzzer is wired in between the terminal screw on the back door button and the terminal screw on the bell.

The buzzer, bell and transformer can be concealed in any desired location.
