How Electric Doorbells Work:

• Electric Doorbells That Use Chimes - When you think of a doorbell, the first sound that may come to mind is the chime or buzz that sounds when a visitor arrives at the door. To create this sound, electric doorbells employ electrically powered buzzers or chimes that create sound when exposed to electricity. In systems that use a chime, electricity passes through a metal coil wound tightly inside the chime's housing. As the electricity passes through the coil, according to the online science center, the MadSci Network, it creates a magnetic field
• Electric Doorbells That Use Buzzers - Although many individuals may associate the traditional chime with an electric doorbell, some doorbells use buzzers instead of magnetic or electronic chimes. In systems that use buzzers, electricity flows through a piezo-electric disk when a visitor pushes the outside doorbell button
• Electricity - Whether a doorbell uses chimes or an electric buzzer, it must supply electricity to the device in order to create sound. According to the "New England Breeze," a publication that provides energy-saving tips to New Englanders, most modern household doorbells operate on 24-volt alternating current electricity. Since household electrical wires typically carry around 110 volts or more, electricians install step-down transformers that convert the high voltage electricity to suitable levels for doorbell use. On one side of the transformer, two wires supply electricity to the doorbell chime or buzzer unit. Another pair of wires protrude from the other side of the transformer; these wires extend through the home's walls to the outside doorbell switch. Under normal conditions, when no visitor exists, the outside switch remains in an "open" condition, preventing delivery of electricity across the circuit to the chime or buzzer unit
