Door Chime

Remember those old fashioned door knockers? You know the ones, they are often used in horror movies as a joke or an indication that the characters are about to enter a very old and very scary mansion. Well, as scary and symbolic as those door knockers can be, they are also very, very out dated. After all, who else by the owner of a large mansion has the money to hire servants to stay close enough to the door to hear a door knocker? No, door knockers are outdated indeed and have been replaced with the technology we all know and love as the doorbell or door chime.

If you live in a large house but can’t afford a servant (and really, who can these days?) then chances are your home is equipped with a door chime. The way the door chime works is simple. Visitors to your home approach the door and see a button. Door chime buttons are generally round or square and are located in a place that will be very visible to visitors who are trying to get your attention. When the visitor pushes the round or square door chime button, a chime sounds in your house. Well, how on earth does that work?

There are several ways that door chimes can operate, but one of the most common ways is through a wired transformer. When your visitor pushes your door chime button, he or she actually sets in motion a rather complex yet instantaneous set of events. First, a switch momentarily closes the doorbell circuit. Second, the door chime transformer lowers the voltage that has been running through it allowing the chime (or perhaps a bell or buzz) to emit and alert you that you have a visitor.

Now, there are upsides and downsides to wired doorbells. The upside is that it works at all times so you don’t have to worry about missed visitors due to a dead door chime battery. The downside is that because your door chime constantly uses electricity, it is also constantly costing you money on your utility bill. Though door chimes do not cost much money, the amount of electricity they use does add up. You will probably notice that they use 1 to 2 Watts of standby power constantly.

If you do not wish to pay fractionally higher power bills or constantly use electricity that could come from some polluting source, then there is another door chime option. You can invest in a battery powered door chimes. The source of the chime in a battery powered door chime is the same – you put a button near door know height outside your home and a door chime sounds when someone presses the button. But the way a battery powered door chime works is a little different.

Wireless door chimes use a built in transmitter. When someone presses the door chime, the wireless door chime sends a radio signal to the doorbell radio receiver located inside your home. The receiver detects the signal and then activates your door chime, bell, or buzzer. These door chimes are generally powered via battery rather than standby electricity, and thus do not use up your household electricity like a wired door chime does.

An even easier door chime alternative is a plug in door chime. Using this door chime is as simple as buying the door chime, plugging it into a plug in inside your home, and then affixing the button to your door. Viola, you have an easy to use door chime that will always alert you when visitors have arrived.
