Gone are the days when installing a door chime required learning rewiring techniques, finding tools, and putting in hours of labor.  We have entered the age of the wireless door chime. A wireless door chime is simple, easy to use, easy to self-install, and most of all, is affordable. 

How The Door Chimes Work

A wireless door chime works by using a radio frequency to communicate between the push button and the receiver that sounds the chime.  Inside the push button is a very small radio transmitter that activates when the button is pushed.  The transmitter sends out a signal to the receiver.  Once the signal is received, the chime sounds.  The signal for the wireless door chime is coded to prevent interaction with similar systems located nearby, as well as to prevent false activation.  The code can also be changed to include a second push button in a different location.

A wireless door chime may also have a flashing light signal to draw the eye if the chime cannot be heard.  There are two options commonly used by manufacturers to create the light signal.  The first option is a Xenon strobe light, which produces lightening-like flashes of bright white light.  This signal is very good at getting attention and the light reflects off of the walls, making it even more noticeable.  The second option is a flashing LED (light emitting diode), which is less expensive but is also less effective.  The light is not as strong or bright, so it is only noticed if the individual is looking in that general direction.

Important Features To Look For

Features are very important when choosing a wireless door chime.  Many versions offer the ability to choose the chime that sounds when someone pushes the button.  The wireless door chime may have up to eight options to choose from, including bells, sirens, and barking dogs.  The volume options are also important.  Many of the more expensive versions offer a volume control knob or push buttons to control the volume of the chimes.

The range of the wireless door chime is very important.  When choosing a door chime, it is important to remember that the manufacturers quoted maximum distance is based on ideal conditions.  In real life, the range may be much shorter.  Items that interfere with the reception of the signal include metal furnishings, electrical equipment, and concrete walls.  Carefully choose a wireless door chime based on the features you’d like to have to get a product that you will be happy with for many years to come.
