Wireless chime systems use radio frequencies (RF) to transmit a signal from the push button to activate the chime. To prevent interference with your neighbor’s wireless chime, Heath/Zenith chimes come with 128 different security codes. This code technology makes sure your door chime only works when your push button is activated. Heath/Zenith wireless push button could have a range of 100-150 feet. Wireless chimes allow you to easily add to, or replace your current chime, even if it is wired. Several Heath/Zenith push buttons utilize patented LED lights to illuminate the button giving you the look of a traditional wired push button. All Heath/Zenith wireless chimes and push buttons are compatible. RF does not penetrate solid rock or brick walls.

Wired chime systems are mostly commonly installed when homes are built. These hardwired chimes draw power from your homes electrical wiring, but power is “stepped” down through a transformer to create a safe low voltage system. There are two types of wired chimes: mechanical and electronic. Mechanical hardwired chimes work with tone bars and a solenoid. The solenoid strikes tone bars, creating a familiar Ding-Dong sound. Some electronic wired chimes use a speaker and sound files to create chime sounds. Electronic chimes offer more sounds than just a traditional Ding-Dong.
