Wired Door Chime Nutone LA39WH
The Nutone LA39WH white wired door chime uses a 16 volt transformer. This wired door chime has a unique chord tone for the front door, and a single-note for the second door. This door chime can be painted or wall-papered so it virtually disappears. This wired door chime can easily replace an existing two-note chime without rewiring.
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
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.
