Low Voltage Wiring

What is low voltage wiring?

Low voltage wiring systems have been around for over 50 years. First made popular in the 50’s and designed into modern American homes and promoted by architectural luminaries such as Joseph Eichler and Terry Waters


Low voltage systems allowed for greater flexibility in lighting and ease and convenience for homeowners as far as controlling the systems they chose to install. In those days low voltage was reserved mainly to lighting and security. Thermostats, telephones and doorbells/intercoms are examples of low voltage uses.

Today more newly built and remodeled homes install low voltage systems to run the devices that make life easier and homeowners safer while home or away.Low voltage wiring is the wiring used for telephone, intercom, alarm systems, audio, video, data, HVAC or even the weather station and is generally for electronic devices using less than 24 volts.

Lighting Control

Today high-end lighting control systems have done away with high-voltage wiring run within the walls to the light switches, instead small gauge, low-voltage cable is run to switch locations. Now when wire is run to a switch location it may consist of separate wires so that multiple light loads and lighting choices can be controlled from that one location. Low voltage lights offer more choices to set lighting moods and can save considerable amounts of energy. Low voltage lights use less than half the energy of comparable 120 volt lights.


Security systems have been around for a long time  but today’s security systems are capable of multiple tasks. One popular group of devices are the  tri-tech detectors that detect motion in your yard and the interiors of your home. Where the detectors of yesterday detected only motion today’s detectors look for movement and heat variations using microwave and infrared sensors. Have a pet? You can adjust your detector so Fido doesn’t trip the alarm when he goes out to the yard.

Whole house entertainment is controlled by cables run to controls mounted in any location you choose and to the devices you control, such as your TV, stereo or radio.
