What do Low Voltage Technicians do?

High voltage may be popular in rock-and-roll, but in your line of work, it’s low voltage that keeps you going. As a Low Voltage Technician, you’re in charge of choosing, installing, and maintaining low-voltage systems and cables. TV or security alarm wiring and cables are common examples of installations that you work with.

What exactly is low-voltage wiring? It covers everything from communications and entertainment systems, like TVs and telephones, to small electronic devices, like doorbells and thermostats. You set these controls as a Low Voltage Technician up on the client’s end, and ensure that the wiring is properly installed to avoid malfunctions. On the job as a Low Voltage Technician, you visit with clients who need an installation or repair performed. You scope out the job, and determine what tools you’ll need and how long the project will take. A malfunctioning thermostat may be the result of a single frayed wire, or it may be due to a poor wiring job that needs to be redone.

After diagnosing the problem, you correct it. If a new installation is needed, you help the owners choose a system that fits their needs and stays under budget. Once all the parts are in stock, you go to work rigging it all up.

Think of yourself as a Doctor of electronics making house calls to check on faulty wiring. Whether it’s a doorbell that’s stopped working or a cable connection that flakes out in the middle of the big game, you diagnose the problem and find the solution.
