It depends on the system! You can find our user guides here.

It is possible a technician will need to help you, but first you are welcome to try these... just be sure of which system you have before inputting codes!

The main task of a surge protector is to protect electronic devices from “power surges.” A power surge, or transient voltage, is an increase in voltage significantly above the designated level in a flow of electricity. In typical home/office wiring, the standard voltage is 120 volts; if voltage rises above 120, the surge protector helps protect your electronic device. The most familiar source of power surges is probably lightning, though it's actually one of the least common causes. When lightning strikes near a power line, whether it's underground, in a building or running along poles, the electrical energy can boost electrical pressure by millions of volts. This causes an extremely large power surge that will overpower almost any surge protector. In a lightning storm, you should never rely on your surge protector to save your computer. The best protection is to unplug your computer. A more common cause of power surges is the operation of high-power electrical devices, such as elevators, air conditioners and refrigerators. These high-powered pieces of equipment require a lot of energy to switch on and turn off components like compressors and motors. This switching creates sudden, brief demands for power, which upset the steady voltage flow in the electrical system. While these surges are nowhere near the intensity of a lightning surge, they can be severe enough to damage components, immediately or gradually, and they occur regularly in most building's electrical systems. ​ Other sources of power surges include faulty wiring, problems with the utility company's equipment, and downed power lines.

Phone systems need dual protection Even if you protect your business phone system with an electrical power surge protector, it is also exposed to damaging surges from other sources. Telephone and internet lines can also conduct high voltage, so for full protection you should also guard against surges from your phone and cable lines. Essentially, any lines carrying signals into your phone system can carry a power surge and can cause just as much damage as surges over power lines.

Yes! We have 2 levels, which can be setup with one of our Account Managers.

Yes! Our headquarters are in Oklahoma City, but we have customers across the entire great state!

The office is open Monday through Friday, and this is generally when we schedule our technicians to visit sites as well, although exceptions can be made! Emergency service is available 24/7. We are closed most major US holidays.

Yes! We will happily send one of our experts out to survey the work needing to be done and give you a quote. (NOTE: not usually offered for small-scale cabling).
