Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more.

The new year is upon us. For electrical contractors that continue to add low-voltage security to their operations, there is a light shining brightly on what can really boost the overall future stability and profitability of a company, and that’s the category of video surveillance.


Regardless of the changes in our federal government this year, there is one thing we know for sure: we have a new NFPA 72 2016, National Fire Alarm and Signaling Code from the National Fire Protection Association. Does that mean we should have started using the new code on Jan. 1?
