Systems

 

 

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. 

Microgrids are the hot new idea that’s been around forever. Thomas Edison’s first New York City power plants could be considered microgrids because those generating stations each acted independently from the others, serving their own “islands” of connected loads.

There has been discussion about unwanted alarms in the last few years. The fire service says this is “an industry problem,” but is it? What can be done to improve the reliability of fire alarm systems so people stop ignoring alarms when they activate?


Contractors often experience some confusion over the types of circuits required and permitted for fire alarm system installations. First, contractors need to recognize that they must install all circuits as required by chapters 12 and 23 of NFPA 72 2016, National Fire Alarm and Signaling Code.


These days, it is becoming more common for low-voltage contractors to specialize in a specific type of work (such as security or audiovisual) or a specific customer base (such as hospitals or schools).
