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. 

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).

Greenlee offers a variety of fishing reach poles and telescoping fish poles.

The routing of wiring for voice/data/video, security, alarm and control systems is done differently from electrical cable and, in most cases, is completed with different tools.
