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. 

In preparing to write my next article, I often review the topics I have covered in the past year or so, and I consider the issue’s theme.

As most of you know, the codes and standards for fire alarm and mass notification systems change on a three-year cycle. New technology and more refined occupant needs top the list of reasons for most changes.

The predictions have arrived! Analysts expect the first quarter of 2015 to show a rapid rise in commercial construction. Obviously, this is good news on almost all fronts.

One of my responsibilities over the years has been to field questions from our members and authorities having jurisdiction (AHJs) to help them find and understand code requirements. I have benefitted from the process as well.
