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 my 40-plus years in fire protection, I have learned that electrical contractors (ECs) sell and install the lion’s share of fire alarm systems in medium- to large-size buildings. Most of these contractors also finish the installation, pass the acceptance test and move on to the next project.

There is no question today’s fire alarm systems are more complex than they were 20 years ago. More panels are addressable, which means programmers, installers and inspection and testing personnel need to be better qualified.


Do you know everything you need to about the specialty electrical systems you install? What about the new technology that appears on the horizon? Probably not, since you cannot build a profitable contracting business by being a jack of all trades and master of none.

Maintenance and renovation services don’t get much more complex, challenging or fluid than in data centers. As cloud-based computing pervades, data centers are becoming more plentiful, the data they collect and manage is growing, and security needs are becoming more critical.
