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. 

“Where will you be 10 years from now if you keep on going the way you are going?” Napoleon Hill, one of the great writers on success, famously asked this question. When you apply it to the fire alarm and signaling business, it should give you pause.


For electrical contractors installing video surveillance and networked Internet protocol (IP) cameras, now is a great time to think outside of the proverbial box and look beyond the typical security applications of viewing and recording images of people, places and things.

Designers, contractors and authorities having jurisdiction often misunderstand the term “survivable.” They presume it means the installer has chosen to use either a Class A wiring scheme or has placed the circuits in metal raceway.


For security and life safety systems, reliable, high-quality power solutions are critical. Intrusion detection, access control, video surveillance, mass notification and fire systems count on superior uptime and 24/7 availability, which means consistent, dependable power.
