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.

Fire is a building’s worst enemy, and time is a critical element. Each minute a fire’s progress can be slowed provides more time for occupants to get out of harm’s way and for firefighters to reach and extinguish a blaze.

Last month, we started the Top 10 in the power quality phenomena category with the most common disturbance: the rms variation. In second place are usually transients, those fleeting waveform changes that are far too brief to be seen by the naked eye in lighting.

Top 10 RMS Variations

From David Letterman to the FBI to Billboard magazine, the “Top 10” can be applied to just about any category, including power quality phenomena. Although it is a highly subjective process, there is some merit in being more than just familiar with them.

Forecast Is A Tool, Not A Prophecy

Each year, we receive construction forecasts that we presumably use to determine what to expect for the promise of work during the coming year. Regardless of what these reports say, the question remains: How do you approach your own construction or work forecast?
