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. 

Appetite for intelligence


The simplicity and ubiquity of home automation means opportunity for ECs. For one thing, today’s systems come ready to install, and contractors can learn installations in a matter of hours rather than weeks. For many ECs, it has been a welcome transition.


Beginning with the 2010 edition of NFPA 72, National Fire Alarm and Signaling Code, all of the “styles” of circuits were deleted, and four “classes” were added. A new chapter, Circuits and Pathways, was added during the reorganization of this code.

Many designers of the notification portion of a fire alarm or mass notification system (MNS) seem unaware of the specific performance requirements for each type of appliance as required or allowed by NFPA 72 2016, National Fire Alarm and Signaling Code.

Based in San Jose, Calif., Integrated Communication Systems (ICS) has been building its success as a low-voltage integrator for 15 years. The 80-employee firm, founded in 2002 by Aaron Colton, president and CEO, serves low-voltage integration needs in San Francisco and the Bay Area.
