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. 

I am always amused when I hear, “No one uses heat-cured epoxy connectors anymore.” In fact, about 95 percent of all connectors, including every factory-made patchcord, uses heat-cured epoxy for its ease of use, low cost and high reliability.

NFPA 70B, Recommended Practice for Electrical Equipment Maintenance, has championed the importance of an electrical preventative maintenance (EPM) program for years.

Residential home fire alarm protection methods can be broken down into two distinct applications: stand-alone detection devices, known as smoke alarms or carbon monoxide (CO) alarms, and combination fire alarm and detection systems that employ smoke detectors and CO detectors connected to a resident

When we install fire protection
in a building, we are focused on active protection systems such as fire alarms, fire sprinklers, clean agents or smoke control.

Optical local area networks (OLAN) will cause you to rethink practically everything you have learned about LANs and LAN cabling. Of course, any major change in technology like this causes FUD (fear, uncertainty and doubt), just like voice-over Internet protocol (VoIP) and Wi-Fi have already.
