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. 

Sometimes, a power quality investigation can lead you to see things that you aren’t really looking for and might be a distraction from what the customer wants you to do.

Electrical professionals understand that the purpose of a smoke detection and alarm system is generally to provide life safety for building occupants. They also understand that the goal of the fire alarm system is to provide occupants with as much escape time as possible.

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. 


Fire alarm systems stakeholders increasingly raise questions concerning the acceptability of using Ethernet and other networks for fire alarm and signaling systems applications.
