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.

Step One: Commissioning

In its basic form, commissioning means testing every device, process and procedure in an integrated systems solution to ensure the final specification operates as planned and according to the owner’s design. 

A Key Component of Reliability

I have often described the reliability of a fire alarm system installation as dependent on four elements: design, equipment, installation and maintenance. I have also explained that the last two elements contribute the most to a fire alarm system’s operational reliability.
