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. 

For several recent columns, I have been writing about splicing optical fibers. Last month, I covered managing fibers inside the splice trays and closures. But there is even more to know about splice closures.


The evolution of intelligent building system technology has triggered shifting roles for contractors and integrators, and the choices they make in their own specializations over the coming years can mean the difference between winning contracts and keeping customers or becoming less relevant.

Demand for wiring and cabling is expected to grow in the months and years ahead. Low-voltage applications for light-emitting diode (LED) technology and fiber optic cabling within the power-generation and telecommunications industries will help drive this market.

The 93XC OTDR is part of the Greenlee Communications family of fiber equipment.

With the increasing use of fiber optic cable in structured wiring, many electricians experienced in low-voltage copper work are extending their skills to include fiber. Working with fiber requires training and the right tools and testers to correctly install and maintain fiber optic cable.

Fiber Optic Splices

There are two different ways to join two optical fibers: splices or connectors. Splices are permanent joints, while connectors allow the two fibers to be disconnected at the joint.

Access Denied

Access control is nothing new. Locks on doors and windows are a rudimentary form of shutting people out. While not the most effective means of control, plenty of facilities use it as their only means of security. ID cards are nothing new either.

High-Rise Fire Alarm Systems

Delayed notification is a major factor of fire-related deaths in the United States. In most cases, the building occupants did not hear the audible alarms in the building or failed to understand the voice message instructions proved by the fire alarm voice communication system.

Take the Layered Approach to Wireless
by Staff |

Some predict a totally wireless world, but that will probably never happen. There are so many other good media out there-including fiber optics, unshielded twisted pair, coaxial and other bundled wiring solutions-chances are there will always be room for both hardwired and wireless.
