Recent columns have focused on what is happening with dark fiber, that which is being “lit” to become the backbone of the world’s communications systems. Dark fiber connects data centers, cell towers, cities, towns, governments and people.
The electrical energy usage in most industrial and commercial facilities follows a reasonably consistent pattern from week to week, so a one-week monitoring program usually is adequate to determine what can be done to save 10–20 percent on electric bills.
In the course of daily business, you often receive a request to update or replace electrical systems in a building. Have you ever proactively asked customers to allow you to review and audit their fire alarm systems?
Are your low-voltage and security customers concerned over “hanging” security cameras on the enterprise network and opening it to potential vulnerabilities? Or are they looking at protecting other parts of their commercial facility that may be housing data and other privileged information?
Because of increased pressure from government regulators to provide efficient energy systems, Boston-area developers must enlist experienced contractors with proven track records of providing sophisticated energy systems that ensure high quality and reliability, according to Matthew Guarracino, busi
In June 2015, NFPA members met to hear arguments on motions to change the technical committee actions on a number of codes and standards, including the 2016 NFPA 72, National Fire Alarm and Signaling Code.
When the final camera, intrusion detection, or integrated solution is installed and the security system is commissioned, what comes next? Do you simply collect your final payment and move on to the next project?
While the electric power industry rapidly changes, utilities and building owners will need to accurately model the engineering and economic operations of the power system to make informed decisions, so they require sophisticated modeling-software tools.
Design/build means different things to different people. Regardless, you should know that it places more responsibility on your shoulders as the electrical professional. It means you need to stay abreast of the codes that affect your installations.
While the home-automation market is still in a bit of a Wild West state, the combined factors of industry consolidation and consumers’ growing interest in interoperability are forcing some order into the chaos of available products.
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.
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.
I’m sure all of you have run into an issue such as this when installing a fire alarm system: One authority having jurisdiction (AHJ) wants one thing, and another AHJ wants exactly the opposite. What do you do? You can’t make both happy.
Last month, we looked at how dark fiber is tested to determine its capability of supporting newer, faster transmission networks. Once dark fiber has been tested and its usability confirmed, communications systems can be connected.
