The commercial construction market, in general, remains anemic, with one exception: data centers. Not only are we all buying more data-transmitting smart-phones, tablets, web-connected televisions—and, yes, even PCs—we also are moving data from our own hard drives to remote “cloud” servers.
The captain of Road Prison 36 in “Cool Hand Luke,” played by Strother Martin, said the line that appears as the title of this article. Here, it leads to a discussion on the art and science of designing an effective communications system.
No specific market numbers apply to the cable and wire used to install and integrate security and life safety products, according to Maricha Ellis, business manager, security solutions for Belden Inc., St. Louis.
The November Integrated Building Systems column covered the basic business and planning requirements for systems integration. Now, let’s kick it up a notch and review connectivity infrastructure. (Note: part 1 is here.)
Programmable logic controllers (PLCS) have been with us for some time—the first PLCs with architecture and functionality like the ones in use now were built in the mid-1970s. They provide practical means for applying logic to automate almost any function that can be electrically controlled.
Casinos are in the process of transitioning their analog security and gaming surveillance systems into digital despite the economic downturn. A large percentage of gaming facilities, from Las Vegas to Atlantic City, N.J., will upgrade their systems in the coming year.
The demand for security and active life safety systems is growing because there is an expectation of safety in public places, and the new technology is less expensive than doing the job with “feet on the street.”
Servers have changed the way businesses operate, allowing them to increase the number of applications they can use. Aimed at businesses of all sizes, servers do much of the heavy lifting for computer systems.
Various school shootings and natural disasters have thrust mass notification systems (MNS) into the spotlight. Such tragedies have pointed out the need to further examine systems and how they can be enhanced.
True building integration means finding commonalities between building systems and using the appropriate communication protocols to program them. This provides cooperative sequences of operations that offer increased value to the building owner.
Security is serious business, and most of the men and women who work in physical security treat it as such. However, there are times when loose talk out of shop can cause serious security breaches for a contractor’s commercial and institutional clients.
Beyond the bones and bloodlines of electrical installations—the cable, conduit, relays, panel boards and the more sophisticated building automation controls—are the brains, the programmable logic controllers (PLCs).
