Simple Seismic
Millions of dollars are spent every year on cutting-edge technology for the security industry. While it is common to keep this technology safe from human harm, forces of nature such as earthquakes are often overlooked as potential threats.
Security installers, many of whom specify and install large racks loaded with sensitive equipment integral to the safety of others, should be aware that even slight seismic activity can be detrimental to the stability of the equipment.
No longer simply for earthquake-prone areas, seismic-certified enclosures are being required in an increasing number of environments, from institutional to military and life safety installations. Security integrators and consultants require seismic solutions that are as accessible and practical as the enclosures used in everyday applications.
Keith Carney, vice president of engineering and quality control for Middle Atlantic Products, Riverdale, N.J., outlines three common questions security integrators and consultants should consider when presented with a seismic project.
-
What exactly are the codes required for an enclosure to be seismic-certified? There are five important codes that enclosures and consoles should be certified to meet including Uniform Building Code (UBC) 1997, the International Building Code (IBC) standard of 2000 and 2003, the California Building Code (CBC) 1998, the American Society of Civil Engineers (ASCE) 2002 and National Fire Protection Agency (NFPA) 2003 ratings.

What is the enclosure or console’s availability? Integrators should confirm that a manufacturer has seismically certified products in stock locally, as oftentimes there may be hidden charges attached with shipping or customizing. “The seismic factor should not present a bottleneck,” Carney says. “Integrators should be aware whether a special order is involved because this can stall a project and add to expenses.“

How does seismic certification impact other elements of the system? Oftentimes, large institutional, and military and life safety applications, use raised floor systems. The best way to mount enclosures on raised floors is in conjunction with a raised floor riser base system. Integrators should question whether these elements are also seismic certified. “Systems are only as safe as the weakest element,” Carney says. “So it’s critical that, in raised floor applications, seismic enclosures are mounted on seismic riser bases.”
