Seismic Design coordination of mechanical services and other plenum located elements, including lights, air conditioning, cable trays, fire suppression systems etc, with the suspended ceiling is essential.
As manufacturers of cable trays, seismic brackets, and light steel keels, we recognize that integrating purpose-built seismic support systems into buildings and critical facilities can dramatically
Up to 50% faster to install, the seismic bracing cable kit system is designed to suspend equipment and other systems to help minimize damage in a seismic event.
Above these cabinets, are cable trays that provide power and communications cabling to the cabinets. Since the facilities were located in a area of high seismicity, the cable tray system was required to be
Requirement: Each straight run requires a minimum of (2) transverse braces and (1) longitudinal brace.
Seismic restraint devices include vibration isolation systems, cable or strut suspension systems, roof attachment systems, and steel shapes. An electrical danger instruction chart is provided (page 160)
