Level 3 Zone 4 Compliant Seismic Dampening Device for Telecommunications Equipment.

SAMPLE APPLICATIONS

 
QBC-12 Kit QBC-36 Kit QB Retrofit  


 

LOOS & Co., Inc. is the exclusive manufacturer supplier of the (Patent Pending) Seismic Dampening Device. This device is designed to provide the added shear resistance and protection required for earthquake protection of expensive electronic or telecommunications equipment, in particular that which may be required for post earthquake recovery communications.

    The was tested at Seismological Laboratories in Quebec, Canada in accordance with NEBS (Network Equipment Building Systems) Specifications for Level 3 Zone 4 Compliance under the rigorous requirements of Telcordia Technologies GR-63-CORE Physical Protection Standard for Earthquake/Vibration protection. Telcordia Technologies (formerly Bellcore) has established Telecommunications Industry Standards for the protection of telecommunications equipment from various hazards. On August 11, 2000 the was Certified Zone 4 Compliant.

    The is manufactured from stainless steel, shielded with a non-conductive vinyl coating and includes a stainless steel stud bolt for connection to equipment. An angle bracket, used for connections to earthquake bracing struts, is also available. The angel bracket is manufactured from mild steel and is shielded with a non-conductive vinyl coating.

    The is available with 3/8", 1/2" or 5/8" National Standard Machine Threads. Please contact LOOS & Co., Inc. at 1-800-321-5667 for pricing and delivery.



NEBS
(Network Equipment Building Standards) sets the conformance requirements that regulate both the quality and reliability of telecom equipment used throughout the telecommunications industry.

Bellcore
(Bell Communications Research) established NEBS compliance as the telecommunications industry compliance standards to insure that communications equipment remains functional at all costs.

Telcordia Technologies
Telcordia was created during the divestiture of the Bell System in 1984 to serve the Bell Companies. Telcordia publishes the NEBS GR-63-CORE Physical Protection Standards, including Level 3 Zone 4 Compliance Testing, and is intended to address issues of reliability of telecommunications equipment designed around a central office (CO) installation.

GR-63-CORE
GR-63-CORE Physical Protection deals with physical characteristics of the equipment. The earthquake simulation of GR-63-CORE is a severe test created by Telcordia. It simulates a 32-s time-history shock pulse with the shock response spectra (SRS) at the base of the frame in the range of 5g and a low-frequency time history that produces of approximately 10 in. peak-to-peak. The unit under test is mounted into a Zone 4 certified test frame that is configured to duplicate the mass and stiffness of a fully loaded frame. The excitation of the framework is measured at both the middle and the top of the frame, when the 32-s time-history shock pulse is performed. The displacement at the top of the frame is measured relative to the base must not exceed 3 in. zero to peak and the unit under test must be functional both before and after the test, with the objective for the unit to function during the test.

Liability
Public Laws 95-124 & 101-614 "Earthquake Hazard Reduction Act", Executive Order 12699, the NEHRP (National Earthquake Hazards Reduction Program) Standards, the ICBO Uniform Building Code, the BOCA National Building Code, the SBCCI Standard Building Code, the IBC International Building Code and FEMA all contain requirements for earthquake protection of communications equipment, in particular that which is used for post earthquake recovery communications. Maintaining functionality of telecom equipment is vital to the income stream of the communications companies. Its functionality is also a liability concern. No one, including LOOS & Co., Inc., can guarantee protection against property damage or loss of life that could be associated with loss of service due to earthquakes. However, failure of the communications company to protect its telecom equipment from earthquake damage and associated service outages, as prescribed by the industry's state-of-the-art NEBS Physical Protection Standards, invites liability risk (not to mention the loss of revenue from the service outages).
