Abstract
Seismic qualification tests on pneumatically operated directional valve assembly and fire alarm panel were carried out in the shake table facility in Structural Integrity Division. Determination of the fundamental frequency for directional valve was carried out in all the three directions independently through exploratory vibration test as per ANSI B 16.41 Annexure E (Para E- 3) to ascertain extent of flexibility as defined in the standard. The fire alarm panel was seismically qualified by using sinusoidal input motion in all the three directions independently to ascertain its capabilities to withstand the expected dynamic, seismic stresses and to ensure that the valves will not be subjected to performance degradation or malfunction under seismic conditions. This report describes the final seismic qualification documentation for directional valve manufactured by M/s Vijay Fire Protection Systems Ltd, Mumbai and the fire alarm panel manufactured by M/s Notifier Inc., USA.
