About ESS Home Toxic Gas In order to reduce the potential for injury to plant personnel and first responders following strong motion seismic events, fire codes typically require... detection sensors or operator emergency power off buttons. These systems normally have 'inputs' available to receive a signal from a seismic switch in order to 'trip' the gas cabinets.... The ESS Saturn Seismic Switch is an effective solution for this application. Using three (3) seismic switches, users can implement a 2/3 voting scheme via their life safety system...

for earthquake actuated shutoff systems for industrial and commercial loss mitigation. Contact Us Links Because it is mounted in the base of the seismic controller or seismic switch..., low level seismic advisory alarm, high level seismic shutdown alarm, SCADA ready (dry, isolated Form C alarm relay contacts), remote trip, remote reset, sensor self-diagnostics... to 2 hours for the entire system (actuators, 24Vdc back-up power, alarm signal verification, etc.) The minimal maintenance requirements for ESS seismic controllers lower the cost...

and commercial loss mitigation. Contact Us In 2009, a M3.0 seismic event centered in Rancho Cucamonga, CA triggered the early warning systems at multiple schools in the Central School... District. The Guardian 2000 Seismic Controllers installed at three schools within the district have been operating since 1995 (following the Northridge EQ1994). Each unit has... a pre-recorded message which is automatically fed into the school's PA system upon detection of a seismic event. Unfortunately (fortunately for the students) the event occurred...

for injury and property damage from natural gas sourced explosions and fires following strong motion seismic events, municipalities and insurance companies are beginning to require... targeted at properties utilizing natural gas in Seismic Zones 3 & 4 (as defined by the Uniform Building Code, published by the International Conference of Building Officials). However... actuated gas shutoff devices: a) pipe-mounted mechanical seismic valves which release stored potential energy (i.e. spring) resulting in valve closure and, b) active seismic systems...

and the pump house might be released into the environment. In the event that product is being pumped at the time of a significant seismic event, the threat of environmental damage... increases. ESS' Apollo 2100 Series Seismic Switch is a key component in the earthquake actuated shutoff system. The standard Apollo unit provided a simple, direct interface... to the client's PLC; enabling the Pump House control logic to automatically shut down pumping operations in response to a strong seismic event. At the time of commissioning, several tests...
