1. Overview
The VBC7000 series seismic detector can be installed
in industrial or workplace environments to prevent
secondary damage in the event of an earthquake by
preventing the release of harmful gases, performing
emergency shutdown of equipment, activating an alarm,
etc.
Main Features
Depending on the intended use of the detector, fifteen•
models are available for accelerations from 12 to 250 Gal.
Faulty activation is minimized as the unit’s construction•
makes it difficult for it to be activated by non-earthquake
high frequency vibrations from sources like machinery or
dump trucks.
Functional checks can easily be performed after mounting•
or installation.
The operating status can be checked visually in the•
indication window, which changes from green to red
when the detector is activated.
