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.
