DATAKOM DSD-050 is a high-tech unit which detects seismic motion. On the occurrence of an earthquake it gives audible and visible alarms and closes a relay contact to shutdown gas and industrial valves. Thus it is possible to minimize the fire risk after an earthquake.
DSD-050 is a very cost effective device for shutdown applications. The unit is based on highly reliable dual axis seismic sensors. It is small, maintenance free and capable of performing self-test.
The unit operates on mains power. It incorporates a lead-acid battery and an automatic battery charger which allow uninterrupted operation even in case of AC power failures.
During long mains failures, if the internal battery gets weak, the unit gives audible and visible alarms.
The seismic properties of the unit are conformal to ANSI Z.21-70(1981), ASCE 25-97 and TS 12884 standards.
