Earthquake Detectors / DSD-80

FEATURES
• Wide operating voltage range (85-305VAC)
• Conformal to international earhquake standards
• Triple axis motion detection
• Automatic self-test
• Internal audible warning
• Internal 24V battery
• 5 programmable relay outputs (5Amp)
• Visual indicators for battery status
• Wide operating temperature range (-10...70°C)

DATAKOM DSD-080 Seismic Security Panel monitors seismic motions of a strong earthquake and provides relay output signals from
it. Output signals are used to shut-off critical installations as natural gas and LPG systems, generators, elevators and the like.
The unit helps reducing damages of a probable earthquake. On its graphical display screen, the unit shows system status.
DSD-080 incorporates highly sensitive triple axis seismic sensors.

The unit is maintenance free and capable of making self-test. The earthquake sensing specifications of DSD-080
conforms to both ANSI Z21.80 (1981), ASCE 25-97 and TS-12884(2002) standards.

DSD-080 operates on mains with a battery backup. 24V/1.2A-h batteries are incorporated to the unit. The unit provides automatic
battery charging feature. During long mains failures, if batteries get low, the unit gives audible and visible alarm.
