DESCRIPTION
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.
The unit provides 5 high power relay
outputs. Through the programming menu,
outputs may be assigned to any function
selected from a list.
