DSD-080 User Manual V-1.0
12
The unit provides two
different alarm levels for “Weak Motion” and “Strong Motion”.
The unit has a closed circuit detector at the solenoid relay output. If the solenoid
connection is broken, then a “no solenoid” alarm will occur.
Additionally a “Low Battery” alarm is provided.
Any of the above alarms may be assigned to any relay output. However the Solenoid
output can be only assigned as “Strong Motion” alarm.
When any alarm occurs, related relay outputs become active and the unit gives an
audible alarm.
By depresing the RESET pushbutton, alarms are reset and relays return to their initial
position.

DESCRIPTION
LOW BATTERY
Occurs when the battery voltage is below
the “Low Battery
Voltage” parameter.
WEAK MOTION
Occurs when the measured acceleration is over the user-
defined threshold for the weak motion.
STRONG MOTION
Occurs when the measured acceleration is over the
threshold for the strong motion. This threshold is defined by
international standards and is not adjustable.
NO SOLENOID
Occurs when there is no connection at solenoid output, or
when the conductor wires are broken.
