Static / Lightning Protection
The DV8000 has been carefully designed and tested to provide reliable protection against static and lightning
induced transients. The special “Zap-Trac” circuit board design catches high voltage transients right at the wiring
terminals, and protection devices are placed in all critical areas to further reduce damaging voltages.
“Watchdog” Monitor Circuit
Even when all precautions are taken to prevent voltage surges from damaging the control panel, it is still possible
to cause temporary disruption to the operation of the microprocessor, causing it to lose track of the program
sequence. The DV8000 is equipped with an external “Watchdog Timer” circuit, which continually checks on the
microprocessor’s program execution.
AC Failure and Low Battery Disconnect
When AC power is lost for an extended period of time, the battery will become fully discharged. The DV8000 will
disconnect the battery when its voltage falls below 9.2V to prevent irreversible damage to the battery. When AC
power is restored, the panel will automatically reconnect the battery to the charging circuit.
RS-232 / 10mA Loop DVACS Option
Either an RS-232 connection or 10mA loop may be used as the interface between the DV8000 and the F1/F2
subset. The interface option is selected by setting the jumpers “LK1”, “LK2”, “LK3”, “LK4” and “LK5” on the
DV8000 Control Panel.
To use the RS-232 option, all jumpers must be set to the “V” position.
To use the 10mA loop option, all jumpers must be set to the “C” position.
Refer to the Hook-Up Diagram in this manual for the location of the jumpers on the DV8000 Control Panel.
It is important that all jumpers be set in the same position. If the jumpers are improperly configured,
damage to the F1/F2 subset or the DV8000 may occur.
