DPS KDA 864, User Manual

BASE AND SATELLITE UNITS • SOFTWARE DETAILS
Normally Closed Alarms are essentially detected as
changes in the position of a switch. The
KDA assumes that conditions are normal
when a switch is open and triggers an
alarm when it closes. In some applications
this is reversed and the alarm occurs when
the switch opens. Check Normally Closed
if you have any alarms that are wired up
this way.
Normal Dialout Dial Alarms if NORMAL dialup alarm
reporting has been selected under Edit
Docking Ports - Secondary Port, alarms
checked here will be dialed when they
occur (they will also respond to any polls
received on the primary port).
Backup Dialout Enable Dial Backup if BACKUP dialup
alarm reporting has been selected under
Edit Docking Ports - Secondary Ports,
alarms checked here will be dialed when
they occur if communication fails on the
primary port.
When Firmware Qual Time is the time period that an
alarm must be active before the KDA will
consider it to be valid and start to report it.
Range and resolution depends upon
Qualification Units.
Qual Units time units — tenths of sec-
onds, seconds or minutes — referred to
by the Qualification Time entry. Units
apply to groups of eight consecutive
alarms.
Use Alarm 1 If you are physically located near a KDA,
you can acknowledge alarms directly to
the device. Wire up a switch(usually a
push button) as Alarm 1, and check this
entry to tell the KDA to treat it as an ack.
Activate Relay 1 When checked, closes Relay 1 whenever
an alarm on COS occurs and keeps it
closed until it is ack'ed. This is
often used to sound a buzzer, etc.
Type is Timestamp or E2A
for local ack
