Value The current value of the alarm input:
• for a digital input — the state of the digital circuit
associated with the trigger (open or closed).
A value of open indicates that the external
equipment has not shorted this digital input to one of
the four common ground pins. If no external
equipment is connected to a digital input on an
Auxiliary Alarm card faceplate or External Alarm
connector, all digital input ports read open.
A value of closed indicates that the external
equipment has shorted this digital input to one of the
four common ground pins.
• for an analog input — the current voltage level of an
analog trigger, in volts. If no external equipment is
connected to the Auxiliary Alarm card faceplate or
External Alarm connector, both analog inputs show
no applied voltage (0.0V).
Description A description of the alarm input
# A summary of the alarms that are using this input as a
trigger. Each input can be used for up to four alarms.
Threshold The threshold value:
• for a digital input — all digital inputs are considered
normally open; therefore, the threshold for each
alarm is monitoring the input closing
• for an analog input — the voltage threshold for the
alarm
• for Ethernet ports — the operational state threshold
Severity The severity level for the specified alarm input: critical,
major, minor, or warning
Alarm Id The alarm identifier (1 to 2147483647)
Threshold State The threshold state indicates whether the input state
contributes to the alarm:
detected: this input triggers the alarm into an
alarm-detected state
ok: this input does not trigger the alarm into an
alarm-detected state
