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).
• for an Ethernet port — a value of down indicates an
alarm event; a value of up indicates no alarm
Threshold State The threshold state:
ghost: no threshold is present
not monitored: the threshold is administratively disabled
ok: the threshold is enabled
detected: the threshold has been crossed
Triggers Req'd The trigger condition that is required to raise an alarm:
any: any configured input trigger is required to raise an
alarm
all: all configured input triggers are required to raise an
alarm
