Label Description
External Alarm Input Summary
Input Id The alarm input identifier
Name The name of the alarm input
Type The type of input: digital, analog, or oper-state (for
Ethernet ports)
Admin The administrative state of the alarm input
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
Alarm State The current state of the alarm input:
ghost: no trigger equipment presently installed
ok: no triggers are detected
alarm detected: alarm is outstanding
not monitored: alarm or all triggers are administratively
disabled
