Testing System Alarm Outputs
The system provides the following two physical alarm mechanisms:
System Audible Alarm: Located on the SMC, the speaker is used to provide an audible indicator that a minor,
major, or critical alarm has occurred.
CO Alarms Interface: Located on the SPIO, this interface provides a 10-pin connector that enables three dry-
contact relays (Form C) for the triggering of external audio and/or visual indicators. These indicators can be
used to alert that either a minor, major, or critical alarm has occurred.
used to alert that either a minor, major, or critical alarm has occurred.
The operation of these alarms can be tested by issuing the following command:
test alarm { audible | central-office [ critical | major | minor ] }
