Testing System Alarm Outputs
The system provides the following two physical alarm mechanisms:
System Audible Alarm: Located on the SSC, the speaker is used to provide an audible indicator that a minor,
major, or critical alarm has occurred.
CO Alarms Interface: Located on the SSC, this interface provides a DB-15 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.
