Horn Configuration
To configure the audible horn using BESTCOMSPlus, open the Horn Configuration screen (Figure 11-3).
This screen is found in the Settings Explorer under the Alarm Configuration category. If using the front
panel, navigate to Settings > Alarm Configuration > Horn Configuration.
An output contact is configured through programmable logic to energize an audible horn when an alarm
or pre-alarm condition exists. The horn settings consist of an enable/disable setting and a Not in Auto
enable/disable setting. If enabled, the contact output is closed when an alarm condition exists. The
contact output is toggled between open and closed when a pre-alarm condition exists. If the Not in Auto
setting is enabled, the horn is disabled when the DGC-2020ES is not operating in Auto mode.
