Figure 4-78 Quorum Entry
It is up to the installer to ensure that the quorum entry is appropriate for the configuration. Valid entries are one to
twelve, but a value greater than the number of sensors being monitored by the group stops the group from
controlling the outputs. The default quorum value is 1.
4.13.8 Configure Signals Submenu
The DVP-120C can drive the buzzer, horn, and strobe with different sound patterns to indicate the severity of the
current conditions. These patterns are selectable by the installer using this group of submenus. Once again, the left
and right keys will scroll through the signal types and the up and down keys will scroll to the signal sources.
4.13.8.1 Alarm Signal Summary
The alarm signals are in response to one or more sensors indicating gas levels at or above the sensors’ configured
alarm level.
