84 CHAPTER 7 • CHANNELS-ALERTS-ZONES
Alerts
The alert is the mid-level detection unit and is used to define the corresponding channel’s
output (see Figure 7.18).
Figure 7.18 – Alert Configuration
Enabling an Alert
When an alert is enabled, the alert section of the setup screen turns white; when an alert
is disabled, the alert section turns dark gray. A normal channel contains alerts 1 through 4
and a latched channel contains an ON alert and OFF alert that cannot be disabled.
Each enabled alert must have at least one enabled zone. If you attempt to save an invalid
alert configuration, a prompt will appear asking you to activate one zone for each enabled
alert.
Logic (OR/AND)
An alert’s logic setting specifies the Boolean logic operation to be applied to the alert’s zone
outputs. The available options are OR and AND. If OR logic is selected, the alert will turn
ON if one or more zones have active outputs; if AND logic is selected, the alert will turn ON
only if ALL enabled zones have active outputs.
Inverted Zones
In order to provide more flexibility, an alert can invert a given zone’s output BEFORE apply-
ing the alert’s specified logic operator on the zone outputs.
For example, if an alert has only one enabled zone (zone1), and that zone’s output is OFF
(did not find a qualified detection in the zone), then the alert’s output will be OFF. However,
if the alert were configured to invert the zone’s output, then when the zone’s output is OFF,
the alert’s output will be ON.
Zones
The zone is the lowest-level detection unit. A zone’s output is used to define the correspond-
ing alert’s output.
