The AlarmCountToRelay component allows you to link from an Alarm Class component to monitor alarm count and send an associated
boolean output to a relay whenever there is an increase in the alarm count. The alarm count type that you choose to monitor
is optional and includes the alarm states or statuses, as described under the “Alarm Count Type”, below. This component may
be used in security applications or situations where you want to connect the occurrence of a new alarm with an event such
as a light, horn, or other signal which requires a relay connection. When an alarm count increases, the component’s Relay
Out property is set to True from False
and maintained at that status for the amount of time that is specified by the Timer property value.
AlarmCountToRelay component properties are described below:
-
Alarm Count
When the AlarmCountToRelay component is linked to an alarm class component, this property displays the current alarm count for that alarm class component. The numeric value of this property dynamically displays the number of alarms of the type specified in the Alarm Type Count property.
-
Relay Out
This property provides the boolean output value for linking into a relay control component. The default value is false and the active value is true. When this property transitions to true, it stays in the true state for a time equal to the value of the Timer property.
-
Timer
This property allows you to set a value that specifies how long the Relay Out value is to be held in the active (true) state.
-
Alarm Count Type
This property allows you to choose one of the following alarm types to monitor:
-
Any Count
When you select this option, you can link from any alarm type to the Alarm Count property. In this case, an increase in any type alarm count from this alarm class invokes a status change at the Relay Out property for a time equal to the value of the Timer property.
-
Unacked Alarm Count
When you select this option, you can link from the Unacked Alarm Count property on an Alarm Class component to the Alarm Count property. Any increase in the Unacked Alarm Count invokes a status change at the Relay Out property for a time equal to the value of the Timer property.
-
Open Alarm Count
When you select this option, you can link from the Open Alarm Count property on an Alarm Class component to the Alarm Count property. Any increase in the Open Alarm Count invokes a status change at the Relay Out property for a time equal to the value of the Timer property.
-
In Alarm Count
When you select this option, you can link from the In Alarm Count property on an Alarm Class component to the Alarm Count property. Any increase in the In Alarm Count invokes a status change at the Relay Out property for a time equal to the value of the Timer property.
-
Figure 14 shows an example of an AlarmCountToRelay component that is linked to the Unacked Alarm Count property. In this example, the Unacked Alarm Count is 46. Any increase in the number of Unacked Alarms causes the Relay Out property to change status from false to true for a time equal to the value of the Timer property.
