Custom Timers and Intervals

To limit the time the output is active
If you want the zone to activate while the timer is running:
• Click
TIMER_RUNNING
instead of
TIMER_EXPIRED
. The zone will remain active
while the timer is running. When the timer expires, the zone will become inactive.
10. Type a description in the
Description
box, and then type a comment in the
Comments
box.
11. Click

Correlating the zone with an output
Correlate the zone with an output
1. Right-click the zone, then click
Add Correlations
.
2. Add an output, and then click
Close
.
You have successfully created a timer. The equation you specified in step 8.1.2 starts the
timer. The zone you created in step 8.1.3 becomes active when the equation becomes true
(when the timer expires or while it is active, depending on your choice in step 9). The output
you specified in step 8.1.4 activates when the zone becomes active.
If the equation you created in step 8.1.2 involves elements that might trigger other zones that
are correlated with outputs (for example, the activation of an Input Zone that has its own
correlations or activation in a situation where the Common Alarm Status is active) then the
timer will server as an additional annunciation (activating new outputs while the previously
activated ones continue to operate). If the timer’s triggers are exclusive to it then it will server
as either a delay or a limit on all of the annunciation.

Custom Intervals
An interval is a period of time during the day. Intervals have a start time, an end time, and an
optional day of the week. If the day of the week is not specified, then the interval applies every
day.
Follow the instructions below to make an equation that tells a zone to become active when the
current time is not within a certain interval.
Create a custom interval
1. Create a trouble zone, and then tag this zone
Trouble Zone 1
.
2. Select
Custom Intervals
in the job tree.
3. Click
the
Insert
menu, and then click
Add Interval
.
The interval appears in the right pane. Intervals are numbered starting from 10.
4. Double-click in each column and select a value in the pulldown menus. You must give
the interval the following values. Define the end time first, then the start time.
Start Hour
The hour that the interval starts, on the 24 hour clock.
Start Minutes
The minute that the interval starts.
End Hour
The hour that the interval ends, on the 24 hour clock.
End Minutes
The minute that the interval ends.
