2 Use the Time Zone drop-down list to attach a

time zone to an input point. For example, to

shunt [deactivate] an input point during a par-

ticular time zone, select that time zone from the

list. The Time Zone defaults to None.

3 When the input becomes active [alarm or trouble

condition], the Hold Time begins counting down.

If the input goes normal before the hold time

ends, the input will wait to report normal until

the hold time ends. If the input goes normal after

the hold time ends, the normal status is reported

immediately.

For example: with a hold time of seven seconds,

when the input is in alarm, the hold timer starts

counting down. If the point goes normal after

three seconds, the normal waits another four

seconds before reporting. If the point goes

normal after ten seconds, the input reports as

normal immediately.

Hold Time defaults to zero seconds, but can be

set from zero to fifteen seconds.

4 Debounce Cycles set the amount of time [in

seconds] that an input must be in a changed state

before that change is reported. In other words, a

debounce cycle instructs the system to ignore an

alarm for a specific period of time.

For example: an input point with a debounce

time of "4" (the default) must be in an alarm

state for four cycles before it is reported as an

alarm. The same is true when it returns to

normal condition. The input point would not

report as normal until it is in the normal state for

the debounce period.

Debounce time can be set in the range of 0 to

255 seconds.
