5.6.5.10.3 Alarm Delay
An Alarm Delay can be set for each alarm. This delay prevents the alarms from activating until the set
time has elapsed from an alarm active condition. If the alarm condition goes away before the delay is
up, the alarm will not respond. The delay retriggers. If the alarm condition goes away before the delay
is up and then return, the delay is reset and the full delay period will expire before the alarm becomes
active. This feature can be used to overcome spurious or transient alarm conditions.
