________________________________________________

Note: For the purpose of example, Alarm 2 has been set differently than Alarm 1.)

Note: An alarm in 'alarm condition' is signaling that action must be taken such as correcting the alarm or the analysis concentration. If an active (not defeated) alarm has been set to HIGH at 20.0 ppb, and the analysis concentration is above that level, then the 'alarm condition' is occurring.

DEFEATED: If an alarm is defeated, its relay is de-energized, regardless of failsafe condition. A defeated alarm does not react to a transition over its trip point in either direction.

HIGH: If an alarm is set as HIGH, it will not create a new alarm condition (see latching) if the analysis concentration is below the trip point, if the analysis concentration is above the trip point, then an alarm condition will be created or maintained.

FAILSAFE: A non-defeated alarm that is in FAILSAFE mode energizes an alarm relay in a non-alarm condition and de-energizesan alarm relay in an alarm condition.

Note: Failsafe condition of an alarm is in software. This is not related to relays that have both normally-open and normally-closed terminals.
