________________________________________________
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
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
Note: Failsafe condition of an alarm is in software. This is not related to relays that have both
LATCHING: The latching property configures the alarm such that the user must manually relieve the alarm condition even though the concentration no longer violates the trip point of the alarm. So, if an alarm is
