Main Menu / Alarms / Alarm Latch
Figure 42. The alarm latch menu
This feature determines how the unit latches alarm conditions.
Select from the following options:
Latched: The alarm is activated until it is silenced and acknowledged by the user.
Transparent: The alarm is active only while receiving alarm input. The alarm condition is canceled when the
alarm input ceases.
Timed Out: The alarm condition is latched for the amount of time selected in this menu, then it is
automatically silenced and acknowledged. If the alarm input exceeds the duration specified in this menu, the
unit silences and acknowledges the alarm when the alarm input ceases. Select the timeout duration, the range
is from 1 to 250 seconds.
Transparent alarms cannot be silenced and acknowledged. If transparent mode is preferred, but the ability to
silence and acknowledge alarms is desired, select Timed Out and set the Alarm Timeout to two seconds.
