9.5 Global Alarm Setup Menu
This menu controls the overall alarm setup, how all the responses are reset, and the system
state to be returned to once all the responses are clear.
There are 5 display mode settings NONE, LAST, STACK, SWITCH and ROTATE. These
modes change dependent on the response modes which are ACK, TRANSP., and
TIMEOUT.
ACK - Acknowledge Alarm Responses
A response mode of ACK indicates that a response is active from the time the alarm is
triggered to the time it is manually cleared by an operator (select the monitor displaying the
response and press the Alarm Acknowledge key
).
TRANSP. - Transparent Alarm Responses
A response mode of TRANSP. indicates that a response is active until it is manually cleared
(as in ACK response mode) or until the alarm contacts return to their resting state. The
‘TRANSP. alarm timeout’ is the minimum time for which a transparent alarm’s response is
displayed if the contacts reset immediately.
TIMEOUT - Timeout Alarm Responses
A response mode of TIMEOUT indicates that the responses are active until they are cleared
(as in ACK response mode) or until they timeout according to the timeout period set in the
same menu. The timeout operates regardless of whether the alarm contacts have returned
to their resting state or not.
So, for each display mode you can have any of the above response modes. The display
modes are as follows:
NONE = alarms disabled
LAST = (Last In First Out) In this display mode each alarm is displayed on all
the alarm
monitors (according to the alarm monitor list, section 0). The next response to arrive
replaces the current response (on all the monitors), although in TRANSP. or TIMEOUT
response mode the respective timeout periods must have passed first. This minimum
timeout is intended to ensure that no responses disappear immediately without being
observed. In ACK response mode, the responses disappear when a new alarm arrives. This
can lead to an alarm not being displayed. The current response is cancelled regardless of
whether the alarm contacts are still active.
