Send report
: see Alarm Report Options, below.
Fast logging
: alarms have the ability to influence the hydroSpider’s logging period when they
activate. See 5.10.8 - Advanced - Fast logging.
Stop fast logging when
: determines when the alarm should stop influencing the
hydroSpider’s logging rate. It can happen either when the alarm condition goes inactive, or
when the alarm is acknowledged (see 5.10.5 - Alarm Acknowledgement).
Message
: this text will be present in alerts sent by this alarm.
Auto acknowledge time
: the amount of time after being triggered which the alarm should
be automatically acknowledged (see 5.10.5 - Alarm Acknowledgement).
5.10.2
Alarm Actions
Each alarm can initiate a number of actions:
Control action
: see 5.10.7 - Alarm control activation and deactivation.
Alarms can optionally affect the selected control:
o
Continuously
: simply turns the control
on
or
off
. The control will remain in that
state until it’s changed manually, or by another alarm.
o
Pulse
: turns the control
on
or
off
for a period of 1 to 999 seconds when the alarm
goes active.
Counter action
: Alarms can increment a virtual counter, or reset any counter, making it
possible to count external events, such as the number times an input threshold is exceeded.
This facility is especially useful when combined with
Super Alarms
. For example, an alarm
could activate a water sampler and increment a counter whenever a defined event occurs,
until a maximum sample count is reached.
The following actions can be performed on the specified counter or event channel whenever
the alarm is triggered:
o
Increment
: increment a virtual counter by one (only available for channels with
Source =
Virtual
).
o
Reset
: reset a Counter or Event channel to zero.
Log action:
This option makes it possible to log another channel whenever the alarm is
triggered. This is useful if, whenever one input triggers an alarm, you want a snapshot of
another input's reading at that point in time.
Channel to log
: The additional input channel to log whenever this alarm is triggered.
Perform actions
: This option specifies under what conditions the above actions will be
performed:
o
Once until alarm reactivated
: The actions will be performed whenever the alarm is
activated, regardless of whether it has been acknowledged.
Note that the alarm must go inactive and then active before the alarm actions will
occur again.
