Alarms
– The Multilog LX 2 has a comprehensive alarm system
that you can configure to send out Alarm messages when
certain defined conditions are breached.
When an alarm condition is triggered a new call frequency can be specified to
allow the observer to gain more up-to-date data during an event.

Note on Hysteresis
: When an alarm is triggered, if the value is
set to zero then immediately the threshold is re-crossed then
another clear message will be sent. If there is a period when the
alarm threshold is borderline, this can result in numerous
messages for the same event. By specifying a value in the
Hysteresis box, you can provide a window that allows the
threshold to be repeatedly crossed without sending repeated
messages. e.g with an Upper limit of 5 and a hysteresis of 1, the
alarm will trigger at 5, but the clear message will not be sent
until the value drops to below 4.
Enter the alarm
