7.2 Alarm Monitoring
The alarm monitoring is always active regardless of Local or remote mode.
Note:
Alarms are abnormal conditions that will be indicated and logged by the M2500, but they will not stop
the engine.
Alarms can be set to continuous monitoring (regardless if the engine is running or not) or
conditional monitoring (only monitored if the engine is running).
An individual programmable time delay is available for each alarm.
A new incoming alarm will always shift the M2500 display to the Current Alarm display. At the
same time the Alarm LED on the front panel will be fast flashing, the common alarm output
(terminal 46) will activate and the Siren Relay (terminals 68, 69 and 70) will de-energize.
Depending on the configuration it is possible to activate one or more of the digital outputs.
The common alarm output will de-activate for 2s and re-activate when a new alarm appear.
The siren relay (terminals 68, 69 and 70) will de-activate for 2s and re-activate when a new alarm
appear.
After accepting an alarm (by pressing the Reset button or external reset terminal 12) the common
alarm LED will change to steady light, the common alarm output and the optional digital output
will remain active, provided the alarm is still present on the input. The siren relay will energize
again after pressing Siren Reset or Reset button or external reset terminal 12.
When the all alarms disappear from the inputs and alarms have been acknowledged, the common
alarm LED will switch off, the common alarm output and the optional digital outputs will
deactivate.
