There are six families of alarm masks:
• ARK1r_AlarmJavaEnable: the selected alarms status is notified on the Java
alarm page icon.
• ARK1r_AlarmFrontPanelEnable: the selected alarms status is notified on
LCD display lighting the alarm button and listing the alarms in the Alarms menu
(refer to Alarms Menu paragraph).
• ARK1r_AlarmEventsEnable: the selected alarms status generate an alarm
event that will be logged in the event memory (refer to Events paragraph).
• ARK1r_AlarmRelay: the selected alarms switch-on the corresponding relay.
• ARK1r_AlarmTrap: the selected alarms generate the corresponding trap
message.
• ARK1r_AlarmRfEnable: the selected alarms switch off the RF output. The RF
mask is almost entirely fixed in order to avoid board damages or
malfunctioning.
Each alarm mask is a 32 bits word and each alarm represents one bit (0: Off, 1: On). Set the
decimal value corresponding to the mask you want to activate in the relative leaf. The
following table shows the bit-to-alarm association.

E.g. if you want to enable the No MIP and No Input alarms of a generic alarm mask, set the
decimal value of 805,306,368 that corresponds to a binary value of
0011 0000 0000 0000 0000 0000 0000 0000.
