The following is from the alh User's Guide:
===============================================================================
Global Mode
The 'âglobal' options specifies that the alarm handler should run in a
global mode. In global mode an Alarm
Channel's unacknowledged severity and it's acknowledge transients state
will be determined by the current
value of the EPICS database record's ACKS and ACKT field settings. In
local mode, the default mode, the
unacknowledged severity and acknowledge transients settings are local to
the alarm handler.
===================================================================================



Maybe, I can use the "-global" flag along with the passive "-S" flag,
hmmm?

The following is again from the alh User's Guide:
==================================================================================
Passive Mode
Specifying this 'âS' option means that the alh will execute in a passive
(monitor) mode. This means that alh
can not send channel access acknowledgment of alarms and can not do
channel access puts to the
acknowledge transients fields and cannot write to the severity process
variable. It is useful for a nonâoperator
alh user.
===================================================================================
