Conditional alarm tag

Hi all.

I have some tags in the alarm server, that turn alarm on when are under a specified value.
I need to relate this tags to another 'common tag', so that when the 'common tag' value is 1, the alarms can come out, otherwise the alarm dont' come.

How can I do it?
Can I use the column 'expression' in the alarm server?
Somebody can post an example?
