Is there a method to remotely acknowledge an alarm? i.e button on the stick? In reading the manual it didn't appear this was a capability. It appears that the inputs can be used to trigger an alarm, but not acknowledge one.

I read in an earlier post that inputs aren't shared across multiple units. If there is an audible alarm, is that shared between units since there is only one unit connected to the audio panel? Or are the alarms generated on the units not attached to the audio panel silent?
