Citect Shelving and Unshelving Alarm tag

Hi Guys,

I just needed information on how the disable and enable alarm tag works on a redundant system. When the alarm tag gets enabled back, does the system do it on the "MAIN" alarm server or does it do it on both? The reason I ask is that we are monitoring a certain alarm category through cicode which is running on both alarm servers and sometimes the alarmcount has a mismatch. One server sees that particular alarm that just got enabled while the other server does not. 

I am curious to how the standby system syncs its alarm database to the main server.

TIA,

Mark
