Input zones or doors, which are shared by multiple alarm partitions, are related according to the following rules:
- An alarm partition will only produce an alarm from an input / door common to other alarm partitions if all the alarm partitions containing that input / door are armed. Inputs or doors which are part of “Alarm Level 1 and 2” can be defined in a different way but have to be part of a group.
- Alarm level 1 and 2 (input groups) are processed together as one large group for the purpose of determining whether an input (zone) is also included in another alarm partition definition.
- Common doors which are defined as “Door to be locked on arming” or “Door disabled on arming” in both alarm partitions will revert to their normal state if one or more of these alarm partitions is disarmed.
