A partition refers to a sectioned-off division of an alarm system that can be operated independently from the rest of the system. On a partitioned system, only the zones associated with the partition will be affected. For example, if you set up your basement suite (Partition2) as a separate partition from your home (Partition1), you can selectively arm and disarm each partition at will. Alternatively, if both your partitions are armed and you choose to disarm Partition1, your basement will remain armed and protected until you choose to disarm it.
