The common area of a partitioned system is a part of the premises shared by users of all the system's partitions. One example of a common area would be the lobby in an office building.

• Common areas are configured at the system control panel by your security professional. Settings for a common area in Remote Services must match the configuration that was established in the panel. Making these settings in Remote Services will not pass the configuration to the panel.
• Common areas can be protected by sensors and other devices, but are governed by unique criteria for arming and disarming.
• Typically, security in a common area cannot be armed until all other partitions in the system are armed.
• By the same logic, common areas are typically disarmed automatically when one partition is disarmed.
