What components make up an "alarmed area"?

An "alarmed area" is fundamentally characterized by the infrastructure and equipment that work together to detect and respond to unauthorized access or threats. The Premise Control Unit (PCU) plays a critical role as it is the central hub of an alarm system, managing and processing the signals received from various sensors. These sensors could include motion detectors, door/window contacts, and other intrusion detection devices.

By effectively linking the sensors to the PCU, an alarmed area is able to monitor specific zones, trigger alerts, and initiate a response when a potential breach occurs. This integration is what distinguishes an alarmed area from other security measures that may simply provide surveillance or access control without the active monitoring and alerting capabilities that the combination of a PCU and its sensors provides.
