Which of the following is a primary function of a central station in an intrusion detection system?

The primary function of a central station in an intrusion detection system is monitoring alarm signals. Central stations are responsible for receiving alerts and signals from various security devices within a facility, such as sensors, cameras, and alarms. Once these signals are received, the central station operators analyze the information to determine if there is a legitimate security threat or if it is a false alarm.

The process involves constant vigilance, ensuring that any potential breaches are addressed swiftly, which is critical for effective security management. By monitoring alarm signals, the central station can coordinate appropriate responses, such as alerting law enforcement or emergency personnel when necessary.

The other functions, while important in the overall realm of security systems, do not fall under the primary responsibilities of a central station. Activating alarms is typically done in reaction to detected conditions rather than being a function of the central station itself. Installing equipment and designing systems are roles usually associated with security system installers or integrators, who are tasked with setting up the physical hardware and infrastructure rather than monitoring existing systems.
