• A. Protected Premises System
• B. Central Station System
• C. Public Emergency Alarm Reporting System
• D. Remote Receiving System

Answer: (B)

Central station monitoring. This setup uses a staffed central station operated by an alarm company to receive signals from the protected property. The central station staff then retransmit the alert to the fire department’s alarm communications center. That two-step process—signal arrival at a live, 24/7 monitored facility followed by relaying to the fire department—characterizes a central station system. It differs from a protected premises (local) system, which operates without central monitoring; and from a direct public emergency reporting system, where alarms go straight to the fire department without an intervening alarm company or operator. The central station arrangement adds professional verification and a controlled relay process before responders are alerted.
