Which device monitors circuits for signals and faults, monitors their power supply, and controls fire safety functions?

• A. Fire Alarm Control Panel (FACP)
• B. Main Distribution Panel
• C. Building Management System
• D. Security Control Panel

Answer: (A)

A Fire Alarm Control Panel is the brain of a fire alarm system. It continuously supervises every circuit that connects initiating devices—such as smoke and heat detectors and manual pull stations—and watches for faults like open or shorted wiring. It also monitors the power supply, including the incoming mains and the standby battery, and flags any power issues. When a device detects smoke or heat, or a fault occurs, the panel activates the appropriate outputs—alarm sounders, strobes, and notification devices—and coordinates with other safety functions. It can also trigger building-wide actions required during a fire, such as elevator recall, door release, or HVAC control, according to safety codes and the system configuration. The other options don’t fit because they don’t provide this combination of circuit supervision, power monitoring, and direct fire safety control. A Main Distribution Panel simply distributes electrical power to loads and doesn’t manage fire signaling. A Building Management System oversees various building operations but isn’t dedicated to fire alarm signaling and safety actions. A Security Control Panel handles burglar alarms and access control, not fire safety functions.
