Which component provides the link to monitoring services or responders?

• A. Interface to monitoring
• B. Initiating devices
• C. Power supply
• D. Smoke detector

Answer: (A)

The link to monitoring services or responders is provided by the interface to monitoring. This component serves as the communication bridge between the fire alarm system and a central monitoring facility or direct responders, handling how alarm signals and status information are transmitted over the chosen path—landline, cellular, or IP—and often including features to supervise and verify transmission. Initiating devices like smoke detectors or pull stations are what trigger the alarm inside the system, but they don’t connect to external responders by themselves. The power supply merely powers the system, and smoke detectors are initiating devices, not communication links.
