In a fire alarm system, which function provides output to the system’s devices?

• A. Initiation function
• B. Notification function
• C. Control function
• D. Detection function

Answer: (C)

The function that provides output to the system’s devices is the control function. In a fire alarm system, the control function acts as the brain: it receives signals from detectors and initiations, processes the information, and then energizes or commands the system’s outputs such as alarms, strobes, and other actuators. This coordination is what actually causes the audible and visual alerts, door releases, or other actions to occur.

Understanding the others helps: detection is about sensing the hazard (smoke, heat, etc.), initiation is about starting the alarm (manual pull stations or automatic triggers) and serves as an input to the system, and notification refers to the actual alerts produced for occupants. But the output to those devices is driven by the control function, which ties inputs to the appropriate outputs.
