What type of signal is generated by a fire alarm system?

• A. Alarm
• B. Supervisory Signal
• C. Trouble Signal
• D. Intermittent Signal

Answer: (A)

The main idea is that a fire alarm system’s job is to alert occupants quickly. The signal that accomplishes this is the alarm signal, which drives the notification devices like sirens and strobes and can alert responders as well. Supervisory signals are about verifying that protected equipment (like valves or dampers) is in the correct state, not about evacuating people. Trouble signals indicate faults or failures in the system, which alert maintenance but don’t constitute the immediate evacuation alert. Intermittent signals aren’t a standard fire alarm category for a live alarm event. So, the signal generated when a fire alarm is active is the alarm signal, the one that prompts occupants to evacuate.
