Which components are typically used in occupant notification systems?

• A. Exit signs and emergency lights.
• B. Fire extinguishers and sprinklers.
• C. Phone dialers and security cameras.
• D. Alarms, strobes, and announcements.

Answer: (C)

Occupant notification systems are designed to alert people inside a building and guide them to safety during emergencies using a mix of sound, light, and message delivery. Alarms provide the audible alert to wake and warn occupants, while strobes give visual indication for those who may not hear well or in loud environments. Announcements deliver clear instructions or directions to evacuate or take specific actions. This combination directly serves the purpose of notifying and directing occupants.

Exit signs and emergency lights help you find exits and stay illuminated, but they don’t convey real-time emergency instructions. Fire extinguishers and sprinklers are for suppression, not occupant notification. Phone dialers and security cameras relate to security and communication outside of the standard notification messages.
