Mass notification systems are used to warn of which of the following?

• A. Bomb threats
• B. Fires
• C. Active threats
• D. All of the above

Answer: (D)

Mass notification systems are built to rapidly alert occupants across multiple channels for any type of emergency. They’re not limited to a single threat; they’re used for fires, bomb threats, and active threats because each situation benefits from fast, clear instructions delivered to as many people as possible through phones, PA, text, email, digital signs, and more. This broad capability lets responders tell people exactly what to do—evacuate, shelter-in-place, or lockdown—based on the situation, and to update them as the scenario unfolds. So, the best answer is that these systems warn of all of the above.
