Which of the following is a key feature of a fire alarm system for large occupancy buildings?

A key feature of a fire alarm system for large occupancy buildings is an integrated voice evacuation system. This system is essential because it provides clear, audible instructions to occupants during an emergency, which can significantly aid in the safe and efficient evacuation of a building. In large spaces, where people may be spread out and the environment can become chaotic, a voice evacuation system is critical for directing individuals to the nearest exits and informing them of the situation.

This capability helps minimize confusion and panic, ensuring that occupants have the information they need to respond correctly and stay safe. The use of recorded messages or live announcements can communicate critical information, such as whether to evacuate the building immediately or remain in place, depending on the nature of the emergency.

While smoke detectors, manual pull stations, and emergency lighting are also important components of a fire safety strategy, they do not provide the direct communication and instructions necessary to manage large crowds during a fire incident effectively. Each of these other systems serves specific functions, such as detecting smoke and activating alarms, providing emergency exit signage, or helping with navigation during power outages. However, they lack the integrated communication aspect that is vital in emergencies that involve many people.
