What type of systems are typically used to alert occupants of a fire?

Fire alarm notification systems are specifically designed to alert occupants in the event of a fire. These systems include devices such as smoke detectors, heat detectors, manual pull stations, and notification appliances like horns, strobes, and speakers. Their primary function is to quickly and effectively communicate the presence of a fire, ensuring that occupants can take the appropriate actions to evacuate safely.

While ventilation systems play a crucial role in controlling smoke and heat during a fire, they do not serve as a means to notify occupants. Security systems are focused on protecting property and individuals by preventing unauthorized access and monitoring alarms related to security breaches, not fires. Communication devices may assist in relaying information during an emergency but are not dedicated to fire alerts. Thus, fire alarm notification systems are the most direct and relevant choice for alerting occupants of a fire.
