A manual fire alarm can be activated by using a "pull station." Pull stations are strategically located throughout buildings to provide a quick and accessible way to alert others of a fire emergency. When an individual sees signs of a fire, they can pull the lever on the station, which sends a signal to the fire alarm system, activating alarms throughout the facility and alerting occupants to evacuate.

While other options might contribute to alerting others about a fire or initiating a response, they do not directly trigger the fire alarm system. For instance, calling 911 is important for notifying emergency services but does not activate the building's alarm. Similarly, a large amount of smoke might be a reason to activate an alarm, but it does not do so directly, as it relies on smoke detectors or similar systems. Breaking the glass of a fire extinguisher casing is a reckless act that is not intended to activate the fire alarm and can lead to confusion during a fire emergency. Thus, utilizing the dedicated pull station remains the correct and intended method for manual activation.
