What is the primary function of a fire alarm pull station?

The primary function of a fire alarm pull station is to activate the alarm system. When an individual encounters a fire or smoke situation, pulling the lever or handle on the pull station sends a signal to the fire alarm control panel, which then activates the audible and visual alarms throughout the building. This is essential for alerting occupants to evacuate and for notifying emergency response personnel of the ongoing emergency.

While other options may play roles in a fire safety system, they do not represent the main purpose of a pull station. For example, silencing alarms, monitoring smoke levels, and controlling sprinkler systems are functions associated with different components of a fire alarm or suppression system. The pull station is specifically designed to prompt immediate action in the face of a fire emergency, ensuring that the alarm system is activated and that safety protocols can be initiated effectively.
