What is a "pull station" typically used for?

A pull station is primarily designed to manually activate the fire alarm system in a building during an emergency situation. When an individual notices signs of a fire or another emergency, they can pull the handle on the pull station to sound the alarm, prompting immediate emergency response and alerting occupants to evacuate. This quick action can be crucial in reducing response time and possibly saving lives.

The other options do not align with the primary purpose of a pull station. Unlocking emergency exits is typically managed through specialized hardware or systems designed specifically for that function. Distributing fire safety pamphlets is an educational activity that does not involve the mechanics of alerting emergency services. Signaling normal operating conditions does not apply to a pull station, as its function is to indicate an emergency, not normalcy. Thus, the focus of the pull station is squarely on alerting individuals to danger and activating the fire alarm system effectively.
