What does a Double Action fire alarm pull station require to activate?

A Double Action fire alarm pull station is specifically designed to enhance safety by requiring two distinct actions to activate the alarm. This feature is intended to prevent accidental activations that could lead to unnecessary evacuations or disruptions. The need for two actions means that an individual must first pull down a handle or lift a cover before pulling the alarm lever or handle again. This design minimizes the likelihood of false alarms and ensures that only someone who is certain of the need for evacuation will activate the alarm. It’s an important safety measure in environments where false alarms can cause panic or operational disruptions. Thus, the requirement of two actions confirms the station's purpose of ensuring that the alarm is intentionally used.
