What is the term for a manual fire alarm initiation switch that requires two separate actions to activate the alarm?

• A. Double action pull station
• B. Single action pull station
• C. Push-button alarm
• D. Manual call point

Answer: (D)

Requiring two separate actions to activate the fire alarm describes a two-action, or double-action, manual initiation device. This design helps prevent accidental alarms by needing an intentional sequence, such as first lifting a protective cover and then pulling the handle, or pushing and pulling in two steps. A double-action pull station is specifically built for that two-step process. In contrast, a manual call point generally refers to a manual activation device that activates with a single action—like pressing a button or breaking glass. So the term for a device that needs two actions is a double action pull station.
