Which initiation device is activated by human action such as pulling a lever?

• A. Automatic device
• B. Manual device
• C. Central auto device
• D. Sprinkler device

Answer: (B)

Initiation devices are categorized by what triggers them. When a system is activated by human action, like pulling a lever, it’s a manual initiation device. This type is designed for occupants to deliberately trigger the system—pull stations or manual call points are classic examples. In contrast, automatic devices respond to environmental conditions (heat, smoke, water flow) without human input, so they don’t require pulling a lever.
