Which of the following is NOT an automatic initiation device?

A manual pull-station is designed for human activation, requiring an individual to physically pull the lever or handle to initiate an alarm. This contrasts with automatic initiation devices, which activate without human intervention in response to specific environmental changes or conditions, such as smoke, heat, or gas presence.

Automatic initiation devices like smoke detectors, heat detectors, and gas detectors are engineered to sense particular triggers—smoke particles, elevated temperatures, or hazardous gas levels—and respond by sending alerts or activating alarms automatically to ensure prompt action can be taken to address potential hazards. Understanding the distinction between automatic and manual devices is crucial for effective fire safety planning and response.
