In fire alarm systems, what does the term "active device" refer to?

The term "active device" in fire alarm systems specifically refers to a component that detects or responds to fire conditions. These devices are essential for the immediate response to potential fire emergencies. They include smoke detectors, heat detectors, and manual pull stations, all designed to sense dangerous situations and trigger alarms or activate suppression systems to mitigate the risk of fire.

Active devices play a crucial role in fire alarm systems by ensuring that any signs of smoke, heat, or flame are promptly identified, allowing for timely alerts to occupants and emergency services. By facilitating quick reactions, these devices help safeguard lives and property in the event of a fire. Their operation is generally automatic, functioning without the need for manual activation in most scenarios, which further enhances their effectiveness in fire prevention and safety.
