Flashcards

What is a fire detection system?

A system designed to identify fire or smoke in a building. Includes smoke detectors, heat detectors, flame detectors, and fire alarm control panels.

How do smoke detectors work?

They use optical or ionization sensors to detect smoke particles in the air. Triggers an alarm when smoke is detected.

How do heat detectors work?

They activate alarms when a predetermined temperature threshold is exceeded. This indicates the presence of fire.

What is a gaseous suppression system?

A system that uses inert gases or chemical agents to extinguish fires by displacing oxygen or inhibiting the chemical reactions that sustain combustion.

How does a sprinkler system work?

Sprinkler systems consist of a network of pipes with sprinkler heads strategically placed throughout the building. When heat from a fire activates a sprinkler head, water is released to suppress the fire.
