Answer:
The main components of a fire alarm system include:
Detectors: Detectors are devices that sense the presence of fire and trigger an alarm. There are two main types of detectors: smoke detectors and heat detectors. Smoke detectors detect smoke particles in the air, while heat detectors detect a sudden rise in temperature.
Alarm devices: Alarm devices are devices that alert people to the presence of a fire. They can include audible alarms, such as bells and sirens, as well as visual alarms, such as strobe lights.
Control panel: The control panel is the brain of the fire alarm system. It receives signals from the detectors and triggers the alarm devices when a fire is detected.
