Fire Alarm System
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings.
The four most common detectors are ionisation, photoelectric, combination ionisation/photoelectric, and heat. All smoke detectors sound an alarm, when they identify smoke, to notify a building’s occupants. What differentiates these detectors from one another is the way that they detect smoke.
