Fire alarm systems are designed to detect and alert occupants to the presence of fire or smoke in a building. They typically consist of smoke detectors, heat detectors, alarms, and control panels. The main purpose is to provide early warning so that people can safely evacuate the building and take action before the fire spreads.

These systems also notify emergency services, reducing response time and minimizing damage. Fire alarm systems help ensure the safety of building occupants and comply with fire safety regulations.
