A fire alarm and detection system is designed to detect and alert occupants of a building in the event of a fire. Fire alarm and detection systems are essential for protecting lives and property in the event of a fire. They can provide early warning of a fire, giving occupants time to evacuate the building and allowing firefighters to respond quickly. It is important to ensure that these systems are properly installed, maintained, and tested to ensure that they are functioning properly and can effectively protect a building and its occupants in case of a fire.
