A fire alarm system is a safety mechanism designed to detect and alert people to the presence of fire or smoke. It typically consists of various components, including smoke detectors, heat detectors, and manual pull stations. When a fire is detected, the system activates alarms to warn occupants and may also notify emergency services. These systems can be found in residential, commercial, and industrial buildings, ensuring the safety of occupants by providing early warning. Regular maintenance and testing are essential to ensure that the fire alarm system functions properly in case of an emergency, helping to prevent loss of life and property damage.
