A fire alarm serves four primary purposes in fire safety and emergency response: Early Detection of Fire: The foremost purpose of a fire alarm is to detect the presence of fire as early as possible. Fire alarms are equipped with smoke detectors or heat sensors that are designed to identify the initial signs of a fire, such as smoke particles or rising temperatures. By detecting fires in their early stages, the alarm provides crucial time for occupants to evacuate the premises and for emergency responders to take necessary actions promptly. Audible Alert for Occupants: One of the most important functions of a fire alarm is to provide an audible alert to occupants within a building. When a fire is detected, the alarm system activates loud sirens , bells, or horns, alerting individuals of the potential danger. The loud and distinct sound is designed to grab attention and initiate immediate action, urging occupants to evacuate the area or follow predetermined emergency procedures. Visual
