Emergency alarms are devices designed to alert people to potential dangers, such as fires, intrusions, or other emergencies. They can be found in homes, businesses, and public spaces, and often use loud sounds, flashing lights, or both to grab attention. Common types include smoke detectors, carbon monoxide alarms, and security alarms. When an emergency alarm is triggered, it serves as a warning to evacuate or take protective actions. Many systems are connected to monitoring services that can notify emergency responders, such as firefighters or police, ensuring a quick response to the situation.
