A fire siren is an audible alert system used to notify people of a fire emergency. It emits a loud, distinctive sound that can be heard over a considerable distance, typically signaling the need for evacuation or alerting firefighters to respond. Fire sirens are strategically installed in buildings, public areas, and sometimes mounted on emergency vehicles. They play a crucial role in ensuring prompt evacuation and coordinated response during fire incidents, helping to minimize risks to lives and property. Fire sirens are often integrated with fire alarm systems and are designed to operate reliably even in adverse conditions, enhancing overall fire safety preparedness.
