EVAC system

An intelligent evacuation system is a hardware and software solution designed to make individual safety evacuation protocols easier in the event of an emergency. This system establishes a notice and alerting medium that facilitates a smooth and painless evacuation procedure in a range of changing event situations, such as fire, chemical occurrence, extreme weather, and violence.

Bells and sounders only give a warning but do not indicate the nature of an emergency. "A voice alarm system provides controlled and phased evacuation. "Pre-recorded messages in different languages can be automatically broadcast to ensure a safe evacuation. It is also a great asset in case of terrorism or bomb threats as it is not always safe simply to evacuate the building but move people to safer locations within a building."

People are informed about what is happening and what their next steps have to be. Fire officers, building managers, and any other emergency commissioner can broadcast at any time during the situation.

Increased market for automated building solutions drives the growth of the market. In addition, supportive industry standards and regulations pertaining to smart city development fuel the growth of the market.

Under normal circumstances, VA systems serve as public address systems, playing advertisements, background music, and timed message announcements. In emergency situations, however, whether in airports, train stations, or other buildings, voice alarm systems are an essential tool to conduct fast and controlled evacuations, giving instructions and reducing panic.
