Mass notification, paging, and public address systems are used to notify workers, guests or other occupants of a building or an area of pertinent announcements and/or dangerous situations. Speaker systems, visual notification and even telecommunications devices can be incorporated into a mass notification plan for a space. The important factor is getting the message to the correct audience in a quick and clear manner in order to avoid chaos and save lives. Scenarios involving the usage of these systems can range from general announcements, severe weather alerts to active shooter emergencies, with the messages delivered being tailored for the situation.
