The NMS mass notification system provides real-time information and instructions to people in a building, area, location, or installation by intelligently communicating with visible signals, text, and graphics.

The purpose of mass notification is to protect life by identifying the existence of an emergency situation and informing people of the necessary and appropriate reaction and action.

UL 2572 defines emergency communication systems / mass threat notification systems as follows:

“A configuration of components and interfaces that are used to communicate information to occupants in a building, site area, or other space about emergency conditions.

Systems that consist of equipment that reproduce live and recorded voice messages, tones and visual indicators such as strobe lights and visual displays ”

NFPA 72 defines MNS as follows:

“MNS is provided for the protection of life to give an indication of the existence of an emergency situation and instructing the occupants of the necessary and appropriate response and action.

A mass notification system is considered to be a system used to provide information and instructions to people in a building, area, site, or other space using intelligible voice communications and possibly including signals, text, graphics, tactile, or other communications methods. ”

Mass notification systems are an integral part of emergency and non-accident messages for organizations of all sizes and in all industries.

The key part of the MNS system is a messaging system that provides live or recorded voice communication to staff in a large area.

The mass notification system can also have an anti-terrorist purpose.

Public Address Voice Alarm (PA / VA) integrated with fire alarm systems can be used to provide mass notification to residents of buildings with fire conditions as well as other emergency situations such as weather alerts, chemical spills and terrorist threats. The basic premise of this practice is that it enables the reliability and resilience of Public Address Voice Alarm systems to provide multiple types of communication. This results in high system performance and avoids the additional cost of installing and maintaining multiple systems.

Solutions

Public Adress Voice Alarm systems provide mass alerting to emergency residents. The reliability of the fire detection system makes it a highly effective platform for mass notification. Principles, testing procedures and installation practices are already established. Also first rescuers are already familiar with fire detection equipment, many with years of practical experience. Some fire and life safety systems have expanded their voice communications by introducing mass notification. The system has the ability, via LAN (local area network), WAN (Wide Area Network) or the Internet, to send automated real-time threat messages to many distant locations simultaneously. Essentially, workstations connected to a fire safety system can send alarm messages to one or more locations. MNS can integrate a variety of technologies and devices, including amplifiers, speakers, electronic displays of electronic messages (all monitored for integrity), computer interfaces, emergency calls, commercial radio programs, cable TV and mobile phones. The most advanced solutions use a wireless network or fiber network capable of simultaneously transmitting audio and digital communications over a single fiber-optic band. Mass notification systems work well in disasters. Regardless of whether they respond to a warning of internal security or warn people against a water disaster that can affect building operations in many ways, these systems can save valuable time and allow crisis managers to focus on high priority tasks.
