A Mass Notification System or some say a “High Power Siren System” or “Mass Warning System” is for critical infrastructure/facilities that are at risk of experiencing a major incident and have a broad impact not only on the infrastructure area but also on the surrounding community. 

Mass Notification System, is urgently needed to provide warnings to be able to provide information on the actions needed during evacuation to reduce the impact of loss of life Proper sound coverage area calculation analysis should be carried out during the engineering stage to ensure that the Mass Warning System has an appropriate sonic sound before the operation, but not detrimental health.

The Mass Notification System is not only intended for the community around the infrastructure but also for people who are in the infrastructure/facilities, therefore it is sometimes necessary to install a device that can be seen as a beacon. 

The effect of the Mass Notification System on the surrounding community is quite large, it will usually be connected to the government’s Mass Notification System as an early warning device so that residents can be immediately warned and evacuated according to the instructions of the local government authority. Therefore, in infrastructure/facilities that have the potential to cause a major impact on the surrounding environment, such as Petrochemical, Oil and Gas, Nuclear Power Plants, and so on, it is necessary to install a Mass Notification System (Siren System) with a superior power output that can produce sound with wide coverage but does not interfere with hearing health.

A Mass Notification System is constructed with one or more loudspeakers designed and constructed to provide superior audio quality. In application Mass Notification System can be installed;

• Government warning systems for tsunamis, wars, earthquake impacts, etc. Usually used in cities that have a large enough potential for danger.
• Mass Notification System for dam safety and flood warning – when there is a risk of flooding, Dams can present a fundamental risk to the people living in the vicinity.
• Oil & Gas, Petrochemical, Refinery, and Power Generation.
• Other infrastructure that has a big impact on the surrounding community
