Public address system is a centralized amplifier based system that’s been designed to provide voice paging and to broadcast alarm tone during emergencies.

The system can transmit alarm tone and routine voice messages, from a central location, to all or selected areas of the facility, in a reliable and safe manner, by the use of loudspeakers. The entire operational area / facility can be divided into one or more zones, which can be accessed independently either for announcements or for alarm broadcasting. The loudspeakers are installed in these zones.

There are no limitations to number of zones in the system or number of loudspeakers in each zone. Each loudspeaker is connected to the central equipment for amplification and other control functions.
