Public Address Systems provide one-way communication with the goal of quickly disseminating information about an imminent or developing emergency situation.

Public Address or Voice Alarm (PA/VA) Systems

Public address or voice alarm (PA/VA) systems are electronic sound amplification and distribution systems comprising microphones, amplifiers and loudspeakers that are capable of broadcasting live and pre-recorded messages, tones or alarm.

Different types of loudspeakers are available:

 Ceiling speakers

 Wall mounted speakers

 Horn speakers

 Spherical speakers

 Sound projectors

In safety applications, PA/VA systems are used as an emergency notification system when it is of paramount importance that inhabitants and rescue teams are given timely warnings and accurate information conveyed via crisp and clear audio. This enables people to be safely directed towards safety shelters and evacuation routes and away from the hazard.

Simpler PA/VA systems are used in small venues such as school auditoriums while large PA/VA systems comprising several speakers are used in industrial, government, transport (airports and trains stations) and residential building complexes and in other large areas such as university campuses, stadia, public grounds, etc.

PA over IP: Fully digital, networked, PA/VA systems are also available that use an IP network instead of a centralized amplifier to distribute audio signals. Unlike traditional PA/VA systems, these IP systems offer greater flexibility in system design (can be easily programmed to dynamically group PA zones), interference-free audio and a high level of redundancy for uninterrupted operation. They can also be interfaced with other security systems such as access control, CCTV, etc. for a more comprehensive safety solution.

Ideal for use in:

 Airports, train stations, bus stations, seaports



 Schools and colleges

 Office complexes

 Shopping malls
