Design, Supply and Installation of Public Address Systems

What is a Public Address?

Public Address Systems, PA Systems or “Tannoy” systems can be used to transmit public announcements throughout a building or to individual areas on a zone by zone basis.

Public address systems can also include class change timers for schools using a siren, bell or any other sampled sound required. Background music can be added to any public address system.
