The project has been designed by the RCF Project Design Office, based on the original design made by Sergio Berno from the EL Engineering Service of Turin. The installation has been completed by Orion Gesta under the supervision of engineer Ivan Catellani.
The main audio system is the RX4000, a completely integrated system for voice evacuation, paging and background music and is EN 60849 CEI 100-55 compliant.
The main control unit manages two more units, located in other parts of the building and are connected to the first through Cat 5e UTP cable. All three units are equipped with boards for the diagnostic of the amplifiers, and the speaker line and microphone consoles.
The two slave units are also equipped with EOL boards to check the connection with the main central unit. Three different banks of recorded messages are controlled by the central unit.
The audio system has been divided into 11 zones, managed entirely by the main unit, CP4100, that process's and sends all the standard paging an emergency calls that come directly from the fire alarm system.
To amplify the sound in the four corridors that start from the main hall, DU100X have been used.
To minimize the visual impact of the speakers in such an historic palace, the Orion Gesta installers have hidden them inside fireplaces or niches in order to preserve the integrity of the richly painted a fresco walls.
