Audio over IP public address for MoD St Athan

Vaughan Sound has successfully installed a site wide, audio over IP public address system at the Ministry of Defence’s St Athan site.

A joint venture between estates and facilities management giants Amey and Carillion – which was awarded three massive regional contracts together worth up to £2.8bn – led to our appointment on this high profile project.

Our team was subsequently tasked with delivering one of its most complex installations to date. Complying fully with the MoD’s stringent Manual of Regulations for Installation of Communication & Information Systems, Vaughan Sound integrated almost 7,000 metres of fibre cable and 112 IP67 rated DNH external horn loudspeakers, to create zones covering 30 individual buildings.

Each building contains a 9U rack incorporating a 100v line power amplifier, 24-port fibre switch and a network IP addressed fire alarm interface.

The public address is accessed and managed via a Creston 3-Series® Control System with custom GUI. This has been combined with 2N® NetSpeaker solutions, two paging microphones with touchscreens, plus a PC server. The functionality allows for the selection of any individual zone or group of zones as required.

Raymond Isaac, Senior Project Manager (South) at CarillionAmey said: ”From our initial brief to the handover and completion, Vaughan Sound were very professional and efficient.

“Working in a highly secure environment the team was very proactive and dedicated.

“The end result was very well received by our client and end users.”
