Case StudyOverseas Passenger Terminal, Sydney, Australia

Sydney’s Overseas Passenger Terminal (OPT) is

nestled in between the historic Rocks precinct,

the Sydney Harbour Bridge and the Museum of

Contemporary Art, and is almost directly across the water

from the Sydney Opera House.

It’s no wonder then that the venue is rented out for

corporate functions and other events, when ships are not

at berth. The city and harbour views from its premises are

simply spectacular.

Bosch Praesideo System Installed inSydney’s OPT to Serve Growing Cruise Industry

To meet the demands of the booming cruise industry, and

the increasing number and size of ships visiting one of

the most stunning ports in the world, the OPT received a

multi-million dollar upgrade across the last 15-months.

Over $40 million was spent on extensions, renovations

and equipment upgrades. The latter of which included a

Bosch Praesideo Digital Public Address and Emergency

Sound System.

Engineering consultants Umow Lai were asked to design a

public address solution that would help to process larger

numbers of passengers more efficiently. Systems integrator

CNG Systems installed a five-zone Praesideo system where

the resultant loudspeakers optimise the ceiling heights and

room spaces.

Each level of the OPT features an announcement desk that

combines Bosch PRS-CSR control stations, PRS-CSI call

station interfaces and LBB-4432/00 keypads. Programmed

and live announcements are amplified via PRS-1P500 1-ch,

PRS-2P250 2-ch and PRS-4P125 4-ch amplifiers to the

loudspeaker network.

horns greet incoming

visitors walking down the

“gangplanks” to the OPT.

‘These models provide much

higher intelligibility than

standard horns,’ stated CNG

Systems manager

Paul Corbett.

‘This particular application required an extended frequency

range and high sensitivity speaker solution to alert passengers

to get their documents in order and join the correct queue.’

The 4.0 m ceilings in levels one and two are reinforced with

equally spaced EV EViD C4.2 ceiling speakers, whilst the

escalators are served by C8.2HC models. Bosch LBC3099

speakers have been added to back of house areas.

A back of house ELV room combines a Bosch PRS NCO3

network controller and the Praesideo amplifiers, which

creates the de-centralised network facilitating the five-zone

daisy chain configurations. Fully programmed, the redundant

network is also served by three channels of wireless mic

systems and a CD player.

‘Testing and commissioning the system was challenging,’

confirmed Mr Corbett. ‘We had to remain on site until after

3 am on some evenings performing STI tests as there was

continual construction taking place in this reverberant

building. Once we had completed the tests, we were

delighted with the results and the performance of the

system. With the added functionality we have installed in

the OPT, the building can now be used as a multi-functional

space should the need arise.’

Praesideo has a long history of providing EN 54-16 and ISO

7240-16 certified PA and emergency sound system solutions

with over 15,000 installations worldwide. These include

international airports, major train stations, major tunnels,
