MEDIA RELEASE
Real Time Tunnel Vision Gives Sydney Harbour Tunnel New Advanced
Fire Detection System
Sydney, Australia, 20 October 2009 The Sydney Harbour Tunnel Company (SHTC) has invested in
an upgraded
digital video fire detection system which will go live next month, providing early
smoke and flame detection throughout the 2.3km long, four lane tunnel.
Accurate and reliable smoke detection in road tunnels is notoriously difficult due to the twin problems of
near continuous air movement and exhaust fumes from vehicles. However the upgraded FireVu Video
Smoke Detection
system, from Chubb Australasia,
can see
the source of smoke and/or flames,
identifying them anywhere within its field of view. This early at source detection is faster than other forms
of detection as it is not waiting for the smoke to reach the detector.
Bob Allen, General Manager of Sydney Harbour Tunnel comments, Our original system at the time of
opening in 1992, was based on thermal detectors with a rate of rise algorithm which of course meant long
delays before an alarm condition was reached.
With advances in technology, we are always looking for the most effective systems of fire detection to
ensure the best possible safety levels are in place. We cannot afford to be complacent.
The new FireVu
system
is
being installed at the North Sydney control centre and the existing VSD-8
system is being transferred to an emergency control room in Bradfield Park. The emergency control room
has been designed as a back up to the North Sydney facilities. The VSD-8 and FireVu system installed by
Chubb Australasia over the last four years represent a half a million dollar investment by Sydney Harbour
Tunnel Company.
Shaun Smith, Business Development Manager, Chubb Australasia comments, The FireVu system has
proven to minimise potential fire risks extremely effectively for large facilities and its adaptation for the
Sydney Harbour Tunnel is an ideal application. FireVu, based on Anglo Designs (AD)
NetVu connected
Generation 3 platform, operates over an IP network and has been retrofitted to 80 of the tunnel's CCTV
cameras 40 in the north bound, 40 in the south bound tunnel - to provide a rapid identification of potential
fires.
FireVu works by using standard CCTV cameras as sensors. The video information fed into FireVu uses
extensive algorithms to analyse pixel movements. Should the motion patterns be recognised as smoke
and/or flames, the system will generate an alarm.
It has the ability to use image-processing technology
to
alert the system operator to the presence of
smoke/flame
in the shortest possible time -
this is especially critical in a confined tunnel environment.
Unlike traditional methods, by effectively detecting smoke at source, FireVu does not rely on the proximity
of smoke/flame to the detector and is therefore unaffected by distance.

An operator can use a standard PC (with viewing software loaded) to view individual or multiple camera
images in real time. When an event occurs, a live image showing clear boundaries of the alarm area is
displayed to the operator with the option to view pre-event recorded footage, invaluable in reacting to the
incident in the quickest and safest way.
All alarm events are recorded to disk with configurable pre and post event video, allowing the operator to
witness (and download) the event, including who or what created it.
The system has been trialled
by
the
Sydney Harbour Tunnel Company
running a series of controlled
vehicle fires in the tunnel with the assistance and oversight of the New South Wales Fire Brigade. These
exercises were created to demonstrate
the tunnel's exhaust system's ability to remove smoke, the
activation of the point detectors, and the capability of the deluge system to suppress a fire. FireVu alarms
were activated within seconds of visible smoke and prior to visible flames.
The FireVu solution is capable of providing real time Video streams from all cameras which are stored on
the units onboard configurable hard drives. For the Sydney Harbour Tunnel the FireVu hardware transmits
its alarm signals to the dedicated Chubb NFP2 fire panel within the tunnel control centre in North Sydney.
Bob Allen says, Our approach is risk averse and the new FireVu not only provides us with earlier detection
capability but also minimises what we call nuisance (false alarm) calls. The technology is second to none
but we cannot overlook the monitoring and essential manual backup from our dedicated 24-hour manned
control room. Working together we have the best fire protection system in place.
