NextDC
Walker Fire Protection was engaged by builders FDC to install, commission, test and maintain a new integrated fire protection system, to help keep the critical facility safe.
NEXTDC’s new integrated fire protection system was installed in three 1,000 square metre data halls. Fire alarms, smoke detectors and VESDA® (Very Early Smoke Detection Apparatus) systems were installed for earliest possible detection. The VESDA® reference system also helps to protect the site from external smoke and fire, closing the building’s air intake louvers so that the VESDA® system does not trigger the gas suppression system.
The new gaseous fire suppression system uses Proinert® Gas to stop a detected fire event. The gas is stored in cylinders with 160 initial response gas cylinders installed and another 160 reserve gas cylinders providing back-up, making this one of the largest gas suppression system installations in Australia.
An advanced water mist system was installed in each of the 13 generator rooms, to protect the operation of the Data Centre’s diesel generators. If the heat detectors are activated, high pressure water mist will be released to quickly suppress flames.
