• Fire detection , smoke , rate of heat rise , and beam detectors were utilised to quickly detect and alarm fire conditions . The quick alarming and actioning of fire scenarios is key to the
maintenance of the building in event of fire .
• A public address and audio-visual system ( fire rated ) was installed to enable full audio control of the site .
• A security room , control room and data centre would be the hub of monitoring for all services .
• Dual redundant dedicated air conditioning was provided via heat pump splits .

Fire engineering services were also included in the project that comprised hydrants and hose reels to the full coverage of the building with 30m length reels , one hydrant per 1000m 2 ( 90m coverage ), sprinkler system as the building is over 30m in height the US , British and South African standards thus require sprinklers , water storage and pumping including controls thereof , and fire protection equipment .
The fire system bulk plant allocations for this project , located below the car park ramp and in adjacent parking at level B2 , included the sprinkler tank ( sectional steel / concrete ) with a 196 000 litre ( partitioned ) capacity , hydrant & hose reel tank ( sectional steel / concrete ) with a 25 000 litre ( partitioned ) capacity , and a valve chamber 1m x 5m .
