I am in an early 1990s block, 4 levels with ground floor parking/storage and 3 levels with 21 units.
As built, the fire “protection” comprised a hose reel on the ground floor connected to the domestic water supply.
Following a fire in the storage area about 12 years ago, the council served orders requiring a 100mm mains riser with hydrants on each level, and an extension of the hose reel system to each level. An automatic diesel powered booster pump and fire brigade booster connections had to be installed for this system. Also, each unit had to be fitted with hard-wired mains powered smoke detectors.
An inspection has to be carried out every 12 months by a certified inspector, who lodges a statement with council.
