BLAZESTOP can be connected to either a local authority domestic water connection, or to a storage tank and pump system.
Ideally BLAZESTOP should be installed in as many rooms as possible. However, you may be able to
dispense with outlets in voids or spaces above ceilings or below floors, toilets and bathrooms, garages that are connected directly to the home, wardrobes or cupboards.
The maximum spacing between sprinklers depends on the type of sprinkler head you choose; the minimum spacing is 2400mm. Light fittings, beams or lintels that may obstruct the spray pattern need to be taken into account.
Piping design must minimise dead-legs to sprinklers and fixed directly behind the sprinkler heads. BLAZESTOP does not require a backflow prevention device or inline pressure gauge. The design must comply with NZBC Clause G12 Water Supply and be lodged with the Building Consent documentation.
After installation, the system must be pressure tested at 1500kPa for at least 30 minutes, although the
pressure may need to be reduced if other products are to be included in the test. A MHD (Most Hydraulically
Disadvantaged) Sprinkler verification test must be conducted to ensure that the design pressure and flow are achieved at the MHD sprinkler heads.
Please note: this information is only a summary. Your plumber will need to contact a LEAP supplier for a copy of the Installation Manual which has other important information.
