A fixed bushfire sprinkler system is a network of sprinklers that are permanently installed around the exterior of a house or building. The system is designed to protect against bushfires by spraying water on the roof and surrounding yard to drench the area and create a moisture barrier to extinguish hot embers before they can ignite the structure.
Our range of double arm heads have been designed specifically for ember defense.
Our heads have the following advantages
Our Australian Made 4 port / 2 Arm Rotary Head, is a robust heavy duty option to imported sprinkler heads.
It protects a 15M Diameter area using 4LPM @ 100KPa, recommended spacing is 6M.
This Brass Head is made by our team in Australia.
No Flow Control I.E pressure drop if the circuit dictates the speed of the sprinkler head, first spins fastest/ last is slowest.

The flow control allows you to slow the spinning rev's to direct more water to the sprinklers down line.
The arm positions are critical to the sprinklers performance. The head needs to rotate clockwise to or a failure will occur as the spindle will undo from the head. We could have used lock-tight on the thread but then you could not dismantle the head during maintenance.
The head will rotate at any angle, we recommend running the tube at the first row of roofing screws above the gutter and setting the heads at 45 degrees. Running the tube on the facia under the gutter and having the heads vertical is another option.
We recommend using an isolator to mount your copper tube, this will reduce galvanic corrosion.
We have Clic isolators in our store for this purpose.
This clip shows an install we completed in 2017, and shows Double Arm Sprinklers running along the ridge line of the house. While we don't install systems anymore we do sell the equipment and can offer advice on setting up a system to defend your home.
