Automist® is an easy to install alternative to home fire sprinkler system

Automist must be installed by one of our Accredited Installer Resellers and can take as little as 2 hours. Automist was designed with retrofit in mind. Easy installation is, in part, due to the use of flexible high pressure hose which do not need to go through the ceiling because of the position of the spray heads.

Preparing the site


Sufficient space to install the pump. The pump is 15" (height) by 10" (depth) by 8" (width) and weighs 15.4 pounds, and should not be housed in a volume of less than 4.38 ft3.

A reliable cold water supply (1.6 gpm flow and 14.5 - 145 psi pressure).

Automist should be powered by an unswitched fused connection unit connected to an independent electric circuit.

Install the spray head

The Automist Faucet emitter can be installed within a standard 1 3/8" hole (under a faucet), or Smartscan can be wall mounted affixed into a rectangular hole (3.5" wide x 4.6" high) that is at least 2.2" deep when using the “old work” clips provided. The Smartscan emitter must be installed between 3.9 - 4.6 ft from the ground.

water supply

Connect the water supply

Position the pump as close as possible to the mains water supply pipes. Connect the high pressure hose from the assembled emitter to the outlet on the pump. Connect the water supply with an approved isolation valve to the check valve and filter. Finally, connect the check valve outlet to the pump inlet.

Connect the electrics

Connecting the power to the electrics requires a suitably qualified & competent person. Switch off electricity at the mains before working on existing circuits.

Commissioning is a procedure which allows Automist to be tested. During commissioning, the pump runs for approximately 20 seconds and the output pressure is monitored. A test shield is provided to direct the resulting spray into an adjacent sink or within a bucket.
