Automist an easy to install home fire sprinkler system
  • loft void


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. It also does not require a commerical grade water main or a tank.

Installation Procedure

Preparing the site


Sufficient space to install the pump. The pump is 366 mm (height) by 216 mm (depth) by 151 mm (width) and weighs 7.0 kg, and should not be housed in a volume of less than 0.124 m3.

A reliable cold water supply (5.6 lpm flow and 1 to 10 bar pressure) with a standard BSP 3/4" connection.

Automist requires an independent electrical supply, not shared with other unrelated devices via an unswitched fused connection unit (FCU).

Install the spray head

The Automist tap head should be installed within a standard 35mm hole, Automist fixed head is wall mounted in a standard single-gang mounting box and Automist Smartscan is affixed in a custom wall mounting box.

Connect the water supply

Position the pump close to the mains water supply pipes. Connect the high pressure hose from the assembled emitter to the outlet on the pump. Connect the 3/4” 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 into a bucket.
