Automist Installation Information and Requirements

First Fix

First Fix Stage – BCK Supply and install the high-pressure hoses and Wired/Wireless Heat Detector/s, this may include chasing the walls or cutting into the plasterboard as shown on the image below


Commissioning Stage – BCK Supply and install the Smartscan Hydra Pump/s, Controller/s and Head/s, Water and Electric need to be on and working in order for us to commission and all the items shown on the “Automist Requirement” list need to be in place.


Please Note: We advise that plastering and painting need to be done before commissioning stage.

Electrical Supply 

  • Independent power supplies from the distribution board using a RCBO C16 Breaker per pump in FP200 2.5mm 3 Core Cable (2 core + Earth) or better, ideally inside conduit or protected 50 mm deep within a wall

  • Unswitched 13-amp Fused Spur, it must be adjacent to each pump


The Above Needs to be Installed by a Certified Electrician

We will need a copy of the Electricians Installation Certificate

Water Supply

  • Water supply with a 3/4” washing machine tap on each connection for each pump

  • The cold-water supply must deliver adequate flow and pressure. 

    • Minimum 8 litres per minute flow

    • 1.5 – 6 bar pressure static water pressure

  • Water supply needs to be 400mm from the floor and at least 80mm from wall so we can fit the filter and pump connectors. (please see example photo below)

Pump Sizes

  • H 365mm x D 240mm x W 181mm

  • Please allow adequate room for the connections at the rear of the pump at least 200mm in the back and 100mm in the front and sides.

Smartscan Hydra Head

  • The Automist sprayhead is mounted at a height of 1200 - 1450mm from floor level in a kitchen and 1400 - 1450mm from the finish floor level in all other rooms.

  • The lower height in the kitchen is for better targeting of the significant fire risks; white goods and the hob/cooker in a room assuming a standard worktop height of 900mm high.

  • The Head is designed to be affixed into a hole 90mm wide x 117mm high and 57mm deep.

  • If using a Back Box, the hole dimensions area as follows 95mm wide x 120mm high & 60mm deep

  • IMPORTANT! The Automist Smartscan Hydra head must be located where the spray pattern will not be obstructed and 1500mm horizontal clearance provided 180 degrees around the sprayhead.

Cables & Hoses

  • Cables installed at first fix in the ceiling need to be visible when we return to commission so the engineer can connect to heat detectors

  • Once client has plastered and painted and ready for commissioning the system, the high-pressure hoses installed at first fix will need to be loose in the wall cavity so our engineers will be able to pull it out of the wall at least 2 inches to install the head

Multi-Sensor Detectors

All estimates are based on Wired Multi-Sensor Detector/s to be installed, if the project is a retrofit, to save cutting ceilings to install the Cable for the Detectors you or our installers may request “Wireless Detectors” which will be at an additional cost per detector. (Ask the engineer for the price or contact the office)

IMPORTANT! These detectors are what activates the Smartscan Hydra Head and are separate to any other Fire Detection you may have in the property.
