Page 11: Specifying Automist
S M A R T S C A N Specifying Automist Automist design specification guidelines state that a single pump can cover an area of up to 32m , with a maximum ceiling height of 3.5m. Based on third party test data, spray heads must be located within 5m line of sight of any possible fire location.
Page 12 Building Control or other involved third parties. Automist is accepted for use as a compensatory measure for loft conversions where an open plan ground floor layout exists. The applicable regulatory guidance is given in paragraph 2.20.b of Approved Document B (Fire safety) –...
Page 13: Room Compatibility
Room Compatibility A single Automist pump unit was tested by Exova Warrington in an area of up to 32 square metres (2.5m ceiling height) with fire hazards up to 5m away. The spray head should therefore be within 5m of & in the approximate line of sight of any fire hazards.
Page 14: Spray Head Placement
• Spray Head Placement The Automist Head is designed to be affixed to a standard 50mm deep single-gang mounting box (85mm x 85mm with fixing centres offset centre to centre by 60mm). IMPORTANT: The Automist head must be located where the spray pattern will not be obstructed and 750mm clearance is provided adjacent to each of the active nozzles.
Page 15: Detection System
DO NOT trigger Automist from a smoke alarm as this will lead to unwanted activations. • DO NOT connect the Automist pump’s alarm input to any device other than a volt free relay. In • particular, connecting the three coloured cables to the alarm interconnect or to any power supply whatsoever is likely to damage the Automist pump beyond repair.
Page 16 BS5839-1:2013 section 22.3. Notably this implies a working range of no more than 5.3m for heat alarms and gives guidance on unusual ceiling types. Automist’s use of heat alarms does not affect or reduce any requirements for the use of smoke •...

Page 19: A) Preparing The Site
The circuit supplying a single Automist unit would commonly be protected by a type ‘C10’ or ‘C16’, for example, or ‘C20’ / ‘C32’ for two Automist units. This should be on a C-type breaker, on an RCBO or a RCD protected circuit.

Automist system. Many options for such an alarm are available and Plumis recommends the purchase of an inexpensive alarm from Amazon, using the following link: https://www.amazon.co.uk/gp/product/B01GE3NDB4/ref=pd_cp_107_1?ie=UTF8&psc=1&refRID=REA5Y9F0R...
Page 21: C) Installing The Automist Head
The manifold is set up with 2 x A16 nozzles and 2 blanks. C) Installing the Automist Head IMPORTANT: When installing an Automist head with four nozzles you must make sure the active nozzles are pointing into the room and not towards the wall. PTFE tape should be wrapped approximately three times around the hosetail thread that enters the spray head.
Page 22 IMPORTANT: Make sure the hose is slack enough to allow easy removal of the head for commissioning. This may require use of a conduit in some wall types. Plumis Ltd Copyright © 2017. All Rights Reserved. Page 22 of 41...
Page 23: D) Connecting The Water Supply
Automist pumps and the normal domestic supply in its worst condition. Otherwise a priority valve or a booster pump may need to be used to provide the required flow and pressure. It is responsibility of the installer to ensure the water supply to the Automist pumps is adequate.
Page 24 IMPORTANT: If new pipe has been fitted remember to flush out any contaminants before connecting to Automist, to avoid clogging the nozzles. Connect the high pressure hose from the assembled head to the outlet on the pump. Plumis supplies suitable high-pressure hoses. If using another brand of hose, follow Plumis’s guidance note, available on the Plumis Partner Site.
Page 25 IMPORTANT! To comply with water regulations, an approved isolation valve must be used when connecting the check valve to the mains. A cable tie is provided to tie the Automist supply pipe label to the isolation valve. The warning label must be visible but must not obstruct isolation valve operation.
Page 26: D) Connecting The Electrics
Using a conventional wrench, apply another 1/2 turn clockwise to guarantee a reliable seal. D) Connecting the electrics IMPORTANT! The Automist pump should be positioned in a safe and dry location where it is easily accessible, the button will not be pushed accidentally, and the front panel remains visible when the access door is open.
Page 27 STOP button is inaccessible. Where required, the loop should be cut and each end of the wire connected via FP200 cable to a momentary action, normally closed, push button switch (see diagram below). Plumis Ltd Copyright © 2017. All Rights Reserved. Page 27 of 41...
Page 28 S M A R T S C A N The button should have an appropriate IP rating (e.g. IPX5 if used in the room protected by Automist), located as close to the pump as possible and should be clearly labelled. The auxiliary button cannot be used to commission the unit but can be used to enter ALARM TEST MODE (see page 30).
Page 29: E) Commissioning And Maintenance
Commissioning must be performed by an Accredited Automist Installer yearly. When Automist is powered up for the first time the yellow FAULT LED will indicate that the system has not been commissioned. Commissioning is a simple programmed procedure which allows Automist to be tested.
Page 30: The Automist Controls
The Automist Controls STOP Button: Pressing the STOP button during a fire condition will stop the Automist pump for 2 minutes. If at the end of 2 minutes, an alarm input remains active, Automist will recommence mist operation. If the alarm condition has ended, Automist will return to stand-by.
Page 31 By leaving an installed system with pressures outside the specified range, you might become liable for deaths or injuries. If the achieved output pressure is outside the specified range, refer to the commissioning troubleshooting guide (see page6) and contact Plumis on 020 7871 3899 if the situation cannot be resolved.
Page 32 Carefully remove the test hose and gauge and re-attach the cap on the test point adapter. Following a successful pressure test, the high pressure hose must be cleared of water by connecting a suitable pump to the Plumis supplied attachment, that is connected to the test point tee.
Page 33: Power Supply
Automist should be supplied using FP200 cable or better, ideally inside conduit or protected 50mm deep within a wall • Automist may be protected by an RCD or RCBO but this protection must not be shared with other circuits. Therefore Automist should be connected to the non-protected side of the consumer unit. •...
Page 34: Alarm Relay Placement
The Installer Commissioning form should have been provided (can be obtained from Plumis or the installer) with a matching layout drawing The Plumis Warranty Certificate is provided (can be obtained from Plumis) once the layout has been submitted and approved by Plumis.
