When this product has reached the end of its serviceable life, it should be disposed of in a safe • manner. IMPORTANT: Once installed, complete and submit an installation and commissioning form to Plumis. WARNING: To avoid hazards, all installation procedures and maintenance must be supervised by an Accredited Automist Smartscan Installer.
Page 6: Automist Smartscan Operation
The high momentum vertical spray orientation with a horizontal trajectory ensures that even shielded fires are saturated with a turbulent flow of mist, suppressing the fire. In the event of a fire, Automist Smartscan is triggered automatically by a relay contact, provided by one or more heat alarms/detectors,...

Page 12: Protected And Shadowed Areas
Protected and Shadowed Areas Automist Smartscan will only operate at its maximum effectiveness when spray heads have collective visibility of all fire loads throughout the entire room to be protected, with a minimum of obstructions by furniture or indeed doors.
Page 13: Preferred Positions" And Avoidance Of Potential Obstructions
Adjust until the effective shadow area is below the maximum square metreage for the project type (see below). The diagram (later submitted to Plumis) should show the Effective Coverage Area and state its area in square metres for each compartment to be protected.

Page 21: Areas Not Required For Coverage
Indirect Coverage Because Automist Smartscan is activated only by heat detectors, the fires that it must tackle are inherently quite well-developed. Tests with obstructed views of fires have shown that a partial view of the developed fire is sufficient for Automist Smartscan’s sensor to locate the fire correctly, and that turbulent spray flow...

In Figure 16 (detail in Figure 17) the shadow area is reduced to the Effective Shadow Area by expanding the actual coverage by 0.3m in all directions (to allow for Indirect Coverage).

Page 26: Use Of These Rules
Plumis accredited installers are trained to specify, install, commission and maintain the Automist Smartscan system. Their early involvement in the project is recommended as they are required to verify installation proposals, provide critical supporting technical information and also commissioning certificates for project approval by Building Control or other involved third parties.

A cold water supply which can deliver 6 litres per minute flow at a minimum of 1 bar (100kPa) and a • maximum of 10 bar (1MPa) static pressure. If multiple Automist Smartscan units are to operate simultaneously, a proportionately higher flow will be required.
Page 29: Spray Head Placement
S M A R T S C A N Spray Head Placement The Automist Smartscan Head is designed to be affixed into a rectangular hole (89+/-2mm wide x 117mm high) that is at least 57mm deep when using the “old work” clips provided.
Page 30 DO NOT trigger Automist Smartscan from a manual call point. • DO NOT connect the Automist Smartscan 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 Smartscan pump beyond repair.
Page 31 Ensure Automist Smartscan is only connected to the main heat alarm(s) in the volume it protects. You can check these interconnections using the product’s ALARM TEST MODE (see page 44). In this mode, the alarm lamp will light to indicate a functioning alarm input.
Page 33: Installation Procedure

Page 34: A) Preparing The Site
Components of the fire detection and alarm system may use this circuit, which must remain powered in the event of a fire. Power to Automist Smartscan must be provided via an unswitched fused connection unit (FCU). Automist Smartscan should be supplied using FP200 cable or better, ideally inside conduit or protected 50mm deep within a wall, and with no RCD or RCBO protection.

Page 38: C) Connecting The Water Supply
IMPORTANT: If new pipe has been fitted, remember to flush out any contaminants before connecting to Automist Smartscan, to avoid clogging the nozzle. 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 39 Test Point o-ring The Automist Smartscan pump unit should be housed close to a 3/4” BSP water supply with an approved isolation valve to the check valve. A synthetic rubber washer is supplied with each device to facilitate fitting to the flat-faced outlet.
Page 40 Note: If the filter has a paint mark running over the cap and body (as in the image below), then the o-ring has already been lubricated and the connection adequately made by Plumis. Plumis Ltd Copyright © 2017. All Rights Reserved.
Page 41: D) Other Electrical Connections
For installations that require a wireless relay receiver, position the relay base on the wall next to the Automist Smartscan pump unit, as close as possible to the front of the cupboard door. IMPORTANT! Connecting the power requires a suitably qualified & competent person. Switch off electricity at the mains before working on existing circuits.
Page 42 Handbook v1.2.3 S M A R T S C A N General wiring arrangement for Automist Smartscan. In most installations the remote STOP is not installed and the associated wire loop remains intact as supplied. The Smartscan spray head connects to the pump using a Smartscan Head Cable as specified above (p35).
Page 43 (see diagram above). The button should have an appropriate IP rating (e.g. IPX5 if used in the room protected by Automist Smartscan), 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 49).
Page 44: E) The Automist Smartscan Controls
E) The Automist Smartscan Controls STOP Button: Pressing the STOP button during a fire condition will stop the Automist Smartscan pump for 2 minutes. If at the end of 2 minutes, an alarm input remains active, Automist Smartscan will recommence mist operation.
Page 45: F) Commissioning And Maintenance
Commissioning must be performed annually by an Accredited Automist Smartscan Installer. When Automist Smartscan is powered up for the first time the yellow FAULT LED will flash twice to indicate that the system has not been commissioned. Commissioning is a simple programmed procedure which allows Automist Smartscan to be tested.
Page 46 020 7871 3899 if the situation cannot be resolved. 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.

50mm deep within a wall • Automist Smartscan may be protected by an RCD or RCBO but this protection must not be shared with other circuits. Therefore, Automist Smartscan should be connected to the non-protected side of the consumer unit.
Page 49 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.
Page 51: Maintenance
CAUTION! Do not attempt to repair the Automist Smartscan wall head or pump unit. Doing so will invalidate your warranty. Automist Smartscan should be serviced or replaced if any part of the system, including any heat alarms, has been exposed to fire conditions.
Page 53 Pump damaged in alarm condition by pressing STOP on the pump. transit If Automist Smartscan is not triggered, power off the system and replace the relay with a two-way a.c. light switch. The NO and NC terminals on the switch will normally be labelled L1 and L2 (both L1 and L2 terminals must be present and connected).
Page 54: Warranty
If the product is found to have failed for reasons outside our warranty cover Plumis may quote to repair the unit and return it. Where products are replaced or repaired under warranty, they will be returned to a UK address free of charge.
