Automist Smartscan Hydra Operation
When triggered by a Plumis multi-sensor wireless alarm or a wired detector, all the linked spray heads
will begin scanning. They start measuring the temperatures within the room using an infrared (IR
thermopile) sensor. The scan is looking for an exceptionally high temperature reading, or a differential
increase between scans. Once the temperature exceeds a threshold that head is deemed to have
successfully located a fire. All heads which locate a fire during a scan are then compared to see which
has the best view.
The selected spray head will lock onto the selected location, and activate the high-pressure pump,
driving mains water through the unique nozzle unit, quickly directing a dense fog into the location of
the fire. The high momentum vertical spray orientation with a horizontal trajectory is designed so even
shielded fires can be saturated with a turbulent flow of mist, suppressing the fire.
Watermist has a different principle of firefighting to traditional sprinklers which suppress fires by wetting
surfaces and directly cooling the flames with large water drops. Water mist uses fine droplets, that
evaporate at the base of the fire, to extract heat and displace the oxygen fuel. This results in fire control,
suppression, or extinguishment. Our spray heads are wall mounted (around light switch height) to avoid
ineffective evaporation in the hot layer in the ceiling and the upward flow of hot combustion products.
Automist leverages the natural turbulence the fire creates and seeks to ensure watermist is entrained in the
fire plume.
Automist is a member of the International Water Mist Association’s (IWMA) and of its “Archimedes Club” for
the products which utilise the principle of buoyancy to improve the performance of water-based fire-
fighting system. Archimedes principle states that the upward buoyant force exerted on a body immersed in
a fluid (i.e. liquid or gas), whether fully or partially submerged, is equal to the weight of the fluid that the
body displaces and acts in the upward direction at the centre of mass of the displaced fluid.

Introduction to Design
The Automist design brief must originate from the Client, the Architect, their Main Contractor, or their
appointed Fire Engineer as they are the only participants with the knowledge required of the building and
occupancy risks, and the overall Fire Safety Plan and the role that the Automist system plays in assuring
safety: this responsibility should not be devolved to the Automist Installer.
Specification of the requirements of any residential and domestic active fire suppression system (AFSS) is
not a trivial matter. Although standards and guidance provide design solutions for some basic situations,
any situation where occupancy, circumstance, or building challenges warrant special consideration, the
user is directed to seek the services of a risk expert. It is the responsibility of the Client, or their appointed
representative, to consider these, and communicate the results of their deliberations to the Automist
designer / installer so that these can be accounted for within the design.
Use and Specification of Automist Smartscan Hydra
Automist Smartscan Hydra is intended to be used as an alternative to domestic/residential fire sprinklers or
water mist system as it has been shown to have equivalent or better fire performance when installed as per
these guidelines. Where guidance or fire engineering principles indicate that suppression must be deployed
in a particular part or parts of a property, Automist Smartscan Hydra must be installed to protect exactly
the same areas, whether the purpose is to compensate for means of escape problems or to extend the
available time for firefighters to arrive. Installation and design can only be carried out by trained and
Authorized Automist Installers.
As per Registered Detail EWS534:
The system is limited in use to those specific situations identified in Table 2 of BS 9991; 2015 'Fire Safety in the
design, management and use of residential buildings - code of practice'.
The system must be designed, installed and maintained by a Plumis accredited Installer in accordance with BS
8458: 2015 Fixed Fire Protection Systems - Residential and Domestic Watermist Systems - Code of Practice for
Design and Installation and in accordance with the most up to date Plumis Automist Smartscan Hydra Design,
Installation, Operation and Maintenance (DIOM) Manual.
Design limits are detailed in BS 8458 2015. These include the limits of application based on fire tests identified in
Table 3 of BS 8458 2015 'Fixed Fire Protection Systems - Residential and Domestic Watermist Systems - Code of
Practice for Design and Installation'. A comprehensive fire engineering assessment would be needed to justify
installations where these limits are exceeded.
For more information on using Automist Smartscan Hydra to meet building regulations –view APPENDIX A.
The system can also be used as an elective fire safety upgrade for enhancing an otherwise code compliant
dwelling. In these situations, certain design guidelines can be relaxed depending on the objective (e.g.
covering only the hob area when a client wants to use the system to reduce the risk of cooking fires in an
otherwise code compliant property) but this objective must be strategy must be documented by the client
and confirmed by Plumis in writing or supported by a fire engineering justification.

Room Compatibility
Summary
A single Automist Smartscan Hydra spray head kit can protect an area within a 6m radius from the spray
head location. The spray head must therefore have approximate line of sight of any possible fire hazards
within this range. The spray head must be positioned at least:
•1.5m away from any hob
•1m away from any oven (if in direct line of sight)
•3m away from any log burners or small fireplaces
Visibility extends radially from each mist head and ends wherever there is an obstruction. The default
radius is 90 degrees as shown below, to mitigate the potential of obstructions 1.5m either side of the spray
head. Annual commissioning includes a verification that the system is not being obstructed inadvertently.
Customers are made aware of the need not to block the view of the spray head through a warning,
engraved on the face plate.
Figure 3: A spray head with a default 90 degree line of sight spray pattern
Note: this is not a complete layout –additional spray heads would be required to complete the scheme.
If an obstruction is equal or more than 1.2m high, it must be regarded as blocking the line of sight from any
spray head positioned within 3m and reflected in the layout drawing. For example, bookshelves, wardrobes,
large fridges, or vertical radiator covers with actual dimensions. Obstructions higher than 1.5m and wider
than 0.3m must be regarded as blocking the line of sight at any distance. This does not relate to a
householder deciding to disable the suppression system; full obstruction of the spray head or the creation
of de facto room partitions with bookcases are akin to wilfully removing fire doors, decorating over
sprinkler heads or removing detectors and are beyond the scope of this recommendation.
The overall objective of a layout plan is to ensure the coverage pattern covers all the square footage within
the property. The allowable shadow area (unprotected space) is:
•1.1 m2per room
•2.8 m2per dwelling unit (property)
Automist Smartscan Hydra supports up to 6 spray heads per pump and controller pair. If in doubt it is
always advisable to add another head to your scheme.

IMPORTANT! Do not install Automist Smartscan Hydra outside Plumis guidelines. Installing Automist
Smartscan Hydra outside these guidelines without confirmation in writing from Plumis could make you
responsible for deaths or injuries. A layout specification tool is available on the Plumis Partner Site
(https://plumis.co.uk/partner.html) to help designers meet the Plumis guidelines and follow the Automist
Smartscan Hydra specification rules. The layout tool is for design guidance only and does not absolve the
designer from full responsibility for all system designs they create and any deviations from the Company’s
installation guidelines.
As per BS8458 doorways and staircases should be excluded from coverage, provided that the layout of the
property is such that the doorway or staircase is likely to remain in use i.e. will not be blocked by a
combustible object. Additionally, the designer may wish to picture a doormat having the width of the door
or staircase and 0.8m in the other dimension, at the foot and head of every staircase and on both sides of
every doorway. Combustible obstructions will not routinely be placed in these zones as they would render a
portion of the property inaccessible.

Preferred Positions
When a spray head is in a preferred position, the coverage pattern can be increased by 45 degrees on the
effected side because the location mitigates the introduction of obstructions.
1) Head placement near an internal corner (away from the centre of open walls)
Rationale:
This rule stops the installer from placing the head too close to the internal corner where it could be
obstructed along the perpendicular wall. It also aims to prevent the head from being located too
far away from the internal corner so a large item can be placed in between the spray head and the
corner.
Methodology:
Between 0.5 –1.5m from an internal corner
Figure 4: Too close to the perpendicular wall,
the coverage can be hindered by placement of
a large item against that wall
Figure 5: Between 0.5m and 1.5m away from
the perpendicular wall we allow a full spray
pattern on the side closest to the wall ✔
2) Head placement near an external corner (away from the centre of open walls)
Rationale:
This rule stops the installer from placing the head too far away from the external corner (<1m). Any
further and the occupant might put something between the edge of the corner and the spray
head.
Methodology:
Up to 1m away from the edge of an external corner
Figure 6: Close to the external corner (<1m)
we allow a full spray pattern on the side
closest to the wall ✔
Figure 7: Too far away from the external
corner (>1m) , the coverage can be hindered
by placement of a large item in between.

SMARTSCAN
®
3) Head placement near a door (away from the centre of open walls)
Rationale:
This rule uses the heads proximity to the door opening to prevent obstructions being placed
alongside it. It also prevents the head from being too far away from the door hinge (0.8 -1.5m) and
is considerate of which way the door swings.
Methodology:
Between 0.8 -1.5m from the door hinge
IMPORTANT! If the head is placed on the side closest to the hinge a door self-closer must be fitted!
Figure 8: Close to the door hinge (0.8-1.5m) we
allow a full spray pattern on the side closest to
the opening ✔
Figure 9: Close to the door hinge (0.8-1.5m)
we allow a full spray pattern on the side
closest to the opening when a door closer is
fitted ✔
4) Head placement near a door in a corner (away from the centre of open walls)
Rationale:
When mounting the head in a corner on a wall perpendicular to a door, this rule uses the heads
proximity to the doors footprint to prevent an obstruction being placed in between. It also
prevents the head from being too far away from the door’s footprint (>1m).
Methodology:
Up to 1m from the door’s footprint when in a corner
Figure 10: Close to the door’s footprint (Up to
1m) we allow a full spray pattern on the side
closest to the door ✔
Figure 11: Too far away from the door’s
footprint (>1m) we don’t allow a full spray
pattern on the side closest to the door ✔

®
5) Head placement near a window (away from the centre of open walls)
Rationale:
This rule uses the heads proximity to the window to prevent obstructions being placed alongside it.
It also prevents the spray head from being too far away from the window (>1m) and is considerate
of curtains.
Methodology:
Up to 1m from the edge of a window.
At least 0.5m from the edge of the window curtain.
Figure 12: Close to the window opening (<1m)
we allow a full spray pattern on the side
closest to the opening. At least 0.5m from the
edge of the window curtain if present ✔
Figure 13: Too far away from the window
(>1m), the coverage can be hindered by
placement of a large item in between
6) Above a worktop (away from the centre of open walls)
Rationale:
This rule assumes good visibility above a worktop and stops the installer from placing the head too
close to the edge of the worktop (>1.5m). Large white goods are often positioned along worktop
edges. This is overruled by an internal corner when rules overlap.
Methodology:
Up to 1.5m away from the edge of worktop.
Overruled by a corner when rules overlap.
Figure 14: An 180 degree spray pattern can be
assumed when above a worktop and more
than 1.5m from the edge ✔

®
7) Built within a cupboard, bookshelf, or joinery (away from the centre of open walls)
Rationale:
This rule assumes good visibility when the spray head is built into the external face of a cupboard,
bookshelf, or joinery unit. The design of the unit is as such it would be unusual to put furniture in
front of it.
Figure 16: An 180 degree spray pattern can be
assumed when the spray head is built into the external
face of a bookshelf or joinery unit ✔
Figure 17: Example of a build into the
external face of a bookshelf or joinery
unit ✔
8) Built into a trunking or a nib/fireplace (away from the centre of open walls)
Rationale:
This rule assumes good visibility when the spray head is built into the middle of a vertical trunk or
a nib.
Methodology:
The nib must be at least 0.45m deep and 0.25 –2m wide. Otherwise the angle is reduced.
Figure 18: An 180 degree spray pattern can be
assumed when the spray head is built into the
external face of a nib that is at least 0.45 deep

9) Between a worktop and a perpendicular wall (away from the centre of open walls)
Rationale:
This rule assumes good visibility for a sprayhead on a perpendicular wall from a worktop and
prevents the installer from placing the head too far away from the edge of the worktop (>1.5m).
Methodology:
Up to 1.5m away from the edge of worktop when near to a corner.

worktop (>1.5m), and the coverage can be
hindered by placement of a large item
between the sprayhead and the worktop
10) Two spray heads in the middle of an open wall
Rationale:
This rule assumes good visibility between two spray heads when they are placed less than (<3m)
apart.
Methodology:
Up to 3m between two sprayheads on the same wall.
Figure 22: An extra 45 degree spray pattern
can be assumed when the sprayheads are less
than 3m apart on the same parallel wall ✔

is 155 mm (height) by 42 mm (depth) by 155 mm (width).
•Ceiling heights are limited to 3.5m following the guidance on BS 8458:2015. Higher ceiling applications
of up to 5m are possible if there is no fire loading above 3m but require a written justification from a
fire engineer, increased ceiling height increases detector activation time.
•The controller should be positioned near or next to the consumer unit, or if not possible next to the
pump, if the pump is located in an area that is: a) in a separate compartment from the protected
volume b) not within a basement.
•A 3/4” water supply (connection) with a WRAS approved isolation valve located inside the cupboard and
positioned so that the connection point will not be obstructed when the pump is installed.
•A cold-water supply at the inlet of the system which can deliver 8 litres per minute flow at a minimum
of 1.5 bar (150kPa) and a maximum of 16 bar (1.6 MPa) static pressure. In case that pressure or flow is
too low, a priority valve or a booster pump must be used to provide the required flow and pressure.
(Note: the water filter is qualified to maximum 6 bar. Therefore, the PRV (pre-set to 3 bar,
maximum 16 bar input) must be installed upstream of water filter as shown in Figure 2). It is
responsibility of the installer to ensure the water supply to the Automist pumps is adequate. An outside
pipe diameter of less than 28mm is a good indicator that a survey is required.
•A dedicated electrical supply circuit in fire resisting cabling such as FP200. This must be on a C-type
breaker, on a RCBO or an RCD protected circuit. The MCB+RCD circuit (C type) or RCBO (C type) circuit
must protect only the Automist Smartscan Hydra system and not be incorporated with any other circuit
in the property or have any spare ways for future circuits.
•Metal consumer units complying with 18th Edition IET Wiring Regulations to BS 7671 2018; do not
require the addition of an over box to meet BS476 Part 22 (1987) and EN1364 (1999).
•IMPORTANT! If power cable can encounter parts having a temperature rise exceeding 50°C, the wiring
insulation must be protected, for example, by insulating sleeving having an appropriate temperature
rating i.e. near boiler or hot water pipes. Operating ambient temperature is above 4°C. Do not install
Plumis equipment in location which are likely to drop below this minimum temperature requirement.
•IMPORTANT! The maximum allowable data cable length in the system is 80m (from the controller to
the pump to the furthest head). It includes the maximum allowable data cable from pump to the
controller of 30m plus the maximum data cable length to the furthest head from the pump of 60m.
