Automist Smartscan Hydra Operation
When triggered by an Apollo multi-sensor wireless detector 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
domestic 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
are saturated with a turbulent flow of mist, suppressing the fire.
Automist Smartscan Hydra can be stopped manually by pressing a button on the controller’s front panel.
Water mist has a different principle of firefighting to sprinklers which suppress fires by wetting surfaces and
directly cooling the flames with large water drops, helped by gravity. Water mist uses fine droplets that evaporate
at the base of the fire to extract heat (cool) the fire and displaces oxygen from the fire zone, resulting in fire
control, suppression or extinguishment. Thus, water mist works best when placed closer to the ground avoiding
ineffective evaporation in the hot layer in the ceiling and the upward flow of hot combustion products. Automist
leverages this phenomenon by placing the spray head halfway up the wall (around light switch height): between
the hot layer and furniture. This allows increased fire suppression performance with the same amount of water.
Automist is a member of the International Water Mist Association’s (IWMA) “Archimedes Club” for the products
which utilize the optimum deployment of water mist technology.

Automist Smartscan Compliance and Fire Performance
Automist Smartscan Hydra was independently tested by Exova Warringtonfire and was able to demonstrate full
compliance with the fire performance criteria of the BS 8458:2015. In short, Automist Smartscan Hydra is
performance compliant with BS 8458:2015 despite not being fully prescriptively compliant, which is the essence
of innovations: a smarter approach to reach the same end goal: suppression performance.
The full report "BS 8458: 2015: Method for Measuring the Capability of a Watermist System to Control a Fire -
"Room Fire Test for Watermist Systems with Automatic Nozzles" Document Reference 396489" can be
downloaded from the Plumis website.
For more details on the descriptive and performance requirements of the International Building and Fire codes
please see Roadmap for compliance in Appendix A.
Household and similar electrical appliances –Safety: Smartscan System
Clarifications
•The Smartscan system is a Class I appliance, meaning the system provides additional electric
shock protection in the form of a fully earthed pump enclosure
•The Automist pump and controller unit is a stationary device
•The Smartscan head is a fixed appliance
•The Automist pump unit uses a power supply cord compliant with National electrical codes and
must meet UL Standards 62 and 817. –if the cord is damaged, it must be replaced by Plumis to
avoid a hazard
Plumis’ Quality Assurance
Concept

HOW TO SPECIFY SMARTSCAN

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 fire performance. Where guidance or fire engineering
principles indicate that suppression should be deployed in a particular part or parts of a property, Automist
Smartscan Hydra should be installed to protect exactly the same areas, whether the purpose is to compensate for
means of egress problems or to extend the available time for firefighters to arrive. Installation and can only be
carried out by trained and Authorized Automist Installers.
Room Compatibility
Summary
A single Automist Smartscan Hydra spray head kit can protect an area within a 19.7 ft (6m) radius from the spray
head location. The spray head should therefore have approximate line of sight of any possible fire hazards within
this range. The spray head must be positioned at least:
•4.9 ft (1.5m) away from any kitchen stove/range
•9.8 ft (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 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 2: 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 more than 3.9 ft (1.2m) high, it should be regarded as blocking the line of sight from any spray
head positioned within 9.8 ft (3m). Obstructions higher than 4.9 ft (1.5m) and wider than 0.9 ft (0.3m) should be
regarded as blocking the line of sight at any distance. This does not relate to a homeowner 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 or removing smoke detectors and are beyond the scope of this
recommendation.
