Marketing Claims, Technical Comparisons & Disclaimers
The information published on automist.us is intended to explain Automist technology, its potential benefits, and how it compares with conventional residential fire sprinkler systems.
Performance comparisons, water consumption figures, cost estimates and other claims are based on published research, product specifications, representative design assumptions, and documented project experience. Actual results depend on the fire scenario, building configuration, installation, water supply, maintenance and applicable regulations.
The following notes explain the basis and limitations of specific claims made across this website.
- Approximately 90% less water
The claim that Automist uses approximately 90% less water refers to a comparison of system discharge rates under representative operating conditions. Automist has a nominal operating demand of 2.37 gallons per minute (GPM). A representative residential sprinkler design using two heads, each discharging 12–13 GPM, has a combined discharge rate of approximately 24–26 GPM.
On that basis, Automist uses approximately 90% less water per minute than the two-head sprinkler comparison. Actual water consumption depends on the number of sprinklers operating, discharge pressure, system configuration and duration of operation. A single operating sprinkler, or a sprinkler system designed with different hydraulic requirements, will produce a different percentage reduction. The comparison relates to water discharge, not a guaranteed reduction in property damage.
- Up to 14× faster activation
The claim that Automist can activate 2–14 times faster than conventional concealed residential sprinklers is based on published experimental research comparing electronically controlled water mist systems with concealed sprinkler heads. In the reported experiments, concealed sprinkler activation times were approximately 2.0–13.7 times those of the electronically controlled water mist system, depending on the fire scenario and experimental conditions. These findings do not mean Automist will activate faster in every fire. Actual activation depends on factors including fire growth rate, fire location, ventilation, detector response, sprinkler characteristics and room geometry.
- Water meter upgrades, tanks and infrastructure requirements
Statements that Automist can avoid water meter upgrades, dedicated fire service connections, storage tanks or additional infrastructure refer to installations where the existing domestic water supply meets the system’s hydraulic requirements.
Automist’s low water demand can substantially reduce the infrastructure needed compared with higher-flow residential sprinkler systems. However, suitability must be confirmed through project-specific design, assessment of available water pressure and flow, and applicable plumbing and fire protection requirements. Additional equipment, modifications or approvals may be necessary. No particular installation is guaranteed to avoid a meter upgrade, tank, pump or other infrastructure work.
- Representative residential sprinkler demand: 26 GPM
The reference to 26 GPM is an illustrative residential sprinkler design calculation:
13 GPM per sprinkler × 2 hydraulically demanding sprinklers = 26 GPM.
This is a representative comparison, not a universal NFPA 13D minimum requirement.
Actual sprinkler design demand depends on the applicable standard, sprinkler listing, required design area, number of operating sprinklers, coverage, spacing, ceiling configuration, available pressure and other hydraulic design considerations.
Some compliant residential sprinkler installations may require substantially less or more than 26 GPM.
- Automist operating water demand: 2.37 GPM
The quoted Automist water demand of 2.37 GPM (approximately 9 litres per minute), sometimes rounded to 2.4 GPM, refers to the nominal operating demand of the specified Automist system.
Actual installation requirements, including minimum available water supply, are determined by the applicable product listing, hydraulic design and manufacturer’s Design, Installation, Operation and Maintenance Manual (DIOM).
The required available supply may include additional design allowances. This figure should not be treated as the sole criterion for determining water supply adequacy.
- Installation costs and potential savings
Published installation costs, sprinkler quotations, water meter upgrade fees, service lateral costs and potential savings are indicative estimates or examples rather than guaranteed prices.
Actual expenditure varies according to property location, building size, construction type, installation complexity, labour rates, utility policies, permit fees, water supply availability and contractor pricing.
Automist may reduce overall installed costs in projects where conventional fire sprinklers would require significant infrastructure upgrades. In other projects, traditional sprinklers may be less expensive.
A project-specific quotation is required to establish actual comparative costs.
- UL Listing, codes and regulatory approval
Automist is UL Listed under UL 2167A for targeted water mist fire protection in one- and two-family dwellings, within the scope and conditions of its listing.
Automist systems are designed and installed in accordance with NFPA 750 and the manufacturer’s listed installation instructions.
Automist is not an NFPA 13D sprinkler system. Its suitability as an alternative to an NFPA 13D installation depends on the applicable building and fire codes, the proposed use, and acceptance by the local Authority Having Jurisdiction (AHJ).
UL Listing does not establish automatic approval for every project or jurisdiction. Approvals granted for individual installations do not guarantee approval elsewhere.
Project-specific acceptance must be confirmed before relying on Automist to satisfy a legal fire protection requirement.
- Fire protection, water damage and insurance outcomes
Automist is designed to detect and suppress fires and to reduce the volume of water discharged compared with certain conventional sprinkler configurations.
Its performance may help reduce fire growth, water damage and consequential property losses. However, no fire suppression system can guarantee prevention of injury, loss of life, fire spread, property damage or water damage in every circumstance.
Actual outcomes depend on the nature and location of the fire, building construction, system coverage, water and power availability, system condition and other factors.
References to insurer recognition, policy eligibility, premium reductions or improved insurability describe potential or documented project-specific benefits. They do not guarantee that any insurer will accept Automist, offer coverage, reduce premiums or change policy terms.
Insurance decisions remain entirely at the discretion of the relevant insurer or underwriter.
- Artificial intelligence, thermal detection and fire testing
Automist uses electronic sensing and control algorithms to identify fire-related thermal characteristics and direct suppression towards the detected fire location.
References to artificial intelligence, machine learning, training datasets and fire testing describe technologies and development activities used in the system.
Published performance statements relate to the particular tests, algorithms, hardware and software configurations evaluated. No detection technology is capable of identifying every fire or eliminating all unintended activations.
Statements concerning the quantity of training data or tested fires refer to Plumis development records and should not be interpreted as the number of independently certified tests or real-world fire activations.
- Testimonials, case studies and demonstrations
Testimonials reflect the experiences and opinions of the individuals or organisations identified.
Case studies describe specific installations or incidents under their particular circumstances. They are not necessarily representative of all installations or guaranteed future performance. Videos, demonstrations and animations may use illustrative or controlled conditions to communicate system operation and performance. Actual installations and fire conditions may differ. - Power shower water consumption comparison
Statements comparing Automist’s water consumption with a power shower refer to its nominal discharge rate of 2.37 gallons per minute (approximately 9 litres per minute).
Actual shower flow rates vary substantially according to the equipment, operating pressure and settings. This comparison is intended to illustrate relative water discharge rates and does not establish the total volume of water consumed during a fire suppression event.
General technical and safety notice
Content on this website is provided for general information and should not replace professional fire protection design, applicable codes and standards, manufacturer instructions, or the requirements of the relevant AHJ.
Automist must be specified, installed, commissioned, inspected and maintained in accordance with its applicable listing and manufacturer’s instructions.
Technical specifications, product availability, listings, approved configurations and regulatory requirements may change. Consult the current product documentation before designing or installing a system.
These explanatory notes do not amend or replace the applicable product warranty, contractual terms or statutory rights.
Video content and visualisations
The following information applies to Automist promotional, educational and product videos, including The Moment Before, The Hidden Language of Heat and Built for What Comes Next.
Illustrative footage, visual effects and playback speed
Some video sequences use stock footage, animation, computer-generated imagery or AI-assisted visual effects to illustrate fire development, thermal behaviour and system operation.
Certain sequences may be accelerated, slowed down, edited or otherwise modified for clarity, storytelling or visual presentation. Playback speed may therefore differ from real time and should not be used to assess actual fire development, detection or suppression times.
These sequences are intended to communicate concepts and may not represent actual fire incidents, recorded temperatures or Automist system activations.
Infrared and thermal visualisations
Simulated thermal imagery illustrates how temperature differences and developing heat patterns may be represented. Colours, temperature distributions and visual effects may be illustrative rather than measurements from a thermal imaging sensor.
Actual Automist detection and response are determined by the system’s validated sensing, control and operating characteristics.
Software intelligence and detection
Animations showing multiple fire recordings, thermal profiles, pattern recognition or software decision-making are conceptual representations of the technology and its development. They do not necessarily depict the system’s actual internal processing sequence or real-time operation.
Future software capabilities
References to the continued development of Automist software describe the potential for future improvements. New capabilities, algorithms and software releases are subject to development, testing, validation and applicable certification requirements. Features and availability may vary by product version and market.
Fire protection performance
Fire suppression outcomes depend on the fire scenario, building configuration, installation conditions and system design. Demonstrations and illustrations should not be interpreted as a guarantee that any particular fire will be extinguished or that damage will be prevented.
For specific performance claims, including comparisons of water demand and activation time, refer to the relevant technical qualifications and supporting research published on this website.
