Verify approval status for the specific system configuration

Approval and certification status must be evaluated against the specific container size, working pressure, component set, arrangement, system configuration, jurisdiction, and scope of the applicable certification record.

Governing principle

Approval status is configuration-specific

Configuration-specific approval

Approval and certification status varies by system configuration, including container size, working pressure, component, arrangement, and jurisdiction. Approval of one configuration does not automatically extend to another.

A product-family reference, component approval, prior project acceptance, or approval in another jurisdiction does not by itself establish approval of the proposed installed system.

The applicable certification record, listing scope, limitations, model information, and project requirements must be reviewed before an approval claim is used.

Configuration review

What a configuration review compares

Suppression-agent system family
Container size
Container working pressure
Valve and actuation arrangement
Releasing and control components
Discharge nozzles
Pipe and fitting limitations
Manifold or multi-container arrangement
Component combinations
System operating sequence
Applicable design concentration
Hazard and occupancy
Installation jurisdiction
Certification-record scope
Model and part-number alignment
Stated limitations and conditions
Current document revision
Approval verification requires comparison of the proposed configuration against the current applicable certification record and controlled technical documentation.
Approval claims

Approval claims must be specific

Any approval or certification statement used in a quotation, specification, drawing, submittal, proposal, website, or installation record should identify the system configuration and the applicable scope of the certification record accurately.

Certification organization
Product or system category
Applicable model or configuration
Working pressure
Container size or range
Listed components and arrangements
Limitations and conditions
Current certificate or directory status
Jurisdictional applicability
General statements such as “UL approved,” “FM approved,” “fully certified,” or “approved system” must not be used without confirming that the statement accurately applies to the specific configuration and context.
Component vs system

Component status does not automatically establish system status

A listed, approved, recognized, or certified component does not automatically establish approval of the complete suppression system or of every arrangement in which the component may be used.

Components must be used within the combinations, ratings, limitations, and installation conditions defined by the applicable system documentation and certification record.

Jurisdiction

Jurisdictional acceptance remains project-specific

Approval or certification status does not replace review of the adopted codes, project specifications, local requirements, permit conditions, and Authority Having Jurisdiction expectations applicable to the installation.

Final project acceptance remains subject to the specific system configuration, submitted documentation, installation, inspection, testing, and AHJ review.

Current records

Current records must be verified before use

Certification records, directory information, controlled manuals, component data, limitations, and model information may be revised. The current applicable records must be reviewed before preparing or relying on an approval statement.

Superseded, preliminary, translated, extracted, reformatted, or third-party copies must not be treated as controlling unless DueNorth has expressly identified them as current and approved for use.

Public availability

Not every approval record is necessarily public

Public website content may summarize approval considerations or provide released records, but it may not include every certification document, limitation, correspondence item, or configuration detail needed for project verification.

Contact DueNorth when the proposed configuration or approval status cannot be confirmed from the current public information.
