DueNorth provides controlled technical documentation, configuration-specific approval information, and project-support resources for qualified suppression-system review, coordination, submittal preparation, installation, inspection, and maintenance.
System selection, design, installation, commissioning, inspection, maintenance, and service must follow the current controlled documentation applicable to the specific system configuration and project.
Superseded, preliminary, translated, extracted, reformatted, or third-party copies must not be treated as the controlling technical record unless DueNorth has expressly identified them as current and approved for use.
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. The applicable certification record, listing scope, model information, limitations, and project requirements must be reviewed before an approval claim is used in a specification, drawing, submittal, quotation, or installation.
Technical submittal support depends on the project scope, hazard, enclosure, occupancy, system configuration, equipment selection, piping arrangement, operating sequence, applicable standards, approval requirements, and Authority Having Jurisdiction expectations.
Hydraulic-calculation software is controlled and is not provided as a public download.
Access, authorization, training, version control, approved system data, and permitted use must be coordinated directly with DueNorth where applicable.
Calculations must use the approved method, current software version, applicable component data, and configuration limits associated with the system being designed.
Verify the part number, version, date, and release status before relying on any technical document.
Website content is provided for general product and application orientation. It does not replace the current controlled manual, approved calculation method, project drawings, specifications, applicable standards, certification records, qualified system design, installation requirements, or AHJ review.
Final suitability, design, installation, commissioning, inspection, maintenance, and acceptance depend on the specific project and system configuration.
