Choose a system through a project review, rather than a product name alone. Begin with the hazard, enclosure and the approval pathway at the destination.
Compare the inputs that matter
| System family | Questions for the project review |
|---|---|
| Water mist | Water supply, nozzle arrangement, hydraulic design and hazard-specific evidence |
| FM200 / HFC-227ea | Enclosure, agent quantity, discharge arrangement and destination requirements |
| FK-5-1-12 | Selected equipment format, agent documentation and model-specific approvals |
Ask for evidence for the proposed configuration
Review current product documentation and confirm the equipment scope. A company management-system certificate does not establish approval of a particular system design.
This guide supports procurement discussions. Final design and approval require qualified project professionals and the applicable local requirements.
