Records rooms, archives, collections storage, vaults, and other spaces holding high-value or sensitive assets require project-specific evaluation of the fire hazard, stored materials, enclosure conditions, occupancy, ventilation, piping constraints, and approval requirements, with attention to secondary water damage and post-discharge cleanup.
A records, archive, or collections designation does not determine the final suppression system. Selection depends on the specific fire hazard, stored materials, storage arrangement, fuel load, enclosure characteristics, occupancy, operating sequence, storage-space limitations, piping routes, applicable standards, system configuration, approval status, and Authority Having Jurisdiction requirements.
These examples are illustrative. The final protection approach depends on the specific hazard, equipment, enclosure, occupancy, operating requirements, system configuration, and project approvals.
Paper, film, magnetic media, and other stored materials can behave differently in a fire. Densely packed or enclosed storage, such as compact mobile shelving or closed cabinets, can limit agent distribution to the fire and must be evaluated as part of the hazard review.
The DN5112 FK-5-1-12 system is intended for total-flooding protection of appropriate enclosed hazards. Deep-seated fires in densely stored materials require separate evaluation and may not be suitable for clean-agent protection. The suppression system does not replace detection, housekeeping, compartmentation, or other required safeguards.
Total-flooding protection depends on the ability of the protected room to establish and maintain the required agent concentration for the applicable design period. Doors, penetrations, environmental-control systems, pressure effects, and leakage paths must be evaluated as part of the project design.
HVAC and environmental-control shutdown, damper operation, door position, pressure-relief venting, and post-discharge ventilation must be coordinated with the system operating sequence and applicable requirements.
For records and high-value contents, secondary damage from the suppression method can be as significant as the fire itself. Suppression-system design should be coordinated with the owner’s preservation, recovery, environmental-control, inspection, maintenance, and post-discharge response requirements.
FK-5-1-12 leaves no agent residue after discharge and does not introduce water into the protected space, reducing cleanup associated with the suppression agent.
FK-5-1-12 is an engineered total-flooding clean-agent system that may be considered for records, archive, and high-value asset spaces where no suppression-agent residue, minimal cleanup associated with the suppression agent, electrically non-conductive protection, available storage space, enclosure conditions, stored materials, design criteria, and configuration-specific approval requirements support its use.
FK-5-1-12 suppresses fire primarily through chemical interference with the combustion process, combined with heat absorption.
Final suitability requires project-specific review using the current controlled system documentation.
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.
