The Embedded FK-5-1-12 Fire Suppression Device is a highly integrated fire protection product specifically designed for equipment interiors and localized enclosed spaces. The device uses FK-5-1-12 clean agent as the extinguishing medium and is installed in an embedded configuration directly adjacent to fire hazard sources, enabling early-stage fire suppression and rapid extinguishment.
Based on the protection philosophy of “suppression first, extinguishment second,” the device discharges FK-5-1-12 at the incipient stage of a fire to effectively reduce combustion intensity and prevent fire growth and escalation. It is particularly suitable for applications with stringent requirements for continuous equipment operation, safety, and space efficiency, and is recognized in international markets as an equipment-level, localized fire protection solution.
The device is directly embedded within the protected equipment or structure, positioned near high-risk ignition points to achieve faster and more precise fire suppression and extinguishment.
FK-5-1-12 is discharged at the early stage of fire development, suppressing the combustion reaction and effectively preventing small fires from developing into major incidents.
The unit features a compact form factor and can be flexibly installed inside equipment without affecting original structure or normal operation.
FK-5-1-12 leaves no residue, is electrically nonconductive, and noncorrosive. No post-discharge cleanup is required, making it ideal for protecting sensitive and precision equipment.
Prefabricated and modular design minimizes on-site work, reduces maintenance effort, and offers clear life-cycle cost advantages.
The device remains in a normal monitoring and standby condition, embedded within the protected equipment.
When a fire occurs inside the equipment and elevated temperature is detected, the actuation component is activated.
The internal actuation mechanism operates rapidly, releasing the FK-5-1-12 extinguishing agent into the protected space.
The agent vaporizes rapidly, absorbing heat and interrupting the combustion chain reaction.
The fire is effectively suppressed or extinguished, preventing further fire development.
