Automated FK-5112 Flooding Fire Suppression System With Fire Alarm System

 

FK5112 Total Flooding Fire Suppression System is an advanced, environmentally responsible clean agent fire protection solution engineered for rapid, reliable fire extinguishment in enclosed critical spaces. Utilizing FK5112 as the extinguishing medium, the system uniformly distributes the clean agent throughout the protected enclosure to quickly suppress flames without compromising equipment safety, human occupancy, or the environment.Stored as a liquefied compressed gas, FK5112 discharges as a colorless, transparent, electrically non-conductive vapor that does not obstruct vision or interfere with evacuation. It leaves zero residue upon vaporization, eliminating post-discharge cleanup, corrosion, or damage to delicate electronics and high-value assets. The agent operates through a synergistic combination of chemical interruption and physical heat absorption, delivering fast fire knockdown for Class A, Class B, and Class C hazards.

FK5112 and FM200 clean agent fire suppression systems are designed to provide rapid and reliable fire protection for critical facilities, electrical rooms, data centers, control rooms, telecommunication facilities, archives, and other high-value assets. These systems are typically integrated with a complete fire detection and alarm network to ensure automatic fire detection and extinguishment.A standard system configuration includes smoke detectors, heat detectors, fire alarm control panels, extinguishing control units, emergency release stations, abort switches, audible and visual alarms, pressure relief devices, and other associated fire safety equipment. 

 

Working Principle of FK-5-1-12 Total Flooding Fire Suppression System

The FK-5-1-12 Total Flooding Fire Suppression System is designed to detect, suppress, and extinguish fires quickly while minimizing damage to valuable equipment and assets. The system combines advanced fire detection technology with a clean agent extinguishing system to provide fully automatic fire protection.

 

When smoke or heat detectors identify the early signs of a fire, they immediately transmit signals to the fire alarm and extinguishing control panel. After confirming the fire condition, the control panel activates audible and visual alarms to warn occupants and initiates a pre-set discharge delay, allowing personnel sufficient time to evacuate the protected area.

Once the delay period has expired, the control panel sends an electrical signal to the release actuator, opening the cylinder valve. The stored FK-5-1-12 clean agent is then discharged through a network of pipes and specially designed nozzles, rapidly flooding the entire protected enclosure with the required extinguishing concentration.

 

The FK-5-1-12 agent extinguishes the fire primarily by absorbing heat from the combustion process, reducing the flame temperature below the level required to sustain combustion. Because it suppresses fire without significantly reducing oxygen concentration, it is safe for occupied spaces when designed and installed according to applicable standards.

The system also supports manual emergency activation through a manual release station and mechanical release device, ensuring reliable operation even in the event of electrical failure. After discharge, the clean agent leaves no residue, making it ideal for protecting sensitive electronic equipment, data centers, electrical rooms, archives, museums, telecommunications facilities, and other mission-critical environments.
