Planning for Data Center Fire Suppression

　　Gas fire suppression systems are a common type of fire protection system, and thanks to their outstanding performance, they are used in many settings—such as server rooms housing sensitive equipment, libraries, electrical distribution rooms, and archive storage areas—among other critical locations.

　　Gas fire suppression systems are essential safety equipment for various instrument and equipment rooms. It is crucial to select gas-based automatic fire-extinguishing devices that are non-corrosive and leave no residue. These gas-based systems deliver excellent fire suppression performance while protecting electronic equipment from damage. Additionally, in pipeline-type gas fire suppression systems, the nozzles are strategically placed at the top of the protected area, ensuring they do not compromise the overall aesthetic or functionality of the equipment room.

　　Data Center Fire Suppression System Planning

　　1. Given the unique characteristics of the machine room, a gas-based fire suppression system has been selected. Additionally, other auxiliary electrical equipment required by the gas fire suppression system has been planned accordingly.

　　2. Install a gas emergency stop button.

　　3. Install two audible and visual alarms, and place a gas discharge indicator light—one inside and one outside the fire suppression area.

　　4. Install one gas discharge indicator light, which is controlled by the fire control panel receiving the feedback signal after the pressure switch on the gas pipeline activates. Other equipment in the alarm system, such as manual call points and fire alarms, should be installed according to fire safety standards.

　　Data Center Fire Extinguisher

　　1. Choose a gas fire suppression system.

　　2. Determine the size and orientation of the cylinder room based on the data center's area.

　　3. Able to ensure the extinguishing agent in the cylinder is evenly sprayed throughout the fire suppression area.

　　4. The area of the cylinder room can be slightly smaller. Another important consideration in the design is the load-bearing capacity of the cylinder room. Typically, building floors can support between 600 kg/m², with some structures capable of handling up to 1000 kg/m². However, when selecting high-capacity fire extinguishing cylinders, it’s essential that the floor slab can bear a load of at least 1000 kg/m². Therefore, during the planning of the fire suppression system, it’s crucial to clearly specify both the weight and footprint of the cylinders, enabling structural engineers to determine whether reinforcement of the cylinder room is necessary during the structural design phase—ensuring the overall safety of the building.

　　Protection requirements for the data center fire suppression area

　　1. Pass through the air conditioning ducts in the fire zone, activating the electric fire dampers on both sides of the equipment.

　　2. Regarding the air-conditioning system with ductless underfloor supply, an electric fire damper is installed below the walls in the fire suppression zone. Normally open, the fire damper ensures adequate airflow for air conditioning in the equipment room, but closes completely during a fire to prevent the extinguishing agent from leaking outside the protected area.

　　3. Doors installed in the fire suppression system area must all open outward and be equipped with door closers.
