FK5112 Automatic Fire Extinguisher For Control Racks/Cabinets With Smoke Detectors

Hangzhou PRI-SAFETY Fire Technology Co., Ltd. is known as one of the most professional manufacturers and suppliers of various safety products in China. If the fk5112 automatic fire extinguisher for control racks/cabinets with smoke detectors meets your requirement, welcome to buy quality equipment made in China here from our factory. Our factory will offer you one stop service and one year warranty.

Data security is important to all us. One of the most dangerous threats to our data systems is fire. The PRI-SAFETY RACK System Protects the data panel at anytime, ensures that any fire catching in the rack are dealt with quickly and effectively.

We all know how a tiny electrical flicker in a single server can sometimes spell disaster? That's exactly why we need an automatic fire system built right into the server rack itself. Think of it as a dedicated guardian for your most critical gear.

Big room-level fire systems are great for a full-blown blaze, but they're slow to react to a small fire starting deep in a rack. By the time they go off, the damage is already done. A rack-level system, on the other hand, is on the job 24/7, right where the danger is. It snuffs out a fire in its earliest seconds, often before it can even spread to the next server.

The best part is what it uses to put the fire out. Instead of water that would fry your electronics or a messy powder that ruins everything, it uses a clean, safe gas. This means your equipment survives not just the fire, but the suppression too. It's the smartest way to prevent a minor incident from turning into a major outage and a massive repair bill.

Why Does PRI-SAFETY Use the FK-5112 Agent for This Server Rack Fire System?

PRI-SAFETY specifically chose FK-5112 because its properties perfectly align with the critical needs of protecting IT equipment in a confined server rack.

FK-5112 is a type of clean agent fire suppressant. The "FK-5" designation is a classification under the ISO 14526 standard for gaseous fire-fighting agents. It is a chemical compound known as Perfluoro(2-methyl-3-pentanone).

Think of it as a sophisticated, electronically safe, and environmentally responsible replacement for older halon systems.

Using a linear temperature sensor and 2 Smoke detectors, it can detect any part inside the cabinet. Dualdetection ensures safer and more effective. The Linear detection cable activation temperature is 85°C.

Any smoke detector detect smoke, the fire system will be activated. And once the temperature reach 85°Cthe linear detection cable will activate the fire system too.At the same time the fire alarm(siren&light) start and spraying. Automatically stops after spraying.

After activation need refill the fire agent and replace the detection cable. Easy maintanence and Effective.

The Device accept 110v~240v Power, suitable for different power standard, and with the backup battery.

1. Detection Components
Linear Heat Detection Tube (LHDT):
A flexible, small-diameter (often red) tube that is routed throughout the entire protected rack, snaking past all critical equipment like servers, switches, and power supplies.

Function: This is the primary fire detector.

2. Suppression Agent & Storage
FK-5112 Agent Cylinder:
A sealed, pressurized cylinder (typically steel) that contains the liquid FK-5112 clean agent and a nitrogen propellant.

Function: This is the storage vessel for the fire suppressant. It is designed to hold the agent under pressure until the precise moment it is needed for discharge.

3. Activation & Discharge Components
Activation/Release Valve:
A mechanical valve mounted on the agent cylinder.

Function: It is connected to the Linear Heat Detection Tube. The pressure drop from the tube bursting acts as a mechanical trigger, instantly opening this valve to release the agent. This is a purely pneumatic (pressure-based) mechanism, making it very fast and reliable without needing external power.

Discharge Nozzles / Manifold:
A network of pipes and nozzles that distribute the agent.

Function: Once the valve opens, the agent flows through this manifold and is dispersed into the rack enclosure via strategically placed nozzles. These nozzles are designed to ensure the FK-5112 agent vaporizes quickly and fills the entire enclosed volume of the rack uniformly.

4. Control & Indication Components
Control Module / Panel:
The electronic "brain" of the system, usually located on the front of the 1U unit for easy access.

Function: It monitors the system's status (e.g., pressure in the detection tube, agent cylinder pressure) and provides visual and audible alerts. It typically has indicators for Normal, Fault, and Discharge conditions. It can also interface with a building's central fire alarm system.

Manual Release Button:
A prominent, usually protected, button on the control panel or at a nearby accessible location.

Function: Allows personnel to manually trigger the release of the fire suppressant if they see a fire before the automatic system activates.

5. Enclosure & Structural Components
1U Chassis:
The metal housing that contains all the above components in a standard 1U (1.75-inch tall) rack-mountable form factor.

Function: To neatly and securely integrate the entire fire suppression system into the server rack itself, making it a dedicated and self-contained safety solution.

To better ensure the safety of your goods, professional, environmentally friendly, convenient and efficient packaging services will be provided.

Designed for 1U service racks, but suitable for other servers, telecommunication and control racks/cabinets.
