Single Zone Single Bottle FM200 Cabinet Pipe System
Reliable Gas Fire Equipment for Industrial Use
Product Overview
The FM200 Single-Zone Single-Cylinder Pipe Network Fire Suppression System is an automatic gas fire extinguishing system using HFC-227ea (FM200) as the extinguishing medium, specifically designed to protect a single protected enclosure. The system consists of one set of storage equipment protecting one fire zone, making it suitable for independent single protection areas with special requirements.
The system operates at 4.2MPa or 5.6MPa storage pressure, with single-cylinder agent capacities ranging from 40kg to 180kg. The discharge time is ≤10 seconds, enabling rapid fire suppression at the early stage. The system supports three activation modes: automatic, electrical manual, and mechanical emergency manual, ensuring reliable operation under any condition.

System Components
The FM200 single-zone single-cylinder pipe network system consists of three main parts:
1. Fire Extinguishing Equipment
| Component |
Description |
| Agent Storage Cylinder |
Stores FM200 agent; welded steel cylinder with red epoxy coating |
| Container Valve |
Controls agent release; supports pneumatic and manual operation |
| Siphon Tube |
Ensures complete agent discharge from the cylinder |
| Flexible Hose |
Connects container valve to the manifold |
| Liquid Check Valve |
Prevents agent backflow from manifold to cylinder |
| Manifold |
Collects agent from multiple cylinders |
| Safety Relief Valve |
Automatic overpressure protection |
| Discharge Nozzle |
Distributes agent evenly into the protected area |
2. Pipe Network
- High-pressure galvanised steel pipes
- Flanges, elbows, tees, reducers
- Transports agent from cylinder room to protected area
3. Electrical Controls
- Fire detectors and gas fire control panel
- Audible and visual alarms, alarm bells
- Manual start/stop buttons
- Discharge indicator lights
- Signal feedback device
Working Principle
The system uses total flooding fire suppression. The working principle is as follows:
Step 1: Fire Detection
- Smoke detectors and fixed-temperature heat detectors continuously monitor the protected area
- When a single detector sends a fire signal, the control panel activates audible/visual alarms without starting the extinguishing system
Step 2: Double Confirmation
- When both detectors simultaneously send fire signals, the system enters a delay state
- Indoor and outdoor alarms are activated, and linked equipment (dampers, HVAC) is closed
Step 3: Personnel Evacuation (Delay Phase)
- Delay time is adjustable from 0 to 30 seconds
- Personnel can safely evacuate during this period
- "Emergency Stop" button can cancel activation during the delay
Step 4: Agent Discharge
- After the delay, the control panel outputs DC24V to activate the solenoid valve
- The solenoid valve releases high-pressure nitrogen from the drive cylinder
- Nitrogen opens the container valves on the agent cylinders via the start-up pipeline
- Agent flows through flexible hoses, manifold, and pipe network to the nozzles
Step 5: Total Flooding Fire Suppression
- Agent fills the entire protected area within 10 seconds
- Extinguishing concentration (8%~10%) is rapidly established
- Fire is suppressed effectively
About FM200 Extinguishing Agent
FM200 (HFC-227ea) is a clean agent that extinguishes fire primarily through chemical inhibition, supplemented by physical cooling effects.
Key Properties:
- Colourless, odourless, low toxicity, non-conductive
- Does not contaminate protected objects; no damage to precision equipment
- Low extinguishing concentration; reliable suppression of Class B, C, and electrical fires
- Compact storage; high critical temperature; liquefied storage at room temperature
Environmental Properties:
- Zero Ozone Depletion Potential (ODP) - no damage to the ozone layer
- Atmospheric lifetime of approximately 31~42 years; superior to halogenated agents
- NOAEL value of 9% - safe for occupied spaces
Applications
The FM200 single-zone single-cylinder system is suitable for a wide range of protected enclosures:

Key Advantages
1. Dedicated Single-Zone Protection
Designed specifically for single protected areas with precise agent quantity calculation - no agent waste and simple system configuration.
2. Fast Response - Effective Fire Suppression
Discharge time ≤10 seconds, rapidly establishing extinguishing concentration at the early fire stage to control fire spread and minimise damage.
3. Multiple Activation Methods - Reliable Operation
Automatic: Dual-detector confirmation triggers automatic agent release
Electrical Manual: Emergency push button manual activation
Mechanical Emergency: Direct manual operation of container valves
4. Clean Agent - No Secondary Damage
FM200 is non-conductive, non-corrosive, and leaves no residue. No post-discharge cleanup is required, enabling rapid business recovery.
5. Total Flooding - No Blind Spots
The pipe network and nozzles distribute agent evenly throughout the protected area, ensuring complete coverage with no protection gaps.
Activation Modes Detail
Automatic Mode
With control selector in the "Automatic" position:
- Single detector alarm: audible/visual alarm only - no activation
- Dual detectors alarm: 30-second delay → linked equipment shutdown → agent release
- "Emergency Stop" can cancel activation during the delay
Electrical Manual Mode
With control selector in the "Manual" position:
- Detector alarm triggers audible/visual alarm only - no activation
- Personnel confirm fire, then press "Emergency Start" to activate
- Alarm signal continues until reset
Mechanical Emergency Mode
For situations where the control panel is completely inoperative:
- Manually close linked equipment and cut power
- Open the selector valve (if present)
- Manually open container valves one by one or in groups to release agent

Maintenance and Servicing
Routine Maintenance
- Monthly: Visual inspection - no impact deformation, no rust, coating intact, safety pins and seals in place
- Annually: Check storage pressure; if gauge is not in the green zone, weigh the cylinder to verify agent quantity
- Every 5 Years: Full system inspection - disassemble, clean, reassemble, and re-test all components
Post-Discharge Restoration
After the system has been discharged, a qualified service provider must perform:
- Replace the solenoid actuator sealing diaphragm

Frequently Asked Questions
Q: What is the difference between single-zone and combined distribution systems?
A: A single-zone system uses one set of storage equipment to protect one protected area. A combined distribution system uses one set of storage equipment to protect multiple areas via selector valves, with agent quantity calculated based on the largest protected zone (maximum 8 zones per system).
Q: What is the maximum protection range of a single zone?
A: Maximum protection area is 800m², and maximum protection volume is 3,600m³ per zone.
Q: What is the agent discharge time?
A: Discharge time is ≤10 seconds, ensuring rapid extinguishing concentration build-up at the early stage of a fire.
Q: What power supply is required for the system?
A: The solenoid valve requires DC24V/1.5A. The control panel requires AC220V main power with DC24V backup power.
Q: How can I check for agent leakage?
A: The pressure gauge provides an initial indication - the reading should be in the green zone. Annual weighing provides accurate leakage data. If leakage exceeds 5% of the filling quantity, refill or replace.
