Fire Suppression Systems
FM-200 and Novec 1230 Clean Agent Suppression in Bangladesh
A clean agent system floods a closed room with a gas that puts out fire without water, residue or damage to electronics. FM-200 (HFC-227ea) and Novec 1230 (FK-5-1-12) are the two common agents. Both are safe for occupied rooms at design concentration, which makes them the usual choice for server rooms, control rooms and archives.

FM-200 or Novec 1230: what is the real difference?
FM-200 is the trade name for HFC-227ea, a hydrofluorocarbon. It has a long track record and a compact cylinder footprint, but as an HFC it has a high global warming potential and falls under the HFC phase-down agreed in the Kigali Amendment to the Montreal Protocol. Supply and cost may change over the life of the system.
Novec 1230 is the 3M trade name for FK-5-1-12, a fluoroketone stored as a liquid that vaporizes on discharge. Its global warming potential is very low and it breaks down in the atmosphere within days. 3M has exited PFAS manufacturing, so FK-5-1-12 is now supplied by other manufacturers under their own names. We specify the agent, not the brand.
Why does the room have to be tested before handover?
A clean agent works by holding a set concentration in the room long enough for the fire to go out and not reignite. If the room leaks through cable holes, false-ceiling gaps or poorly fitted doors, the gas escapes and the hold time is lost. A system can be correctly sized and still fail because of the room.
So we run a door fan integrity test, as described in NFPA 2001, which pressurizes the room and measures leakage. The result predicts the hold time. If it falls short, we find and seal the leaks with firestop materials and test again. This is far cheaper than a test discharge, which wastes the agent.
How does the system decide to release?
Most systems use two detection zones, so one faulty detector cannot cause a discharge. The first alarm warns the room. The second confirms the fire, shuts down air handling and starts a countdown with sounders and strobes, giving people time to leave or press abort. Then the cylinders release, normally within ten seconds.
Manual release stations let someone fire the system if they see a fire before the detectors do, and an abort switch holds the countdown if the alarm is false. The panel also reports to the main fire alarm, so the building knows a release is under way and the fire team does not open the room too early.
How it’s done
How we deliver it, step by step.
- 01
Room assessment
We measure the volume, note equipment, openings and ventilation, and check whether people work there.
- 02
Agent design
We choose the agent, calculate quantity and concentration, and place cylinders and nozzles.
- 03
Install and seal
Our team installs pipework, cylinders, detection and the release panel, and seals penetrations.
- 04
Integrity test
A door fan test measures room leakage and confirms the predicted hold time.
- 05
Commission
We simulate the release sequence end to end, with no agent discharged, and record each step.
Price guide
What sets the price.
Every site is different, so we price from a survey, not a rate card. These are the factors that move the number, and the written quote shows each one.
- Protected room volume, including floor void and ceiling
- Agent choice: HFC-227ea or FK-5-1-12
- Number of cylinders and pipe network length
- Detection type and release panel specification
- Sealing work needed to pass the integrity test
- Interfaces with HVAC, dampers and the building alarm

Frequently asked questions
FM-200 is not banned for fire protection as far as we know, but HFCs are being phased down under the Kigali Amendment, which Bangladesh has ratified. That can affect long-term supply and refill cost. If you are building a new room today, we will explain both agents so you can decide with this in mind.
Yes. The agent itself, FK-5-1-12, is made by other manufacturers and sold under their own names, and listed systems use it. When we quote, we name the agent and the listed system it is approved for, so refills and future service are not tied to one discontinued brand.
Yes. Both HFC-227ea and FK-5-1-12 are designed for normally occupied spaces when used at the concentrations NFPA 2001 permits. The system still includes a pre-discharge warning and abort switch, because leaving the room during a fire is always safer than staying in it.
The main drivers are room volume, including the raised floor and ceiling void, the agent, the number of cylinders, detection and panel specification, and any sealing needed to pass the integrity test. A small server room and a full data hall differ widely, so we price from a survey.
