When sprinklers cost more than gas suppression.
By the time a sprinkler activates, your data is already underwater. Clean-agent gas floods the room before the damage starts, and leaves your equipment exactly as it was.
Cross-zoned detection, double-knock confirm, pre-alarm, full discharge, inside the SANS 14520 window.
Clean agents evaporate. Servers, switchgear and archives stay running through and after a discharge.
Every C4 install handed over with a signed compliance certificate, room integrity test and asset register.
Four clean-agent gas suppression systems.
Gas suppression floods a sealed room with a clean agent that puts a fire out in about ten seconds without water or residue, so servers, switchgear and archives keep running. C4 installs four agents, FM-200, Novec 1230, Inergen and CO₂, and specifies the one that matches your room volume, equipment and occupancy, all designed and certified to SANS 14520.
Every agent has a job it does best. We don’t pick a favourite. We pick the right gas suppression agent for your room, your equipment and your risk profile. Tap any agent below for the full technical detail.
Choosing a gas suppression agent depends on room volume, occupancy and what is being protected, and C4 Fire & Security confirms the choice during a free SANS 14520 site assessment. FM-200 (HFC-227ea) and Novec 1230 (FK-5-1-12) are clean agents that flood a sealed room in under ten seconds, leave no residue and let equipment keep running, which makes them the usual choice for server rooms, data centres and switchgear. Inergen (IG-541) is a breathable inert blend of nitrogen, argon and carbon dioxide that protects life as well as assets, so it suits archives, museums and occupied control rooms. High-pressure CO₂ is reserved strictly for unoccupied industrial enclosures such as generator rooms and paint stores, because its extinguishing concentration is dangerous to people. Every system is designed, installed and certified to SANS 14520 with a door-fan integrity test, and integrates with the commercial fire detection and alarm installation that triggers the discharge.
C4 designs and installs every system to SANS 14520 with the agent-specific concentrations and integrity tests required for sign-off. We explain each option during the site assessment and recommend the agent and concentration that matches your room, your equipment, and your risk profile.
Three things every C4 install includes.
Designed
Hydraulic calcs, agent concentration, nozzle layout, cylinder sizing, detection zoning and control panel logic, all to SANS 14520. Stamped drawings issued with every project.
Installed
Cylinders, distribution pipework, discharge nozzles, detection, abort stations and the suppression panel, fitted by accredited engineers, not subcontractors.
Certified
SANS 14520 compliance certificate, door-fan room integrity test, asset register and a maintenance schedule. Re-issued at every annual service.
A five-step install you barely notice.
Most C4 gas suppression installs run between two and six weeks from site walk-through to handover, depending on room size and out-of-hours scheduling.

Engineers on the ground, not on a plane.
C4 is based at The Simondium Guild on the R45 between Klapmuts and Franschhoek. That puts our engineers within an hour of every major Western Cape industrial node, and on emergency callout 24 hours a day.
C4 Fire & Security designs, installs and certifies clean-agent gas suppression systems for server rooms, data centres, switchgear and archives across Cape Town and the Western Cape, working to SANS 14520, the standard for gaseous fire-extinguishing systems. From its base at The Simondium Guild on the R45 between Klapmuts and Franschhoek, C4 covers Cape Town, the Northern Suburbs, Stellenbosch, Paarl, Somerset West and the West Coast with 24/7 emergency callouts. Each installation includes a SANS 14520 hydraulic design and agent-concentration calculation, cylinder sizing, nozzle layout, cross-zoned detection, a door-fan room-integrity test on commissioning and a compliance certificate at handover. C4 installs four agents, FM-200, Novec 1230, Inergen and CO₂, and specifies the one that matches the room, the equipment and whether staff may be present, rather than fitting a single default. The team brings over 30 years of combined fire-engineering experience and SAQCC Level 5 qualifications.

Years combined experience
Our engineers have specified, installed and signed off gas suppression systems across Western Cape data centres, factories and wine estates for over three decades.
SAQCC Level 5 qualified
The highest fire-safety qualification recognised in South Africa. Required for sign-off on commercial and industrial suppression systems.
Emergency response
Suppression systems don’t fail at 09:00 on a Tuesday. Our 24/7 line covers fault, false-discharge and re-fill across the Cape.
Full-scope, in-house
Design, installation, servicing, refills and room-integrity testing, handled end to end by one C4 team rather than subcontracted out.
Frequently asked questions.
How much does a gas suppression system cost?
Pricing depends on room volume, agent choice and integration with existing detection. A 50 m³ server room typically falls between R180,000 and R450,000 turnkey, certified to SANS 14520. We quote precisely after a free site assessment.
Is a gas suppression system safe for people in the room?
Inergen and Novec 1230 are designed for occupied spaces and remain safe at design concentration. FM-200 allows safe egress within the prescribed window. CO₂ is restricted to unoccupied industrial enclosures only. We never specify it where staff work.
How often must a gas suppression system be serviced?
Annual service plus a five-yearly cylinder hydrostatic test under SANS 14520. C4 schedules the visits, runs door-fan integrity testing, and re-issues a compliance certificate after every annual service.
Will a gas suppression system damage electronics?
No. Clean agents (FM-200, Novec 1230, Inergen) leave zero residue and do not conduct electricity. Servers and switchgear continue running through and after a discharge with no clean-up required.
Can C4 retrofit gas suppression into an existing room?
Yes. We routinely retrofit data centres, switchrooms and archives. The site assessment covers room sealing, abort stations, ventilation interlocks and integration with your existing fire panel. A door-fan integrity test confirms the room can hold the agent.
What happens if the system discharges accidentally?
A double-knock detection sequence and abort station mean accidental discharge is rare. If it does happen, clean agents leave no residue. The room ventilates and operations continue. C4’s 24/7 emergency line covers re-fill and re-certification.
Which gas suppression agent is best for a server room or data centre?
For most server rooms and data centres in South Africa we specify Novec 1230 or FM-200: both are clean agents that suppress fire in seconds, leave zero residue and let equipment keep running. Inergen suits larger occupied spaces, and CO² is reserved for unoccupied industrial enclosures. The right choice depends on room volume, occupancy and ventilation, which C4 confirms during a free SANS 14520 site assessment.
Is gas suppression better than sprinklers for protecting electronics?
For rooms full of electronics, gas suppression is usually the safer investment. A sprinkler discharge stops the fire but soaks servers, switchgear and archives, often causing more loss than the fire itself. Clean-agent gas suppression floods the room in roughly ten seconds, extinguishes the fire and leaves no water or residue, so operations continue. C4 designs both and gives an honest verdict on which your space actually needs.
A gas suppression system for a commercial server room in South Africa typically falls between R180 000 and R450 000 turnkey, certified to SANS 14520, though C4 Fire & Security quotes precisely only after a free site assessment that measures room volume and confirms the agent. SANS 14520 systems require an annual service plus a five-yearly cylinder hydrostatic test; C4 schedules the visits, runs the door-fan room-integrity test that confirms the room can hold the agent for its design hold time, refills and recharges cylinders after any discharge, and re-issues the compliance certificate after every annual service. Because clean agents such as FM-200, Novec 1230 and Inergen leave no residue and do not conduct electricity, equipment keeps running through and after a discharge, avoiding the water damage a sprinkler discharge causes to servers, switchgear and archives. C4 designs both gas and water systems and gives an honest verdict on which a space actually needs.
