Orbis Fire Suppression

Frequently Asked Questions

General Company & Product FAQs

What is a fire suppression system?

A fire suppression system is an automatic or manual system designed to detect and extinguish fires without relying on water. These systems use clean agents, gases, or dry chemicals to suppress fire by removing heat, oxygen, or interrupting the combustion process. They are commonly used where water could damage equipment or is ineffective.

What is the difference between fire suppression and fire sprinklers?

Fire suppression systems extinguish fires using agents such as clean gas or powder, while sprinklers rely on water. Suppression systems act faster, cause no water damage, and are suitable for electrical and mechanical enclosures where sprinklers are impractical.

Micro / Cabinet-Level Suppression

What is a micro fire suppression system?

A micro fire suppression system is a compact, pre-engineered system designed to protect enclosed spaces such as electrical cabinets, control panels, battery enclosures, and machinery housings. These systems detect fires at the source and discharge directly inside the enclosure, stopping fire spread before it escalates.

Where are micro fire suppression systems typically used?

They are commonly installed in electrical panels, MCCs, server racks, CNC machines, wind turbines, solar inverters, telecom cabinets, battery energy storage systems (BESS), and marine equipment enclosures.

DLP vs ILP

What is the difference between DLP and ILP fire suppression systems?

DLP (Direct Low Pressure) systems discharge the agent directly through a heat-sensitive detection tube that ruptures at the fire source. ILP (Indirect Low Pressure) systems use detection tubing, smoke detection, or manual activation to open a valve and discharge agent through dedicated nozzles. DLP systems are simpler and power-free; ILP systems offer greater coverage flexibility and control options.

Which is better: DLP or ILP?

Neither is universally better. It depends on the application. DLP systems are ideal for small, sealed enclosures and remote installations. ILP systems are better suited for larger cabinets, divided enclosures, or applications requiring nozzles, manual release, or panel integration.

Agents & Safety

What fire suppression agents do you use?

Our systems support clean agents such as FK-5-1-12 (Novec-type), HFC-227ea (FM-200), CO₂, and ABC dry powder. Agent selection depends on enclosure size, fire risk, environmental conditions, and regulatory requirements.

Is FK-5-1-12 safe for electronics?

Yes. FK-5-1-12 is electrically non-conductive, leaves no residue, and does not damage sensitive electronics. It suppresses fire by absorbing heat rather than displacing oxygen, making it ideal for electrical and electronic equipment.

Installation & Maintenance

Do fire suppression systems require power?

DLP systems require no external power and operate entirely mechanically. ILP systems can operate without power or integrate with control panels, solenoids, and detection devices depending on configuration.

How often do fire suppression systems need maintenance?

Visual inspections are typically performed monthly, with functional checks every six months. Cylinders require hydrostatic testing at intervals defined by DOT or CE regulations, usually every five years.

Compliance & Approvals

Are your fire suppression systems compliant with international standards?

Yes. Our systems are designed in accordance with standards such as NFPA 2001, ISO 14520, UL, CE, TPED, and DOT, depending on the product and region.

Do I need approval from the Authority Having Jurisdiction (AHJ)?

Local approval requirements vary by region and application. Many cabinet-level micro suppression systems do not require full room-level approvals but should always be reviewed with the AHJ or fire protection engineer.
