Frequently asked questions

How does an automatic electrical panel suppression system work?

The heat-sensitive polymer detection tube activates at an application-dependent threshold of approximately 100–120 °C. In a direct arrangement it opens near the fire source and discharges the agent directly; in an indirect arrangement the pressure drop triggers the valve and nozzles discharge into the panel enclosure.

What is the difference between direct and indirect systems?

In a direct system the detection tube is also the discharge path and directs the agent to the point where the fire starts. In an indirect system the tube detects the fire; the valve opens after the pressure drop and separate nozzles distribute the agent inside the panel.

Where is it used?

Typical applications include electrical distribution and compensation panels, server and UPS cabinets, data centres, CNC and automation panels, GSM/telecom cabinets, generator and turbine control units, and sensitive equipment enclosures.

How is an FM200 electrical panel suppression system selected?

This product family uses FM200 (HFC-227ea). Cylinder capacity is selected by considering equipment, fire risk, protected volume, openings and ventilation together. The final configuration is confirmed in the quotation and technical design.

How are maintenance and pressure checks performed?

The gauge, safety valve, polymer detection tube and body coating are checked. Refill and leak-tightness checks are recorded, and a qualified team should perform these inspections at least once a year.

What is the device working pressure?

Özkartay records specify an 18 bar working pressure. The pressure and suitability of the selected model should be confirmed in the quotation and technical documentation before application.

INSIDE THE PANEL SYSTEM

The red tube follows the detection route.

The cylinder, pneumatic valve and heat-sensitive tube work together. Explore the components and their arrangement inside a cabinet. The images represent a direct-discharge layout; the application depends on the selected system and project.

Cylinder outside, detection tube inside — representative direct system.

Why does the tube follow the equipment rows?

The detection tube is routed near the equipment being protected. Broad bends help avoid crushing the tube, while clips keep it in place. The cylinder can be mounted inside or outside the cabinet in an orientation permitted by the system.

Representative internal mounting. Position and orientation depend on the selected system’s requirements.

How does it work?

  1. Heat is detected

    The pressurised heat-sensitive tube ruptures at the fire’s hot spot.

  2. Pressure change triggers the valve

    A drop in tube pressure activates the pneumatic release arrangement.

  3. Agent is discharged

    The extinguishing agent follows the discharge path of the direct or indirect system.

Direct discharge

The same tube detects heat and carries agent to the rupture point. These illustrations do not include a separate discharge nozzle.

Indirect discharge

The detection tube triggers the valve; agent is distributed through a separate discharge line and nozzles. Components are selected for the particular system design.

Cylinder and retaining bracket

The cylinder stores the extinguishing agent. Retaining straps and a backplate secure it to the selected mounting surface.

Why this shape or arrangement?
The cylindrical vessel provides pressurised storage; retaining straps limit movement of the cylinder.
What matters when selecting the component?
A model-permitted orientation, adequate support and access to the valve and gauge.
Representative close view of a pneumatic valve, small pressure gauge and red detection tube connection on a cylinder neck.

Representative component illustration

Pneumatic valve and gauge

The valve controls agent release from the cylinder. The gauge monitors the pressure circuit to which it is connected; the arrangement is model-dependent.

Why this shape or arrangement?
Connecting the detection tube to the valve lets a pressure change reach the release mechanism.
What matters when selecting the component?
Compatible connections, leak-tight seals and the correct gauge. Alarm or power isolation can require additional equipment.

Representative component illustration

Heat-sensitive detection tube

This is a tube rather than an electrical wire. In a pneumatic system it is pressurised and ruptures at a point exposed to fire heat, triggering the system.

Why this shape or arrangement?
Its flexibility lets it follow different equipment rows. The route is selected around the identified risk points.
What matters when selecting the component?
Uncrushed bends, secure clips and protection at sharp-edged openings.

Fittings, clips and end-of-line closure

Fittings connect the tube to the valve and its termination. A closed end-of-line fitting allows the detection circuit to remain pressurised.

Why this shape or arrangement?
Clips retain the route; a protected opening reduces rubbing against a metal edge. The end of the detection circuit is closed.
What matters when selecting the component?
System-compatible fittings and tubing, leak-tight joints and access for servicing.

Design and installation guide

1 kg FM200 (HFC-227ea) automatic electrical panel suppression system: selection and application guide

This 1 kg FM200 (HFC-227ea) option is assessed for local suppression inside an electrical cabinet or suitable enclosed equipment. Cylinder capacity alone does not define the protected cabinet volume; agent quantity, openings and the chosen discharge arrangement are assessed together.

An automatic electrical panel suppression system for electrical panels, server and UPS cabinets, data centres and industrial automation equipment. It is considered for enclosed spaces with heat and electrical-arc risks, using polymer detection tubing for direct or indirect early-stage fire suppression. System selection, extinguishing agent and protected volume are confirmed from the project risk assessment.

01

Selection, placement and maintenance

Selection considers the product function, the protected risk and operating conditions together. These steps support the site survey and quotation.

  1. Cabinet and hazard data

    Record cabinet dimensions, equipment layout, cable penetrations and fire load during the survey. A shared cylinder for separate cabinets is assessed only within a design supported by the selected system.

  2. Agent quantity and openings

    Determine FM200 quantity from the protected volume and required design conditions. Assess fans, vents and door openings for agent loss during discharge.

  3. Detection and discharge arrangement

    Select a direct or indirect arrangement through compatibility of the detection tube, valve and any separate nozzle line. Route detection around hazard points and include alarm and power coordination in the project.

  4. Commissioning and operating records

    Check installation, connections and the release scenario against manufacturer instructions. Include cylinder charge, detection tubing and alarm connections in maintenance, with service verification before restoring a discharged system.

02

Applications and site planning

These examples show why placement and equipment requirements can differ between facilities using the same product.

Production-line electrical cabinets

Site requirement
Cable density, fans and covers opened during maintenance.
Application approach
Define protection by cabinet and include cover and fan states in the suppression scenario.

Control and automation enclosures

Site requirement
Sensitivity to downtime and separate internal compartments.
Application approach
Plan detection and discharge around the compartments. Assess the relationship between cabinet protection and room-level detection and suppression separately.
