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.

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.
See the cylinder mounted inside the cabinet

How does it work?
Heat is detected
The pressurised heat-sensitive tube ruptures at the fire’s hot spot.
Pressure change triggers the valve
A drop in tube pressure activates the pneumatic release arrangement.
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.

Representative component illustration
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 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.

Representative component illustration
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
Automatic cabinet suppression: detection close to the source and local protection design
A fire developing inside an electrical or automation cabinet can affect production and connected systems. Cabinet suppression is planned to detect this local hazard and deliver the selected agent into the protected enclosure.
Özkartay’s catalog offers 1, 2, 4, 6, 12, 15 and 18 kg FM200 (HFC-227ea) automatic cabinet suppression options. Capacity is selected by considering cabinet volume, openings, ventilation and the system’s technical design limits together.
01
How is cabinet protection planned?
Cabinet protection is a local application supporting electrical maintenance and the facility’s wider fire response.
Cabinet and hazard inventory
Record enclosure dimensions, compartments, power equipment, cable loading and likely fire origins. Separated compartments are not treated as one open volume.
Volume and opening assessment
Assess fans, vents, cable penetrations and door openings. Check conditions needed for effective agent retention against the system manufacturer’s design documentation.
Direct or indirect arrangement
Design separately for direct discharge through detection tubing or indirect release in which tubing activates a valve feeding nozzles. Route tubing and position nozzles around the cabinet equipment.
Electrical and alarm interfaces
Define required alarms, monitoring and power isolation with the facility’s electrical team. Suppression does not by itself make faulty electrical equipment safe.
Installation, verification and maintenance
Check fixing, tubing and connections against the selected system instructions. Plan functional checks, handover and maintenance access; an agent discharge is not automatically assumed as part of testing.
02
Detection, discharge and integration
Define local protection limits from the selected system and actual enclosure arrangement.
Direct detection and discharge
- Operation
- Agent discharges through the opening in heat-sensitive tubing. Routing that tubing to the protected hazards is central to the design.
- Check
- Check tubing bend limits, fixing and ambient temperature against manufacturer instructions.
Indirect detection and discharge
- Operation
- An event in the detection tubing activates the valve; agent reaches the enclosure through distribution pipework and nozzles.
- Check
- Select nozzle number, positions and connections within the selected system’s permitted design arrangement.
Coordination with facility systems
- Operation
- Agree fan shutdown, alarm transmission and any required power isolation with the responsible disciplines.
- Change management
- New cables, fans, partitions or cabinets can change the protected volume; reassess the installation.
03
Applications by cabinet type
Plan local protection around enclosure layout and operating interruption requirements.
Distribution and power-factor cabinets
- Application condition
- Energised equipment, compartments and cable penetrations.
- Design focus
- Assess each compartment while retaining electrical clearances, maintenance access and alarm interfaces.
CNC and automation cabinets
- Application condition
- Production continuity, fan cooling and frequent maintenance access.
- Design focus
- Coordinate tubing or nozzles with equipment movements and assess the effect of ventilation on agent retention.
Server, UPS and telecom enclosures
- Application condition
- High airflow and differing equipment hazards.
- Design focus
- Consider cabinet and room protection together. For special risks such as battery chemistry, assess whether a clean agent alone can address the hazard.
Generator and process-control panels
- Application condition
- Vibration, temperature and critical control functions.
- Design focus
- Match mounting and ambient conditions to the selected hardware; plan commissioning and maintenance around the operating schedule.

| Design topic | Information needed | Decision |
|---|---|---|
| Agent capacity | Volume, openings and hazard | Quantity suitable for the model |
| Direct / indirect arrangement | Internal equipment layout | Tubing and nozzle routing |
| Alarm and power | Facility control sequence | Interfaces agreed with responsible teams |
| Maintenance access | Operation and cabinet access schedule | Recorded checks and change tracking |
Coordinate local cabinet protection with building detection and evacuation. Assess agent application limits and personnel safety against the selected system documentation.
Cabinet suppression depends on detection routing, enclosure conditions and operating controls as well as capacity. Establish the scope from the existing cabinet’s dimensions and layout.
