About Fire Detection Tube

Linear Pneumatic Heat Detection Tube system is a good option for small electrical, server, DNS, UPS, battery, or network rooms where you want automatic fire detection and direct suppression without complex electronic detectors.

What It Is

A heat-sensitive pneumatic tube is installed around protected equipment.
When temperature reaches a preset level (typically 68C110C depending on tube type), the tube bursts at the hottest point and triggers fire suppression.

Commonly used with:

• FM-200
• Novec 1230
• CO2 Fire Suppression System
• Dry chemical systems

How It Works

Direct Release System

1. Detection tube installed above/inside racks or panels
2. Fire heats tube
3. Tube ruptures at hottest point
4. Suppression agent discharges directly at fire source

Best for:

• Electrical cabinets
• Server racks
• Battery cabinets
• Small DNS/network rooms

---

Indirect Release System

1. Tube senses heat
2. Pressure drop activates valve
3. Entire room suppression system discharges

Best for:

• Full room protection
• Data/server rooms
• Telecom rooms

---

Advantages

• No electricity needed for detection
• Very fast localized detection
• Low maintenance
• Cost-effective for small rooms
• Works during power failure
• Easy retrofit in existing server rooms

---

Typical Installation in DNS / Server Room

Detection tube routing:

• Above server racks
• Around UPS panels
• Cable trays
• PDU panels
• Network switches

Suppression cylinders:

• Wall-mounted outside room preferred
• Connected to nozzles or direct tube release

---

Important Design Considerations

1. Choose Correct Agent

For occupied IT rooms:

• Preferred:
  • Novec 1230
  • FM-200
• Avoid total flooding CO in occupied rooms

---

2. Room Sealing

For total flooding systems:

• Door seals required
• False ceiling/floor leakage checked
• Hold time usually 10 minutes

---

3. Standards

Common standards:

• NFPA NFPA 72
• NFPA NFPA 2001
• ISO standards
• Local fire authority requirements

---

Best Use Cases

Excellent for:

• Small DNS rooms
• Telecom shelters
• UPS rooms
• Electrical panels
• ATM machines
• CNC/electrical cabinets

Less suitable for:

• Very large data centers
• Open industrial halls
• Areas with high airflow unless engineered properly

Typical Small DNS Room Solution

Example:

• 1030 m room
• Detection tube around racks
• 25 kg clean agent cylinder
• Manual release + abort switch
• Alarm integration

---

If you provide:

• Room dimensions
• Number of racks
• Ceiling height
• UPS/battery presence

I can help you with:

• Basic suppression sizing
• Tube routing layout
• Cylinder capacity estimate
• Single-line schematic
• BOQ/material list
• Typical installation drawing

Flexible and Reliable Fire Detection

The Fire Detection Tube adapts to a range of applications, from industrial enclosures to server cabinets, thanks to its customizable length and flexible design. Its instant activation and non-electric operation make it a reliable choice for environments where electrical systems may be compromised by fire or heat. With its chemical and humidity resistance, it maintains performance even in challenging conditions.


Easy Installation and Seamless Integration

Engineered for straightforward installation, the Fire Detection Tube mounts easily with clips or brackets on walls, ceilings, or inside equipment. Its compact 6 mm diameter allows for discreet integration, and with a bending radius of just 60 mm, the tube conforms to complex layouts, maximizing coverage and efficiency in fire suppression.
