Fire Detection Tube
Explore Jianan fire detection tube suppression systems for electrical cabinets, machinery, and equipment enclosures, with direct and indirect release options.
Automatic Protection for Enclosed Equipment Hazards
Jianan Fire Protection Technology supplies fire detection tube suppression systems for electrical cabinets, machinery, engine compartments, and other small equipment enclosures.
When exposed to sufficient heat or flame, the pressurized detection tube ruptures near the fire and activates the system.
Direct systems release agent through the tube, while indirect systems trigger a separate valve, pipe, and nozzle network; basic pneumatic operation does not require external power.

Fire Detection Tube System Features
- Automatic Pneumatic Detection: The pressurized tube detects heat and activates the system without external power for the basic release function.
- Direct and Indirect Release: Direct systems discharge through the ruptured tube, while indirect systems release agent through separate piping and nozzles.
- Close-to-Hazard Detection: Flexible tubing can be routed near likely ignition points inside compact cabinets and machinery enclosures.
- Multiple Agent Options: Compatible systems may use clean agents, CO₂, or dry chemical according to the hazard, cleanup tolerance, occupancy, and system design.
- Compact Equipment Protection: The cylinder, valve, detection tube, and release components provide self-contained protection for small, defined hazards.
- Alarm and Shutdown Interfaces: Pressure switches can provide discharge signals, remote alarms, power shutdown, ventilation shutdown, or fuel isolation.
- Operation During Power Loss: Pneumatic detection and release can remain functional during an electrical outage, although monitoring and auxiliary controls may require power.
- Product-Specific Coverage: Protected volume, tube length, agent quantity, piping, nozzle arrangement, and temperature limits depend on the selected product.
- Tube Routing and Maintenance: Detection tubing must be protected from abrasion, sharp bends, vibration, chemicals, excessive heat, and mechanical damage.

Applications
Typical fire detection tube suppression applications include:
- Electrical control cabinets
- Switchgear and distribution panels
- CNC machines and machine tools
- Industrial automation equipment
- Generator and engine compartments
- Hydraulic power units
- Printing and processing machinery
- Telecommunications cabinets
- UPS and power-control enclosures
- Vehicle and mobile-equipment compartments
- Other small enclosed equipment hazards
These systems are intended mainly for small, defined hazards where the tube can be routed close to likely ignition points.
They should not be assumed suitable for complete rooms, open industrial areas, multiple separated cabinets, lithium-ion battery thermal runaway, or transportation applications without product-specific testing.

Frequently Asked Questions
Find quick answers about product selection, installation, compliance, and customization.
What is a fire detection tube suppression system?
It is a compact automatic system that uses a pressurized heat-sensitive tube to detect fire and activate the extinguishing-agent discharge.
What is the difference between direct and indirect systems?
A direct system releases agent through the point where the tube ruptures. An indirect system uses tube pressure loss to open a valve and discharge agent through separate nozzles.
Does a fire detection tube system require electricity?
Basic pneumatic detection and release do not require external power. Alarms, monitoring, pressure switches, and shutdown interfaces may still require electricity.
Which extinguishing agent should I choose?
Clean agents suit sensitive electronics, CO₂ suits selected unoccupied hazards, and dry chemical provides rapid knockdown but leaves residue. The choice depends on the fuel, enclosure, occupancy, cleanup requirements, and system compatibility.
How much space can one system protect?
There is no universal protection volume. Capacity depends on agent quantity, enclosure leakage, ventilation, tube routing, discharge method, nozzle arrangement, and product limits.
