The indirect fire detection tube extinguishing device is an automatic fire suppression unit that integrates early-stage fire detection with controlled extinguishing agent discharge. The system employs highly sensitive fire detection tubes as linear heat-sensitive detection elements. When a fire breaks out in the protected area and generates abnormal high temperature, the fire detection tube ruptures rapidly, which acts as an activation signal to trigger the opening of the extinguishing agent cylinder valve. The extinguishing medium is then uniformly discharged throughout the entire protected area via nozzles or piping networks.
Unlike direct-type systems, the indirect fire detection tube extinguishing device releases the extinguishing agent through nozzles. It is more suitable for application scenarios requiring total flooding protection, relatively enclosed spaces, or areas where fires may occur at multiple points. As a reliable solution, it is widely used in the international market for equipment - level and small-space total flooding protection.
The system employs CO2 (Carbon Dioxide) as the extinguishing agent. The CO₂ fire extinguishing system has been widely recognized internationally and is particularly suitable for suppressing fires involving flammable liquids, flammable gases, and energized electrical equipment.
Integration of Early - Stage Detection and Total Flooding Suppression
The fire detection tubes are responsible for rapid heat - sensitive detection, while the nozzles undertake uniform discharge, achieving effective coverage of the entire protected space.
Power - Free, Independent and Reliable System
The system operates entirely based on mechanical and pressure principles, without relying on external power supplies or control panels, making it suitable for locations with high reliability requirements.
Controllable Discharge of Extinguishing Medium
The discharge direction and coverage area are controlled via nozzle design, avoiding local under - coverage or protection blind spots.
High Adaptability and Flexible Installation
The routing of fire detection tubes and the quantity of nozzles can be flexibly configured according to the size and structure of the protected space, adapting to various complex environments.
Easy Maintenance and Low Life - Cycle Cost
Featuring a mature structure and fewer components, the system requires minimal daily inspection and maintenance workload, resulting in low long - term operational costs.
Under the normal operating condition of the system, the fire detection tubes are routed along the ceiling or at high - risk locations of the protected space, and the fire extinguishing agent is stored in pressurized containers.
When a fire occurs, the local high temperature causes the fire detection tube to rupture at the location first exposed to heat.
The pressure inside the fire detection tube is rapidly relieved, which triggers the actuation of the actuation valve.
The fire extinguishing agent is uniformly discharged to the protected area through the piping and nozzles, providing rapid suppression and extinguishment of the fire source.
