Cylinder Style FM200 Fire Detection Tube System

FM200 fire detection tube system is a fire-fighting device for detecting fire and extinguishing fire, It has a red color tube small tube which is used for detect fire and suppress fire automatically, this device is made up of storage cylinders, detection tube, signal feedback device, it use HFC-227ea or CO2 as extinguishing agent, can be used for some special places, like some narrow spaces where not be able to install piping systems and not be able to install fire alarms.

It is a fire extinguishing system which is low in cost, simple in structure and reliable in performance.

It has two mode, one is direct mode, which use the red tube as fire detection and fire suppression medium together; another is indirect type, which use the red tube as fire detection medium, but use a 8mm copper pipe as fire suppression medium.

WORKING PRINCIPLE

Direct type: this kind of device connect with storage cylinder by way of ball valve and container head valve, and installed in the protection zone, the end terminal of the fire detection tube has a pressure gauge, which is used to show the pressure in the fire detection tube; When a fire occurs, the fire detection tube is heated, Fractured at the melting point of the fire detection tube, extinguishing agent is sprayed from the cracked hole to the source of the fire to suppress fire.

Indirect type: It detects fire by the fire detection tube, and control the opening and closing of the bottle head valve, and then suppress fire by the copper pipe and its nozzle to release HFC-227ea agent; the fire detection tube is connect with ball valve and container head valve, the releasing tube is connect with the outlet of the container head valve, when fire occurs, the fire detection tube will be heated, and the container vale is open to start the device, the fire extinguishing agent is spraying out from the copper pipe, to put out fire.

Fire detection tube system is also installed as per the design in format of .dwg or .pdf, just like piping FM200 systems and aerosol systems, it is a complete system with pressure switch, fire alarms etc.

Fire detection tube system is mainly be installed in electrical cabinet and control panels.
