The fire detector device is composed of a gas cylinder, a container valve, and a fire detector tube and/or a release tube capable of releasing the fire extinguishing agent.
The fire detector is placed near or above where the source of fire is most likely to occur and is detected by a number of detection points (linear) along the fire detector. Once on fire, the fire probe tube is softened at the highest heating temperature and explodes, releasing the extinguishing medium to the protected area through the fire probe tube itself (direct system) or the nozzle (indirect system).
The main function of gas cylinders is to store high pressure fire extinguishing agents.
The fire probe tube is a new product developed in high-tech field, and it is a high-tech non-metallic composite product. It combines long-term leakage resistance, flexibility and effective temperature sensitivity, blasting, spraying extinguishing media or transmitting fire signals within a certain temperature range.
