The extremely early fire warning device adopts dual fusion detection technology of smoke concentration and particle counting, which has higher sensitivity and can achieve alarm in the early stage of fire. At the same time, it combines the characteristic gases at the time of fire occurrence to achieve online monitoring and evaluation of fire.

The hot aerosol automatic fire extinguishing device adopts the principle of chemical suppression fire extinguishing to block the chain reaction. Fire extinguishing agents react with free radicals in a chain reaction, interrupting the chain reaction of combustion and preventing it from continuing, thus playing a role in suppressing fires.

Cabinet style perfluorohexane fire extinguishing device, using perfluorohexane as the extinguishing medium, is suitable for unit independent total flooding fire extinguishing systems, and is protected by one or several sets of cabinet style fire extinguishing devices to protect a protective area.

Point type temperature and smoke fire detectors used in various places are usually in a long-term state of no maintenance, and the functionality of the equipment is unknown, posing significant safety risks; If the testing is carried out according to the methods in national standards, it needs to be disassembled, which not only has low efficiency and high cost, but also poses a risk of secondary damage. This device can simulate alarm conditions such as smoke and temperature sensors, achieve fast and accurate quantitative verification, be carried by a single person, be easy to operate, and have high efficiency.
