Aspirating smoke detector (ASD) is divided into two-tube and four-tube types, both of which are based on dual fusion detection technology of smoke concentration and particle counting, showing higher sensitivity. It can trigger alarm in the early stage of fire as well as can achieve online monitoring and evaluation of the fires based on the characteristic gases generated by fire.

The automatic condensed aerosol fire extinguishing device operates on the chemical suppression principle, interrupting the combustion chain reaction. The fire extinguishing agent reacts with free radicals in the chain reaction, thereby halting the propagation of combustion. This prevents the self-sustaining combustion process and effectively suppresses the fire.

The cabinet-type Novec 1230 fire extinguishing equipment utilizes Novec 1230 (chemical name: Fluoroketone FK-5-1-12) as the extinguishing agent, designed for self-contained total flooding applications. A single protected area is safeguarded by one or multiple cabinet-type fire extinguishing units.

The spot-type temperature and smoke detectors in various places are usually in a long-term unmaintained state, with their function status remained unknown, posing significant safety risks. For testing as per the methods in national standards, disassembly is required, which is not only inefficient and costly but also carries the risk of secondary damage. By simulating the alarm conditions of smoke and temperature detectors, this device can achieve rapid and accurate quantitative calibration, which is also portable by a single person with simple operation and high efficiency.
