This S-type aerosol fire extinguishing device features an integrated design comprising a fully enclosed, cylindrical carbon steel housing and a built-in aerosol generating agent:

**Main Housing:** Features a thickened, red-painted carbon steel shell that is rust-proof, corrosion-resistant, and impact-resistant, making it ideally suited for industrial environments such as utility tunnels and power distribution rooms.

**Core Components:** Contains a built-in S-type thermal aerosol generating agent, an initiator, and a cooling assembly; during activation, a chemical reaction generates a clean aerosol extinguishing agent to suppress the fire.

**Electrical Interface:** Equipped with a top-mounted terminal box that supports two triggering modes: automatic activation (linked to a fire alarm system) and manual activation.

**Identification Plate:** The housing bears labels detailing technical specifications and safety warnings, clearly marking key information such as operating guidelines and expiration dates.

**Mounting Structure:** Features a dual U-shaped wall-mounting bracket at the base, allowing for direct attachment to the walls of utility tunnels or equipment rooms; this design ensures convenient installation and minimizes space requirements.

**Discharge Port Design:** Features a honeycomb-patterned, multi-perforated nozzle on the end face, ensuring the uniform and rapid discharge of the extinguishing agent to effectively cover the designated protection zone.
