This smoke detector features an integrated design combining a flame-retardant ABS housing with a photoelectric sensing module:

**Main Housing:** Constructed from white, flame-retardant ABS plastic; resistant to high temperatures and corrosion, and compliant with fire safety product standards.

**Core Module:** Features a photoelectric smoke sensor capable of accurately detecting fire-related smoke while maintaining a low false alarm rate.

**Operation & Indicators:** Includes a central "TEST" button for one-touch self-testing, as well as an LED status indicator that provides real-time feedback on the device's operational status.

**Audible Alarm:** Equipped with a bottom-mounted buzzer aperture that emits a high-decibel alarm sound (exceeding 85 dB) in the event of a fire.
