The DI-M9102 intelligent light smoke detector (hereinafter referred to as the "device") can form a fire alarm system by connecting with the fire alarm system control panel (FACP). The device uses luminous indicators to visually indicate fire situations and effectively transmits alarm signals to the FACP control panel. Using innovative optical reflection technology as well as a highly advanced room design, the device is able to detect ultra-weak infrared light in a clean, natural environment. If smoke particles enter the room, the intensity of the light signal received by the scattering increases. Once the smoke density reaches a certain level, the device activates the alarm signal. To reduce interference and power consumption, the transmitting circuit operates in pulse mode, extending the life of the IR LED.

The device has a range of features, including:

• Self-Diagnosis of Errors: The ability to diagnose errors within the device.
• Magnet Test: The possibility of performing a test using magnets for verification.
• Remote indicator connections: Connectivity with remote indicators.
• Built-in microprocessor: Ability to store 14 historical data records.
• Poll Indicator Control: Option to set the polling indicator to off.
• Standard Compliance: Certified to comply with UL268.
