Optical Smoke Detection: The smoke detector uses advanced optical sensing technology to detect smoke, minimize false alarms, and ensure accurate and timely notifications in the event of a fire. High Alarm Volume: The alarm emits a powerful sound of ≥85dB (at a distance of 3 meters), ensuring that you and your loved ones are immediately alerted in the event of an emergency. Dual Alarm Mechanism: The smoke detector combines both audible and visually visible warnings, increasing the chances of a quick response in noisy environments or for people with hearing impairments. Low Power Consumption: Operates with a static current of ≤10µA to save energy during normal operation, while the alarm current remains below ≤120mA during activation. Test and Silence Button: With conveniently placed buttons for easy testing of the device and to silence false alarms, which provides user-friendly functionality. Indicator Lights: The LED indicator conveys the smoke detector's operating status, including low battery and fault warnings. Low Voltage/Fault Detection: Integrated function to detect low battery voltage and system faults, ensuring the continuous reliability of the device. Widely used in various environments: The fire alarm is suitable for use in temperatures from -10°C to 55°C, with a relative humidity limit of ≤95%.   Specifications: Color: White Size: 10.2x3.9 cm Material: ABS Power supply: CR123A 3V 10-year lithium battery Indicator Light: It can indicate various working status of the detector and supports low voltage/fault detection. The battery does not need to be replaced during the life cycle. Standby time: 10 years Detection type: Photoelectric fire alarm (to prevent false alarms) Alarm volume: ≥85dB (3 meters directly in front) Alarm mode: Sound and light alarm simultaneously Working current: Static ≤10µA Alarm current: ≤120mA Buttons: Test and mute buttons A
