This smoke detector operates on either AC 220V or a DC 9V battery, providing flexibility for different installation environments. With a surveillance current of less than or equal to 10µA and an alarm current of less than or equal to 12mA, it is highly efficient. The sound pressure level (SPL) exceeds 85 dB at a distance of 3 meters, ensuring the alarm is audible even in large spaces. The device is designed to work in a temperature range of -10°C to 50°C and maintains functionality in humidity levels of up to 95% RH without condensation. Additionally, if running on a low battery, it can operate for another 7 to 15 days before needing a replacement. The smoke detector is compact, with dimensions of 140 mm in diameter and 41 mm in height, making it suitable for various spaces.
