Description
The Smoke Detector Alarm is a device designed to detect smoke and alert people to potential danger. It features a white color, excellent stability, high sensitivity, and a low battery indicator. The alarm can be easily tested with a test button and is designed for quick installation. It uses a photoelectric detector with infrared diodes to detect smoke, and has a special chamber to shield external light while still allowing smoke to enter. When smoke density reaches a certain level, an alarm signal is emitted. The device also has a special structure and ASIC to protect against dust, moths, and outside light interference. It is suitable for use in various environments such as houses, shops, hotels, restaurants, offices, schools, banks, libraries, and warehouses. The Smoke Detector Alarm operates on a 9V battery (not included) and has a transmission frequency of 433MHz. It has a working current of lower than 40mA and a standby current of lower than 10uA. The material used is ABS and the working frequency is 433MHz. The alarm emits a sound of more than 75dB and has a transmission distance of 100-150m in an open area.
