【Advanced photoelectric sensor technology】Photoelectric type smoke detectors are more sensitive to ignition than ionic type smoke detectors, good at detecting slow combustion (like upholstery or electrical fires), lower false alarm rate, and have a longer service life. 【Sensitivity 0.1 Bar & Sensor detection speed 0.08 Seconds】This smoke alarm is equipped with a high-sensitivity error correction chip and is designed to provide accurate monitoring information, rapid response, and avoid false alarms or false triggers. It also features low power consumption and long standby time. 【LED flashing & 85dB alarm】When the smoke alarm is triggered, the red LED light will immediately flash rapidly and emit an alarm of ≥85dB. With strong penetration, it can wake you up even if you are fast asleep in another room, allowing you to detect a fire as quickly as possible. 【Easy installation & low battery warning】The smoke alarm measures 4.2 x 4.2 x 0.66 inches and can be quickly installed on any ceiling or wall using 3M adhesive tape or screws (included in the set). The smoke alarm is powered by a 9V replaceable battery. When the battery is low, a low battery alarm is triggered to remind users to replace the battery. 【Trusted Safety & Peace of Mind】Rigorously tested to meet UL 217 safety standards. Features an End-of-Life signal and is designed with durable, high-quality components for dependable protection year after year. If you encounter any other issues, please contact us.
