This product is a WIFI smart photoelectric smoke detector, designed with low-power MCU. It is an early warning device that cannot sense gas, heat, or flame, and cannot prevent the occurrence of fires or extinguish fires.
It can monitor and detect the presence of smoke in real time, and can detect visible particles (smoldering fires) faster than ionization smoke detectors.
Once smoke and fire danger is detected, the detector's red LED indicator light will always be on and an alarm will sound to remind you and your family in time. Smoke detectors should be installed in all guest rooms, living rooms, storage areas, basements, etc. in the home where a fire could occur.
