This is a multifunctional fire alarm: - There is an emergency LED light and a tricolor flashing LED: a green LED indicates normal operation, a red LED indicates an alarm status and a yellow LED indicates a fault. There is also a built-in lithium battery with a lifespan of 10 years. Convenient check button. According to the instructions, X-SENSE recommends checking the operational status of the device by pressing the test button once a week. This prevents false alarms and is ideal for use in kitchens, stairwells or other areas where cigarette smoke or fumes may occur. 24/7 self check mode. If there is a problem, he will notify me immediately. - UL Listed and made from US Fire Department approved polycarbonate material. People must be very confident in its quality. Installation is also very easy! The alarm clock doesn't have a connected function, but it's already loud enough! It successfully replaced my old fire alarm.
