It is highly sensitive to faint smoke and slow-smoldering fires, has a low false alarm rate, and has an extended service life
【High Capacity · Low Power Consumption】This smoke alarm features a high-capacity, 3,000-mAh battery that offers three times the battery life of common 9-volt batteries on the market. Its ultra-low standby power consumption of less than 0.1 μA provides long-lasting safety protection
【Easy Installation】Simply secure the base to the wall and rotate the alarm to snap it into place. Battery-powered operation allows installation anywhere without worrying about power outages
【Honeycomb Dual-Entry Design】The 360° honeycomb smoke inlet instantly detects fires. A red LED flashes rapidly while triggering an alarm exceeding 85 decibels. Its powerful penetration will wake you even from deep sleep in the next room, ensuring danger never spreads silently
【Low Battery Alarm Function】When battery power is low, the red LED flashes approximately every 55 seconds accompanied by a “beep” sound. Easily determine if the alarm has sufficient power
【Silence and Test Button】The smoke alarm is equipped with a silence/test button. If a false alarm is triggered by activities such as grilling or cooking, simply press the button to silence the alarm and activate silent mode. It is recommended to test the smoke alarm monthly using the test button
