Key features

• •【Dual-Sensor Photoelectric Detector】Our smoke detector employs a dual-sensor photoelectric technology, offering high sensitivity to smoke, low false alarm rates, and extended service life. It excels at detecting slow-burning fires, responding swiftly even to faint smoke and smoldering fires from soft furnishings or appliances.
• •【Ready to Use Upon Arrival】The package includes 2 pack of smoke detectors, the required number of batteries, base stickers, and a base screw set. Installation is simple: just secure the base to the wall and rotate the alarm to snap it into place (Note: Batteries must be installed for the base to snap securely). No additional accessories needed.
• •【Extra-Long Battery Life】The high-capacity 1.5V AA batteries included in this package feature a large capacity and low natural discharge rate, delivering significantly longer battery life than other common batteries. Our smoke detectors consume less than 0.1 microamperes in standby mode, providing you with long-lasting safety protection.
• •【Low Battery Alert】When battery power reaches the threshold, the alarm's red LED flashes approximately every 55 seconds, accompanied by a "beep-beep" warning sound. Easily determine if the battery is functioning properly.
• •【One-Touch Mute/Test Button】 The smoke alarm is equipped with a mute/test button. We recommend using the test button monthly to verify the smoke alarm is functioning properly. In the event of an accidental false alarm, simply press the button to stop the alarm.
• •【ABS Material】Its internal circuitry and ABS material housing ensure normal operation at temperatures ranging from -10°C to 50°C and relative humidity up to 95%. Safety is guaranteed even in extreme weather conditions.
