About this item
- 10-Year Electrochemical Sensor: This CO detector features a 10-year service life and is powered by replaceable AA batteries with a 1-year battery lifespan. It adopts a clear LED display to show real-time CO concentration. The detection range covers 10 ppm to 999 ppm. Compliant with EU standard EN 50291, it accurately detects tiny carbon monoxide leaks and builds a reliable safety barrier for you and your family.
- Intelligent Device Status Warning: Built-in triple smart alert functions including low battery reminder, device fault alarm and status indicator light.The yellow LED flashes once every 60 seconds and emits a beep, indicating low battery power; The yellow LED flashes three times every 30 seconds and emits two beeps, indicating a device malfunction; The red LED flashes four times every 5 seconds, and the alarm sounds in sync with the flashing of the red LED, indicating that CO has been detected; Equipped with an 85 dB loud alarm, this carbon monoxide alarm lets you keep track of its working status at all times, providing 24/7 all-round protection for your family.
- Selectable LED Flashing Modes: This carbon monoxide alarm comes with two switchable LED light modes. When enabled, the green LED flashes once every 60 seconds to indicate normal operation without harsh light. When disabled, all lights and screen backlight turn off completely, so it won’t disturb your sleep at night. Simply double press the TEST button to switch modes quickly. This feature is ideal for people with sleep disturbances.
- Peak Value Memory: The peak value memory function records the highest CO concentration value triggered an alarm during the latest operation. The record will only update after device restart or a new alarm with higher CO reading, helping you troubleshoot potential hazards and keep track of dangerous conditions accurately. Equipped with a 3-day smart reminder: once a CO alarm is activated, the detector will send alerts continuously for 3 days. The red LED flashes twice rapidly and beeps twice every 50 seconds. You can easily turn off the reminder with a single press on the TEST button. It ensures you never miss safety alerts without unnecessary disturbance, keeping your home fully protected.
- Low Concentration CO Warning: When the CO alarm senses the CO concentration exceeds 20 ppm and remains below the minimum alarm sensitivity for over 35 minutes, the red LED will flash once and produce one beep every 3 minutes. This practical feature is ideal for vulnerable groups such as children, pregnant women, the elderly, as well as those with respiratory diseases, heart disease and other health conditions.
- Flexible Installation: You can choose to mount it on the wall using screws in the kitchen, hallway, or stairwell, freeing up countertop space; or place it freestanding on any flat surface, such as a desk, nightstand, or bookshelf, no drilling required, just set it down and use it. With compact dimensions of 105 × 60 × 33 mm and a sleek design, carbon monoxide detector blends seamlessly into any home décor.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
