Combined carbon monoxide and smoke detector, dual-sensor CO smoke detector

Accurate, Reliable, Highly Sensitive: Compliant with the latest EN 50291-1:2018 standard, equipped with photoelectric and electrochemical CO sensors that operate independently. When carbon monoxide and smoke reach alarm levels, the CO sensors detect CO, the red LED flashes, and the alarm emits a loud 85-decibel warning sound when detected. The photoelectric sensor detects smoke while minimizing false alarms. It provides dual protection with uninterrupted coverage and a wide detection range. Suitable for carbon monoxide and chimney leaks. Once the smoke and carbon monoxide detector detects both gases, it emits a beep. Package contents: 1 carbon monoxide and smoke detector, 2 expansion screws, 2 anchor bolts, 1 user manual. LCD Digital Displays: You can use the digital display to view the current CO concentration and the machine's battery level. The screen displays a wide range of real-time CO levels from 000 to 999 ppm. The alert time depends on the carbon monoxide concentration level. Alarm settings: 50 ppm, alert within 60 to 90 minutes; 100 ppm, alert within 10 to 40 minutes; 300 ppm, alert within 3 minutes. Test Mode Button: Malfunction and low battery warnings allow you to easily monitor the alarm's operating status. The test button allows you to test the alarm weekly (silent mode). In non-urgent situations (false alarms), you can immediately press the test button, and the LED indicator will flash cyclically, indicating that it has entered silent mode. The LED indicator flashes once every 10 seconds, indicating that the alarm has entered silent mode. Quick and easy installation: Battery-operated device. Can be easily installed and maintained without the need for an electrician. Easily mounts to any wall or ceiling with the included screws. You will hear the low-power alarm when the battery is about to run out, so you won't miss the opportunity to change the battery. Note: The battery is not included in the packaging. Carbon monoxide is lighter than air; it is recommended to install it at a distance of 30 cm from the ceiling.
