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 monitoring and a wide detection range. Suitable for carbon monoxide and chimney leaks. Once the smoke and carbon monoxide detectors detect these two gases, they emit 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 see the current CO concentration and the machine's battery level status. 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 standard: 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 know the alarm's operating status; The test button allows you to test the alarm weekly (silent mode). When you encounter a non-urgent situation (false alarms occur), 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; easy to mount on any wall or ceiling with the screws provided; You can hear the low power alarm when the power supply is about to run out, giving you the opportunity to change the battery. Note: the battery is not included in the packaging (batteries are not supplied). Carbon monoxide is lighter than air; it is recommended to install it at a distance of 30 cm from the ceiling.
