General description Carbon monoxide detector LM 201A is a certified and tested device according to EN 50291. It features a display that shows temperature, CO concentration, battery charge level, operational monitoring, and alarm status, along with three colored LED indicators to indicate the status of the detector. The detector includes a self-test function and a TEST button for manual testing, as well as an error warning for malfunctions and a warning signal for low battery. It provides an early warning system for different CO concentrations, activating an alarm at dangerous levels of carbon monoxide. In case of a false alarm, the sound can be muted for 5 minutes. Technical specifications Effective detection gas: carbon monoxide Detection method: electrochemical sensor Working voltage: 4.5V DC Working environment: temperature 0°C – 45°C Relative humidity: 0 – 90% RH Quiescent current: 80 ± 10 µA Alarm current: 45 – 75 mA Alarm volume: 85 dB (at 1 m distance) Power indicator: flashes
