Smoke and carbon monoxide detectors, battery-powered smoke and carbon monoxide detectors with LCD display and voice alert

Smoke and carbon monoxide detectors offer excellent safety by triggering an audible alarm when smoke or carbon monoxide is detected, allowing for immediate alerts to at-risk individuals and ensuring personal safety. Integrated high-precision electrochemical and infrared photoelectric sensors provide high stability and sensitivity, thus reducing false alarms. An alarm memory function saves the last test, making the next test more sensitive. Low power consumption, long standby time, powered by 3 AA batteries (not included), low battery indicator. Alarm concentration: 50 ppm, 60-90 minutes; 100 ppm, 10-40 minutes; 300 ppm, 3 minutes. The combination of carbon monoxide and smoke detectors allows for the installation of a single detector where two were previously required. This reduces installation time and preserves an attractive aesthetic. The silent mode function temporarily eliminates false alarms. If the alarm detects a CO concentration equal to or greater than 100 ppm, the device will sound an alarm to warn of the presence of CO when the Test/Reset button is pressed.
