About This

• [SHYEEH Plug-in Combination Gas and Carbon Monoxide Detector] This is a plug-and-play two-in-one natural gas and carbon monoxide detector, which is not only equipped with an LCD digital display with smart screen-off and a buzzer greater than 85dB, but also has continuous low-concentration alerts, product life expiration alerts, and malfunction alerts
• [Smart display&85dB buzzer] Equipped with sleep-friendly design(auto screen off after 30 seconds of inactivity, but still working) and easy-to-read digital display, paired with >85dB buzzer. Ensures your sleep quality while providing sufficiently loud alarm to wake you for immediate action
• [Aerodynamic Design] Adopts triple-side honeycomb air inlets for faster detection of CO and gas concentrations in the air, allowing timely identification of potential household threats and providing maximum protection for your family's safety
• [Continuous Low Concentration Alarm] Our alarm system will not only sound an alarm when the CO concentration reaches 150ppm, but also when the CO concentration remains at a low level: 50ppm (alarms within 60-90 minutes), 100ppm (alarms within 10-40 minutes), and 150ppm (immediate alarm). PS: The gas concentration display starts at >3% LEL, and an immediate alarm is triggered when it reaches 8% LEL. The gas display upper limit is 20, and any alarm with a value >20 indicates CO leakage
• [Fault and End-of-Life Alert] The test/mute button on our product features multi-color indicator lights: Solid green indicates normal operation; blinking green indicates preheating (60s when first powered). Solid red indicates active alarm ; solid yellow indicates sensor fault (replace immediately); blinking yellow indicates end of product life (replace immediately)
