Upgraded Version Dual Sensor Keep Your Safety: Compared with most carbon monoxide smoke detectors on the market, which all use sensors with a three-year lifespan, the detector uses sensors with a 10-year lifespan.So the product has a longer service life.The combination smoke and CO detector detects both smoke and carbon monoxide faster and more accurately using a photoelectric smoke sensor and an electrochemical CO sensor, protecting your home from two potentially deadly threats.
LCD Digital Displays & Multi-directional Sensing Hole: The informative LCD will show you the battery level and real-time CO levels in PPM (parts per million). If there is fire and carbon monoxide with a concentration over 0.1% db/m, the blue light flashes rapidly. If CO is detected, the red light will flash. Dense gas-sensing holes can prevent alarms from causing false alarms and reduce your worries.
