Combined smoke and carbon monoxide detector with digital display and audible and visual alarm, battery-powered 2-in-1 smoke and CO detector for the home, travel or camping

CO Smoke Detector

The combination smoke detector and CO detects 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.

High-precision electrochemical sensor (the most accurate CO sensor)

Infrared photoelectric sensor (the best sensor for detecting smoke while minimizing false alarms)

LCD PPM concentration

The Combo Smoke and Carbon Monoxide Detector is easy to install

Works with batteries for More Convenience

3 x 1.5V AA dry cell batteries (packaging not included)

After installing 3 batteries, you will hear a "beep" sound and it will begin to operate normally after 2 minutes. When in operation, it displays nothing thanks to its energy-saving design. Ultra-long standby time, low power consumption.

Press the "test" button and the smoke and carbon monoxide detector will trigger an alarm ≧ 85 dB, loud enough to alert you to danger, whether you are sleeping in the bedroom or watching TV downstairs.

So easy to install wherever you stay for extended periods: Drill the two marked mounting holes. Hammer the two plastic eyelets into the holes. Mount the bracket to the ceiling by inserting and tightening the screws provided into the plastic eyelets. TIPS: Please install the sirens 0.3 to 1 m below the ceiling, as the concentration of carbon monoxide and smoke is lower than that of air. src="https://cdn.manomano.com/external-resources/AAHKMJXYDAFdJAOAIMEbOAchMsjc3QZBtjSFHA9dqEpXPSB65XDJrhSVyThN g87jDURivsIQioVkU4HdlEVCOvmJqupLSMDIfZUAQ_v3XTYZwxYwvLYpRNbL-B2xWc_WZQ_hJ6vRmqFJ5Ws6R5UhYuRgl2Lb0Q1JY1FLWEBDM2 0PIDW6G-uvRZXz8yF5RyZ-KltnGDHXzGyOvBZYd8vSKakEEKAHMqnz8AGTCTixzHABTClZ6I2hPynsTI7sTjmHr5NKxZzyVyCZzJ2lh3D9VpQ vKDP0SF2CsZdSAnDe7pSPescirP1j_h_P8ftLWaW4JogYRAe5yDIXUkbAcwRwyENg-LpRzOTz7Zsurq40hco2UBUDD2CK9i5GNwaPxQ9g4m4=" data-orig-src="https://cdn.manomano.com/external-resources/AAHMJXYDAFdJAOAIMEbOAchlkWZ0oakZn_uVZ0mPidMNbILvCvspZ4oG3fPgIqc1P26RdPiG8KHKUtblW5_ULKvLD1OHzwX-jolGWPZGyLZfAixvs1sfKNf_yLUEjOSBySw6GyD0VkoSGFB3F3jqrwVqw9GtpFmBgTUJGpf6zq1zm65jl7sf-5s3tNQHfSZ3_sllbwIwO3AqiWVRnMFvQrw" />
