Dual Sensor Carbon Monoxide and Smoke Detection Alarm Battery Operated

CO and Smoke Detector with LCD Display Electrochemical Sensor and 85 Decibel Alarm

It builds up with no way to detect it, most homes have nothing in place to catch carbon monoxide in time. It has no color or smell so nothing warns you it's there. Get CO and smoke alerts whether you're home, at work, traveling, or in a dorm.

A continuous CO sensor samples the air and logs current levels to the LCD. Hit a threshold and the LED turns on, the screen updates, and the alarm fires. A smoke sensor runs alongside so both event types trigger the same combined system.

Three AA batteries let you place it anywhere without needing a nearby outlet. Up to 36 months per set means you drop batteries in and forget about them. Included screws go into any wall or ceiling surface in just a few minutes.

This LCD actively shows system status including any errors the moment they appear. Past high CO readings stay logged so you can check the alert history anytime, and pressing the self-test button confirms the alarm and sensor work on demand.

• ELECTROCHEMICAL CO SENSOR: Continuously samples the air and logs current CO levels directly to the LCD in real time.
  
  
• 85 DECIBEL ALARM: Fires the moment a threshold is crossed and cuts through any background noise in the room.
  
  
• LCD CO DISPLAY: Shows live carbon monoxide readings, system status, and error flags all on one clear screen.
  
  
• FLASHING LED ALERT: Red LED switches on alongside the alarm so the visual signal backs up the audio every time.
  
  
• SMOKE DETECTION FUNCTION: Runs a parallel smoke sensor so both CO and smoke events activate the full combined alert.
  
  
• 36 MONTH BATTERY LIFE: Up to three years on one set of three AA batteries before any replacement is needed.
  
  
• SELF TEST BUTTON: Press it on demand to confirm the alarm, sensor, and display all respond the way they should.
  
  
• HIGH CO MEMORY: Logs a history of past dangerous CO readings you can pull up and review at any point.

Frequently Asked Questions

Does it need to be wired into the wall to work?
No, the unit runs entirely on three AA batteries so you can mount it on any wall or ceiling surface without needing an outlet nearby or any hardwiring during installation.

How do I know the detector is still functioning between alert events?
The LCD continuously shows system status and flags any errors the moment they appear, and the self-test button lets you confirm on demand that the alarm, sensor, and display all respond correctly.

Does it only detect carbon monoxide or does it cover smoke as well?
It covers both, a parallel smoke sensor runs alongside the CO sensor so either hazard type triggers the full combined alert including the 85 decibel alarm, flashing red LED, and LCD screen update simultaneously.

How long do the batteries last and are they included in the pack?
One set of three AA batteries powers the unit for up to 36 months before needing replacement, though the batteries are not included so you will need to have them ready before the first use.
