Fire & CO Detector in 1 unit with alert modes, LED light, test-silence button, & Replacement Alert: a chirp that notifies when the unit needs to be replaced.
Electrochemical sensing technology - CO alarm detects the presence of carbon monoxide gas, 85 decibel alarm.
Protects during a power failure - CO detector operates on a sealed, lithium battery.
Easy installation & no battery fuss - CO alarm will automatically activate when attached to the mounting bracket.

2-in-1 Protection: 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.
10-Year Battery: The fire and CO alarm is built with a sealed lithium battery that provides 10 years of continuous power, saving you from changing batteries and power outage.
Combination Alarm with CO Readings: The informative LCD will show you the battery level and real-time CO levels in PPM (parts per million).
Simple Installation: Requires no rewiring.
easy to mount this smoke and carbon monoxide alarm on any wall or ceiling with the included mounting bracket, screws, and anchor plugs.
Informative LCD: Displays real-time CO levels from 30–999 ppm (parts per million) taken from the surrounding air, as well as battery level and working status.

10-Year Battery Smoke and CO Detector: Provides 10 years of continuous power with built-in lithium batteries.
Combination Alarm with CO Readings: The informative LCD display clearly indicates real-time carbon monoxide (CO) levels in the surrounding air, as well as its battery level and working status.
2-in-1 Protection: The smoke and carbon monoxide detector is equipped with both photoelectric smoke sensor and electrochemical CO sensor that both detect smoke and dangerous CO levels.
Practical LCD Display: Clearly indicates real-time carbon monoxide (CO) concentration in the surrounding air, as well as the remaining battery life and working status of the alarm.
if a CO concentration of 30-999 ppm exists for a certain time period, the screen will be backlit blue, and the LED indicator will flash red 4 times every 5.8 seconds.
Simple Installation: Requires no rewiring.
easy to mount this fire and CO alarm on any wall or ceiling with the included mounting bracket, screws and anchor plugs.

Keep your family safe with this easy to use, battery operated carbon monoxide alarm.
Battery powered alarms provide continuous monitoring of CO levels, even if there's a power failure.
Features an advanced electrochemical carbon monoxide sensor that accurately detects carbon monoxide levels, no matter where the detector is placed in the room.The alarm sequence should last 5-6 seconds. If it does not alarm, make sure fresh batteries are correctly installed, and test it again. If the unit still does not alarm, replace it immediately.
A loud 85 decibel alarm sounds when CO levels reach dangerous levels.
To ensure complete protection make sure to place one on each level of your home and in each bedroom.
Equipped with end of life signal chirp, so you know when it’s time to replace the unit for safety.
All first alert CO alarms are rigorously tested to meet UL standards.
First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958 (Based on a First Alert Brand Trust Survey in February 2018).
