First Alert Combination Smoke and Carbon Monoxide Alarms work exceptionally well in detecting smoldering fires. Leaps in ingenuity and technology have allowed this alarm to successfully decipher between nonhazardous and potentially life threatening smoke patterns.

This alarm comes equipped with a Mute Button that serves the dual purpose of quickly silencing your alarm as well as testing its function.
Combination Smoke and Carbon Monoxide Alarms utilize an Electrochemical Sensor that allows for optimal efficiency in detecting carbon monoxide. This alarm also comes equipped with an EZ access battery door that removes the hassle and burden of collecting your alarm from the ceiling and replacing its batteries. The combination of an End of Life Timer and an increased emphasis on the unit's 85db sound output establish peace of mind, while the inclusion of Dual Smoke and Carbon Monoxide Sensing all but guarantees the safest of experiences.

I currently have these in my rental unit. As I will soon be closing on my first house, I needed to purchase several combo smoke/carbon monoxide detectors. I immediately went for these because I haven't had any problems with these units in the last six years I've been using them in my rental.
great product - 11/22/2018

I saw this at a store and it was more expensive. So when i got a chance to buy it online I did. It was so easy to put up and now my mother in law will have the protection she needs. I am going to get another one also for me. Ours is pretty old. It has great features.

First time installing a carbon monoxide alarm, hit the test & wants sure if the alarm would turn off it did, but the peace of mind knowing this is in place is well worth the cost.

I had to look through several stores to finally realize, the only place I could replace my smoke alarm was by your web site. I am perfectly satisfied and trust my life with your products. Thanks

The First Alert smoke and carbon monoxide alarm in our motor coach reached its end of life date and so I was looking for a similar unit to replace it. Looked on Amazon, Granger and a few other suppliers. None had a proper description of the unites they were selling. Some where higher priced a few were lower priced but nowhere did they assure me that the alarm I was getting was a current product and not something that had been sitting on a shelf for a couple of years. The First Alert site was easy to understand what I was buying. The product came quickly.

I ordered this to replace an existing smoke detector. Like that both carbon monoxide and smoke detector are combined and that new detector fits into existing hardware

Battery Smoke and CO Alarm - 04/19/2018

Nice unit arrived promptly and easy to install.
Actual battery service life depends on the particular design of your smoke or carbon monoxide alarm and the environment in which it is installed. All kinds of alarm batteries specified in the user's manual are acceptable replacement batteries. Regardless of the manufacturer's suggested battery life, you MUST replace the batteries immediately once the unit starts "chirping" (the "low battery warning"). It is recommended that you change the batteries in your alarms when you change your clocks for daylight saving time. Also consider replacing your current alarms with 10-Year Life Alarms that never require a costly battery replacement for the ten year life of the alarm. This 10-Year series is available in smoke, carbon monoxide and combination alarms.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
