Answer: 
Hello Funny, This alarm does not have a solid green light. A solid green light is an indication that the alarm is receiving AC power when in standby mode. This alarm will not have a solid green light as it is battery only. On this unit, standby mode is a single green flash every 60 seconds. Please call Product Support at 1-800-880-6788 if you have any additional questions. Thank you.

Answer: 
Hello GW, The KN-COSM-BA will fit the same base, however, it is a battery only device. The direct replacement for the KN-COSM-IB is the KN-COSM-IBA . It will fit the same bracket, but also the same wiring harness. Good question, Thank you.

Rated 4.5 out of 5 by 120 reviewers.
Rated 5.0 out of 5.0 by You need this! Your life may depend on it! One unit serves 2 functions! Fire or CO means alarm! Get out! Put in the battery. Simple to mount. Save the lives of your loved ones. Can't beat that! June 14, 2016
Rated 5.0 out of 5.0 by Makes me feel safer I have a condo and I saw on the news where some people lost their life from Carbon Monoxide in a building similar to mine. It immediately dawned on me that I should get a Carbon Monoxide alarm. For a minimal cost, I think it is worth the potential life saving benefit and with the Smoke Alarm built in, the value is increased even more. May 3, 2016
Rated 4.0 out of 5.0 by Great Purchase This detector makes it easier to change the batteries. The battery department is now located on the face. I don't have to take the whole thing down. I also like it having a carbon monoxide alarm. Two alert in one saves ceiling space. I had one previously, over 5 years, and it just started alarming. I changed the batteries, but that did not stop it. I replaced the old one with a new one and everything worked out fine. March 21, 2016
Rated 5.0 out of 5.0 by very safe item The smoke detector is very good and makes me fell safe. It was easy to hank ans add a battery. June 25, 2016
Rated 5.0 out of 5.0 by Review Easy to install and seems like a quality product that we hope we will never hear going off !! June 24, 2016
Rated 5.0 out of 5.0 by So Far So Good! Installed this guy on my main floor near the kitchen about 2 months ago and so far I've had no false alarms due to cooking, which was really my only concern. Super happy that an affordable alarm has been so good! June 7, 2016
Rated 5.0 out of 5.0 by Excellent product, works really well! I had purchased the same smoke & CO detector 7 yrs. ago. This was a replacement with an improvement. You can now put the batteries in without having to take the unit down from the wall or ceiling. There is a "door" on the face of it. Good product! June 7, 2016
Rated 5.0 out of 5.0 by Detector it a small 2 in 1 smoke and carbon detector, I got 4 for my house and fast install (2 small screws) and Really loud! plus for the price cant go wrong. June 7, 2016
