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 136 reviewers.
Rated 5.0 out of 5.0 by excellent fire and carbon monoxide talking alarm This excellent fire and carbon monoxide talking alarm is easy to install and batteries last more than a year, it is a must to have if you care about fire or carbon monoxide inside your dwelling. Two years ago after a city inspection recommendation, I installed two in my unit and now installing 3 more in other units. September 20, 2016
Rated 1.0 out of 5.0 by i bought this on 03/25/14 and installed it. i have always replaced the batteries when it is time change the clocks and test it to be sure it is working. So i changed batteries today 10/27/16 and tested the alarm. It does not work! Now i wonder how many months it has not been operating. Remember that just because it has a 10 year warranty it does not mean that it will work for 10 years. October 27, 2016
Rated 5.0 out of 5.0 by received on schedule, test works, installed on same screws as old unit of different brand that was at least 15 years old and I wanted one that would not be subject to age limits. No CO sources in house, total electric but installed near garage door in case something leaks from there. October 25, 2016
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 Carbon Smoke Detector Product was easy to install seamless replacement for an older version. Product ordered on-line and was received within the estimated delivery time; pick up at the store was effortless. October 18, 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
