## Questions & Answers

**Q: I'm confused. what is the diff on the $198.07 (detector) and the $233.16 (detector + co alarm)? they both state smoke + co and have the same specs?**
A: The $198.07 (detector) is a 6 pack of the hard-wired combination CO + Smoke detectors (model ‎KN-COSM-IBA). The $233.16 (detector + co alarm) is the same pack (6 of ‎KN-COSM-IBA) but also includes an additional CO + Smoke detector (model KN-COSM-BA) which is BATTERY POWERED not hard-wired.

I was super confused until I selected the $233.16 (detector + CO alarm) option and found the section that read "This bundle contains ___" to see what actually was included.

**Q: Replacing Firex 120-1182 (smoke detection only), are there any incompatibilities if replaced with this newer smoke and CO2 detector?**
A: The new connection comes with it, but if you wish to save time and effort buy the connections that pop up when you get ready to purchase it made it quick and easy.

**Q: If someone remove the battery, will the unit somehow notify us that it is missing such as a chirp or a flashing light?**
A: Hello. The unit will chirp every minute and say "Low Battery" in a voice.

**Q: Can these be interconnected with battery-only versions? If so, what is the compatible battery-only version? (I have 3 hard-wired connections and want**
A: I don't believe that you can mix battery with hard wire ones. For a definitive answer, contact Kidde service. I found them very helpful when upgrading my equipment.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Updated Review - Don't Rush To Judgment
*by A***R on January 19, 2025*

I ordered this product because I wanted to get the same type of fire alarm to make it easy to set up. This is an updated version of the previous old one, but what make it great is that it comes with an adaptor for easy set up, just clip it on. My bad!

### ⭐⭐⭐⭐⭐ Excellent Product!
*by M***E on November 24, 2024*

Works very well, thanks!

### ⭐⭐⭐⭐⭐ Easy to change batteries.
*by D***A on March 31, 2025*

This was a replacement for an older smoke detector. My super installed it in minutes (just plugged into the connecting wires already in place). I particularly like the fact that I don't need to pull the unit down to replace the batteries but can simply slide the door open on the unit's front side.
