## Questions & Answers

**Q: What is the difference between the kidde kn-cope-ic ac ($50.54)and the kidde kn-cosm-iba ($33.93)?  why is one more expensive than the other?**
A: Hello.  The KN-COSM-IBA is an ionization smoke and carbon monoxide alarm with the ionization technology for detecting smoke. The KN-COPE-IC is a photoelectric smoke and carbon monoxide with the photoelectric technology for detecting smoke. 
The KN-COSM-IBA uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms. The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor – which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires – with that of an electrochemical sensor, which is used to detect CO. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm.

The KN-COPE-IC uses photoelectric technology that uses light to detect smoke.  In the alarm is a light and 90 degrees from the light is a light sensor.  When there is enough smoke that the light lights up the smoke and the alarm can see the smoke and light, the alarm goes off.  This kind of sensor is much less likely to give you nuisance alarms due to steam and heat and humidity like cooking or from a shower. 

Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fires that can occur within the home. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms.

**Q: I’m getting false alarms from this, which I installed less than 3 years ago. I thought photoelectric sensors are less likely to give false alarms?**
A: We have had this for just a few months and keep having the same issue. We have done all the troubleshooting methods and it keeps happening. Even though these are only 3 months old we are getting new ones since the false alarms are so awful. I do not recommend this product.

**Q: Is this wired unit (kn-cope-ic)  compatible with the wireless unit rf-sm-dc?  i need these to trigger the other detector alarms.**
A: Hello.  This alarm only interconnects through a 3 wire circuit through wiring. The only hardwired unit that will work with the RF-SM-DC is the RF-SM-ACDC.  If you require wireless alarms with carbon monoxide, you may need to change over to our P4010 wire-free smoke alarms and smoke and carbon monoxide alarms.  The P4010 alarms will not work with the RF-SM-DC.

**Q: Where is it made**
A: Why constantly ask this question?  Everything is made in China on this site.  If you want it cheap then it's not made here.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    had to replace our old detectors
  

*by D***R on Reviewed in the United States on August 30, 2023*

These last for ten years.  Our old ones started going out.  They beep twice every 30 seconds.  The dogs were terrified.  So we took out the ones that died, found the replacement number on the back, and ordered new ones.  Since our wiring was still in place from the old detectors, this was super simple and easy to do.  Even better, they were originally going to take almost a month to arrive.  Luckily they came in about two weeks.  I was also able to order in a quantity of six, which was what I needed.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works as advertised
  

*by S***Z on Reviewed in the United States on July 4, 2022*

I used these to replace 12 year old Kidde models because they started having too many false positives. The wiring harnesses fit seamlessly and the mounting brackets were very easy to swap out. The voice and warning beeps are very loud and one unit triggers the rest throughout the house (using the test button and all wired units).

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Loved the Install!
  

*by A***R on Reviewed in the United States on February 4, 2023*

I replaced six hard-wired smoke detectors with these combo smoke/carbon monoxide units. I specifically picked Kidde so that the wiring connection would be the same, thus eliminating the need to mess with the wires in the ceiling. Made things very easy.Warning: Be aware that half the alarms went through a self test once I pulled the tab on the battery. (Every test sets off every alarm in the system, and it is loud!)Suggestion for bifocal or progressive lens wearers: Grab your computer glasses; you're going to be right up top with the ceiling and the near-vision lens help prevent craning your neck.Final comment: I thought that carbon monoxide testers need to be relatively close to the floor, so I have kept the two detectors that were already installed in place. Just me.
