FireX photoelectric combination alarm offers protection from two hazards - fire and carbon monoxide in one unit. Hardwire with battery backup alarm emits a beeping tone followed by a voice warning that clearly announces the danger: "Fire. Fire. Fire". or "Warning, carbon monoxide".

  • Combination alarm utilizes photoelectric smoke sensor technology and electrochemical carbon monoxide sensor
  • Equipped with smart touch button that activates the hush feature, tests the unit's electronics and verifies proper operation, activates the peak level memory feature, resets the unit during a carbon monoxide alarm, silences a low battery chirp for up to 12 hours and silences the end of life chirp for two days
  • Tamper resistant - unit will lock to mounting bracket and battery door will lock to deter theft or tampering
  • Front load battery door, speeds up replacement by eliminating the need to remove the unit from the ceiling or wall
  • 9-Volt battery back up (included)

Rated 4.4 out of 5 by 142 reviewers.
Rated 5.0 out of 5.0 by Easy To Wire I have 4 hardwired smoke alarms in my home that needed to be replaced from old age and the lack of a battery backup. I had no idea what to expect from the original wiring, wiring harness, mounting hardware or operation of the new alarms. I did expect another trip to the store would be involved somewhere. To my surprise I was able to replace all 4 alarms with new combination alarms, rewire the harnesses and finish installation in less than an hour. Operations test was a surprise also, first a voice announcing type of alarm fire or CO2, then unique high decibel alarm for each, all 4 alarms sound the alert. I am very happy with this purchase.

Rated 1.0 out of 5.0 by FALSE ALARMS driving my family nuts!! In short, these models are prone to false-smoke alarms @ random hours during the night. I am certain there is nothing wrong with the wiring more installation in any way. These are simply a poor design. I have had no issued with the competing brand I was previously using before I replaced them with these new units. Out of 8 alarms in my system, I have already had to exchange TWO faulty units so far in the first 2 months of use. These are suppose to be guaranteed for 10 years?! Read the bad reviews on Amazon & Home depot that reflect that this is NOT an isolated issue November 19, 2014
Rated 2.0 out of 5.0 by False alarms after 6 months use Have installed 3 of the Kidde units model KN-COPE_ICCA but one of the units starting giving false smoke alarms at all different times of day/night after six months of usage. Took it back to Home Depot, who replaced it for no charge. The alarms can be very annoying and bothersome to pets. We vacuumed the unit after first few alarms to no avail. I would expect it to perform better especially with a 10 year guarantee. January 20, 2015
Rated 1.0 out of 5.0 by Do not buy this brand combo false alarms every day I wish I can give negative rating to this combo alarm from Kidde. It goes on by itself every night or day and says Fire Fire and there is no fire around in any of the alarms. I got these upgraded 6 months back during my house renovation. I would advise that stay away from these and do not waste your money and sleep by purchasing these alarms. January 18, 2015
Rated 4.0 out of 5.0 by Great combo unit I bought 3 of these to replace 3 ancient interconnected BRK units that did smoke detection only and had to be from the 1980s. I also bought adapters so that I could reuse the existing wiring harnesses. It was a pretty straightforward install. I love now having CO detection in addition to smoke, plus the voice feature, plus the battery backup - all new for me. I had 1 false alarm 2 nights after the installation, but I believe it was due to an improperly seated connector/adapter. After addressing this, it's been at least a month and it hasn't happened again, which is good since I went with this brand because of all of the false-alarm complaints of other brands. April 4, 2013
Rated 5.0 out of 5.0 by Safety first Love the hard-wired battery back-up features. Price is good for the item. May 24, 2015
Rated 2.0 out of 5.0 by FINE...UNTIL THEY START BEEPING WHEN THERE'S NO SMOKE We put a half dozen of these smoke detectors in our new home, and everything worked great for the first 5 months. Then 3 of the 6 alarms started sounding every 2-3 minutes, even though there was no smoke and even after we tried replacing the batteries. We eventually had to take them all down and replace them with another brand. The experience made us wish we didn't have 10 foot ceilings! March 13, 2015
Rated 1.0 out of 5.0 by Do not buy this product These detectors and related photoelectric only detectors constantly false alarm. During dry winter months everything is okay. When summer high humidity is present they false alarm. These detectors do not have insect screens This year we had to remove the all 9 units in the summer because of humidity, had recently cleaned and reinstalled with new batteries, then false alarmed again yesterday, apparently due to lady bugs. Contacting Kidde is most unhelpful and unfriendly, both by telephone and on line. I have just ordered Gentex GN-303 detectors; Gentex has a good reputation in the industry (i'm a retired electrical consulting engineer). By the way I originally purchased USI detectors from HD and they were as bad or worse than the Kidde units also purchased from HD. So in 6 years, I'm on my third replacement, therefore not a happy customer! October 16, 2014
