My house was built in year 2000 with FIRE X model FADC smoke detectors. The master bedroom detector failed after 4 years ( false alarms). The replacement smoke detector, (same model) built in 2004 failed the same way in November 2008.
Consumer Complaints & Reviews


We have Firex smoke detectors in our house. They are hard wired into the house and if one rings they all ring. One is faulty indicates a need to change batteries even after a new one has been put in. It inexplicably will set off all the other detectors on a regular basis usually about 4:am
Many batteries, many rude awakenings

We bought four new FireX smoke alarms, one being the more expensive model for use in kitchens. After just two months of installation is it emitting a 3 alarm-pause-3 alarm pulsating tone. Very annoying! We assumed it was a dead battery but that is NOT the case. After installing one of the recommended 9V batteries, it continues to emit this alarm. PLEASE REPLACE OR REFUND OUR $19.00 PURCHASE PRICE. Thank you ! A reply would be greatly appreciated
Our $19.00 purchase price, plus the cost of replacement batteries that did not correct the problem. No receipt was retained -- we assumed we had a quality product.

We have 3 G6 firex smoke detectors in our home (we've lived here 10 years & the home is 13 years old). We've never changed the batteries because we cannot figure out how to do so. Can you please advise? Is there anyone in our area who can inspect and/or replace our smoke detectors?

FYI THE SMOKE DETECTOR PURCHASED AND INSTALLED IN 2000, FIREX MODEL FXW-R SERIAL NUMBER 99091 HAS SHORT CIRCUTED HEATING UP THE CIRCUIT BOARD AND MALFUNCTIONED. THE UNIT WAS NOT CONNECTED TO ANY OTHER DEVICE BUT A STAND ALONE A/C POWERED DETECTOR.

i bought my house brand new and it came with your firex carbon monoxide detectors. after six months the detectors started to churp. i replaced the battery and 8 hrs. later the darn thing started to churp again. so i thought it might be a bad battery, it wasn't the unit and all 4 units that i have in my house are doing the same thing? WHY???? I have 5 children and 2 gas fireplaces, you do the math! I have currently got a temporary co2 detector, while waiting a response from firex? please act fast co2 is no joke! thank you

I have a Firex smoke detector Model 120-557B.I was doing a routine monthly check and found the alarm not working. Battery was good but the alarm was so faint you could never hear it unless you were on top of it. I have always purchased Firex detectors because I thought they were the best on the market. This really upsets me to know that the alarm went bad and If I hadn't have checked it I never would have known. I also put these detectors in my rental property's. What's up with these things?

In February of this year, I purchased a pro pak of firex ADC smoke detectors at Home Depot. After installing and interconnecting them I discovered that the interconnecting capability of the alarms did not work on any of them. Home Depot could offer no other choices for the 120 volt and interconnected alarms so I purchased another package of another brand.

In January I bought at Home Depot three new Firex smoke detectors with 10-year lithium battery.
One detector does not sound with test or with smoke. Mfg date is Sept. 24, 1999. A representative said they would send a replacement in about one week. My concern is how many detectors are out there that are defective like this.
This is why every smoke detector should be checked at least once a year. Also, we've forwarded Timmi's report report to the U.S. Consumer Product Safety Commission.
