    I have an issue with my Kidde fire alarm. I called their customer service number yesterday and after almost 1.5 hours waiting on the phone, I hung up. I emailed them and received a response that they will get back to me as soon as they can, but for urgent calls, call their customer service number. What a joke. I called back today and am currently still on hold after 47 minutes. Unacceptable.

    My house was built in 2006 and has about 10 fire alarms. I left my home and forgot to turn off the stove. Two hours laters, my house was filled with smoke and none of the alarms chirped. Luckily, this was during the day when I was not home. Terrible smoke detector!

    We purchased our two story home with the i4618 interconnecting alarms. They have gone off a time or two while cooking. On 1/5/18 we had a fire in our garage. I woke up to the smoke choking me. We were all sleeping. When I opened my bedroom door to investigate, the entire 2 stories were filled with thick smoke. The garage had an active fire and smoke so thick you could not see. NONE of the 10+ alarms installed sounded. If the smoke didn't wake me up, we could all have been killed. The fire department tested all alarms, and they were functioning when tested. This is deeply concerning. I am waiting for a response from Kidde regarding this issue, however given this experience I would NEVER recommend this brand.

    At 5 am, two mornings ago, I was awakened to all 7 of my fire alarms sounding off. Two are located on the vaulted ceiling, which I could not reach. I had my windows open because it is finally cool in Arizona. I Googled how to stop the alarms, & the only way was to close my windows, & warm up the place. After my dog ran outside to get away from the chirping & 10 minutes later, the alarms were silent. I disconnected the one in the bedroom & waited until the others were silenced. I purchased the home two months ago. These were apparently installed in 2006 when the house was built, but changing the battery in the one in the bedroom did not help. It continued to chirp, so I left it disconnected. Not a pleasant experience at all. If I cannot open my windows on a cool Fall day, then that is a problem! Help!

    I built my own house about a year ago and the electrician installed a bunch of this FireX i4618 throughout my vault ceiling house. About one week ago, one started chirping around 7am. I checked the battery and it was still good. I took this bad one to Home Depot and complained that this is just one year old and it is defective. Home Depot gave me a new one. Today about the same time ~7:45am, the smoke alarm in one of the bedrooms started chirping. I check the battery and it is just like the previous scenario. FireX should go out of business. After reading other reviews, I can't believe me and other consumers kept buying this junk. It cost $15 at Home Depot. Home Depot should stop stocking this junk. Like other consumers, my beloved pooch started freaking out when the smoke alarm squealed.

    These alarms go off for no reason at night from bugs or dust really??? But I can stand there with incense burning and nothing! I can't cook without it going off too! This is an insane way to live!!! We finally had to disconnect one. This helped a bit but still get the alarm at night while sleeping! Do not buy FireX!!!

    Do not buy FIREX or KIDDE (same company) smoke detectors (i4618A). I replaced all of the alarms in my home 1 1/2 years ago. Last night all of my hardwired alarms kept sounding for about a minute, then would shut off and sound again after about 20 minutes. I took down the one that set the others off. It was warm to the touch. I blew it out with air from my compressor, then installed a fresh Duracell battery. It immediately started sounding before I even plugged it back in, and I had to remove the battery to shut it off.

    I called customer service next morning and explained everything that I did. After giving her all the information she asked about the alarm, including the installation date, she asked me the date on the battery I installed. I told her I had just bought them and since they have a shelf life of 5 years, I don't see how it makes a difference, but let me go look. She then said that since I don't think it makes a difference, she has nothing else to say to me and hung up. WORST CUSTOMER SERVICE I HAVE EVER HAD ANYWHERE.

    Original review: May 13, 2017

    We just moved into our house in November 2016. The previous owners installed FireX smoke alarms throughout the house. Model #S1966, 120-1072B. Issue # 64,995. Of course just like other consumers spoke about our living room smoke alarm started chirping late at night. At least 2 high pitched chirps. Our 2 big dogs are freaking out & looking at me like make it stop!!!

    Also mounted on a vaulted ceiling so had to get the ladder from the garage. Had to figure out how to quickly disconnect this from the electrical connection. A solid pull & it was off. I got the compartment open for the 9 Volt battery. By then I am in the garage as the dogs are scared out of their minds! I get the battery out & think "Whew... glad that is over." I bring it back in the house to see if we have any 9 Volt batteries. Meanwhile the smoke alarm is still chirping!! I think what the heck, it is not connected & no battery in it! Dogs are like get it out of here! I take it into the garage & bury it into some old blankets in a box to muffle the chirps.

    We got new 9 Volt batteries & installed one. Mounted it back up on the ceiling. It starts chirping again a lot. My husband took it down & said just smash it. By now both dogs are going to have nervous breakdowns (dog owners will get this). I get a hammer, place it on the garage floor, battery out & smash away. It this point it was fun to do. Just like everyone else stated goes off in the middle of the night. 1 or 2am. So glad I read these reviews. We will be buying a different brand for all the smoke alarms in the house. Our bedroom one had been acting up also.

    Customer service rep was very patience and understanding while we solved the problem. We have 8 i4618 hardwired with battery back up. We took down each unit one by one and removed battery to find the culprit. Then reinserted a new battery... Thank you thank you sir for your help... Sorry I did not catch your name.

    I have the I4618 model. Started beeping downstairs since they are interconnected randomly, then upstairs randomly almost always in the middle of the night, like 2 AM. I also had to run to get a ladder out of the garage to disable this absolute piece of garbage from this absolute piece of garbage of a company in my opinion in the middle of the night to disable several of these as I have vaulted ceilings. Absolute GARBAGE in my opinion. Company should be shut down in my opinion.

    I woke up at 5:00 am to my smoke alarm blaring, ran down the hall and started fanning the thing as there was no smoke present. I couldn't figure out what could have set it off. I reached up and unplugged it (electrical connection) to have a look, the smoke alarm itself was "hot" and so was the ceiling around it. 20 minutes later everything was cooled down. I thought I had an electrical problem but after reading about this brand I think it may have malfunctioned. I'm taking it down to the fire station to talk to them about it. FIREX model #FX1020.

    I just replaced my hardwired Firex i4618A because the old model was chirping. A backup battery change didn't fix the issue. I bought the exact same model, brand new, with another new backup battery, and it worked for only 4 days, then started chirping. The hardwired circuit checks out with my electrical tester. The 4 day new FireX i4618A went right into the trash and I installed a new brand. Don't buy this brand.

    We moved into the house 2010. Shortly after, we had these interconnected alarms sounding, never a chirp, full blown alarms middle of the night of course! We have replaced everyone, still random alarms! Batteries are changed more than twice a year, hard wired, so when one sounds, they all sound! We keep them dust free, blown with Can Air as recommended when we called, company has replaced a couple of them! Still this goes on! One detector is high on a 12ft wall! At 5 am this morning my husband had to scramble into garage to get a ladder to remove it from our living room wall! Meanwhile, we have 2 dogs freaking out, getting them onto the porch! This is NOT ACCEPTABLE! Never any place I've lived have we ever experienced such poor performing smoke detectors! Never smoke, never fire! Never battery issues! Horrible product - FireX smoke alarm i4618.

    Smoke alarm 14618 series - I had five alarms professionally installed in 2012. They go off every time I cook but have had a microwave and an oven fire and they were totally quiet. Then the one in the garage has chirped its way through three new sets of batteries in two weeks, while setting off all the alarms. It is chirping, as I write this. My 4 and 5 year old grandchildren are no longer afraid of firemen and have now promised to bake cookies for them. This is both unacceptable and dangerous.

    I am a general contractor who installed six interconnected type, line voltage with battery back up i4618 alarms in our new house. After a very short period of time alarms started going off randomly, almost always in the middle of the night. I changed all batteries with recommend brand and problems continued. After cleaning all of the units and replacing the batteries once again the random alarms continued. I then replaced all of the units with new alarms, same model (big mistake). After six months or so the random alarms started again. The alarms are all now sitting in a box ready to go to recycle as I review other smoke alarm brands to purchase as I will never allow FireX brand alarms in any house we build.

    I have lived in my newer home for 4 years and have quantity 3 FireX i4618 smoke detectors. I have put new batteries in these detectors twice. This time I put in new batteries (that I tested and voltage was fine) and the detector kept starting to beep a few times a few days following installation of a new battery. I tried 2 different 9 volt batteries that were new and dated 2017 and 2018. I called FireX customer service and was informed that I had to buy a Duracell Alkaline battery that was dated 2019 or later.

    I am an electrical engineer and I believe FireX has a flawed design if batteries only last a year. The units draw too much current from the backup battery and should not draw any current from the batteries unless 115 volt AC power is lost temporarily. We have lost power for a total of 50 hours in the last 4 years. I am replacing all my units with another because I am fed up with being woken up in the middle of the night by a simple device that is there to help you sleep better.

    We built a new house and gained occupancy in August of 2013. Our new home is equipped with 8 Kidde smoke detectors which were installed and interconnected by the electrical contractor. We change the batteries when we change the clocks 2x per year. We vacuum the vents at the same times. We just had our second detector fail - false alarm and subsequent low battery signal that does not stop even after putting in fresh Duracell batteries. The first failure was in the 8th month. Now the second on 12/9/14.

    I checked the worthless warranty from Kidde and it reads as follows: "Return the defective alarm postage paid along with proof of purchase and prepaid return postage and Kidde will evaluate the failed detector and decide if they will replace it or not." This is worthless warranty. It costs more to ship and pay return postage than the unit is worth. Save yourself the hassle and buy another brand of detector. These units are defective and the company does not stand behind them.

    I replaced a hardwired smoke detector in my house with a Firex i4618. Lately the alarm goes off during the night for an unknown reason without setting off the other alarms in the system. This sets off total distress for my family. Could you tell me the reason why?

    Original review: March 27, 2014

    Our dream home was built in 2004. All smoke alarms were installed according to local code. They were interconnected so that smoke detected in one part of the house would sound the alarm on all other smoke detectors throughout the house. Within two years, our smoke alarms from FireX started to fail. Usually they went off at night when we were in the least possible position to remedy the situation. And most were so high on the vaulted ceilings that we couldn't find a ladder longer enough to reach them. But after bothering neighbors at 3 a.m. for example, we would get within reach of the alarm, but needed both hands above the head to remove the alarm from its most difficult receptacle.

    The first two units were mailed to FireX's address in Texas and were replaced. The third smoke alarm was returned by mail to me with an 'address unknown' sticker on the envelope. I consulted the Internet for a new address and found none. After that alarms which failed were simply pulled off the ceilings and put in storage until I could find an address.

    By the time I found a new address for warranty service through Kidde, the Kidde company refused to service or replace the unit because the warranty had expired. Well, duh, that's what happens when the original company moves and leaves no forwarding address. Most companies that take over other companies must honor warranties of previous companies they acquire. In order to comply, the new firm should have mail forwarded and not just return the mail to the consumer. This is why we have to have government oversight of trade because companies often do not do the responsible thing. Smoke alarm requirements by cities and county must look at the situation realistically and must know that these units are difficult to service, almost impossible to remove, and surely a bear to replace.

    Original review: Nov. 22, 2008 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.

    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

    Original review: Sept. 5, 2007

    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?

    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.
