My home was built in 2001, and it was equipped with Firex 120-1072B units in each room wired for interconnectivity. One of my units began to sound randomly even when there was no fire. I tried changing the battery, but I still had the same results. So after searching online, I found that the Kidde i4618 is the current replacement model.
After purchasing the model, I was hoping that I could use an adapter between the wiring in my Firex unit and the Kidde. However, I found that I was mistaken in what I thought I had read. I am about as unhandy a man as they come, and I really wasn't looking forward to rewiring for the new unit. The hardest part of the process turned out finding the correct breaker as mine are not labeled. At least for my house (please know that yours may well be different), the smoke detectors were on a dedicated breaker. Once I found it and switched it off, it was very easy from there. I removed the two screws from the bracket of the Firex unit and then uncapped the wires. The Firex wires were easy to remove. I rewired black, white, and red as indicated and put the yellow caps back on to cover the wires. Then it was a simple matter of screwing in the new mount, connecting the wire, and twisting the Kidde unit into place. Once I flipped the breaker back on, everything was back to normal.
There is one nice thing on these new units. The battery door is on the face of the unit rather than the back. The old Firex unit has the battery in the back, and it was a pain to replace the battery. Another nice improvement of the Firex unit is the power connector is much easier to plug and unplug without being insecure.
So if this is the replacement for your old Firex smoke alarm, don't hesitate to get this one from Kidde. I'm pleased with the results, and I think you will be too. Please feel free to ask questions in the comments section below.

I have installed two of these to replace low squealing broken detectors. Just goes to prove you need to check them annually. Easy to install with no rewiring as they provide an adapter which fits three prongs in a straight line of the old wiring. See picture. Battery easily accessed.

If you're looking to replace existing FireX detectors, I'd buy the i4618 detector in the Item 21007582 pack vice the 21007581 pack because it comes with the FireX to Kidde adapter KA-F. This makes your replacement a simple install and you don't have to disconnect any wires.
All in all the "hush" button and easy install make this a thumbs up from me.

We remodeled our house 3 years ago. We have 11 of these smoke alarms connected to our ADT alarm system. We have had the fire department out 6 times because of false positives (we are on vacation) and have been awakened well over 15 times because these have false positives.
1) Initially, they went off because they were too close to furnaces outputs. Mild shaking or subtle heat change set them off. We had to move two of them after months of trying to figure out the issue. Worth noting, we had other alarms in the same spot before the remodel without issue (but those weren't hooked to our alarm system).
2) 3 years after purchase the units are just dying. We have already replaced 3 of them. Before they die, you guessed it. Full alarms 3 a.m.
3) One more problem with the alarms is that the batteries die out quickly. We change ours every 5 months on the mark.
4) The MOST annoying problem however is that it is impossible to tell which alarm is dying or out of batteries. Only our ADT panel chirps. To find out if one is dying you have to go under each alarm, wait for a red flash and then count to 40. If it flashes before 40 seconds, you need to replace the battery (or it is a dud alarm). We have 11 of these things. BUT even if you have 5, you don't want to waste the time standing under them counting to 40. These have really a DUMB battery notification system. Terrible.
We are replacing them all soon. We (and our fire department) have had enough. Seriously. Who wants to worry and deal with this stuff. Not me.

I have nine of the little darlings (Kidde i418 - 5 upstairs and 4 on the main floor) and they just love to talk to each other. Usually at 3 inna morning! One goes off, and because they are all interconnected, then they all go off for maybe 10 seconds, and then they stop! Aaaaggghhhh! Those little signal lights - useless! The green flash at sunset in the Pacific Ocean is easier to find than these miserable little lights. So I go up on the ladder (nine foot ceilings so the hush button is as useless as the little signal lights, i mean from those heights you can only reach it from the floor with a framing hammer....not a bad idea, as it turns out) with the air sprayer from my handy dandy computer cleaning kit and about the third detector i blow out a smallish spider. ok, no prob for two months. Now it is mid-morning on a bright sunny day and all the detectors go off (this is one hell of a racket by the way, there are dead persons now running around in my back yard after the last smoke detector event) and on a bright sunny day the useless little signal lights are also invisible rendering so they are redundantly useless, but now I know the trick, out with the ladder, up with the air can and sure enough, schmutz (a smoke detector technical term) comes flying out of the 4th or 5th detector i cleaned. Silence for about 6 weeks. Yet again, more SD noise. This latest event was about midnight. I figured out that the offending Smoke was once again one of the upstairs ones, so i disconnected all of them and have enjoyed silence for months! I suppose i need a smoke detecting system upstairs, but I surely am NOT going to buy one of those crappy Kidde's!! My REM quotient and Heart couldn't take it. By the way, yes i change the batteries every year, and when i have these repeated false alarms, swap out the batteries just in case. This is Kidde's miserable wretched SD, not a maintenance issue.

Living with these things have been a nightmare.
Without fail, every summer at least 1/2 of them need the batteries replaced--even though I am using Lithium batteries.
They always seem to start beeping when the house really cools down, in the middle of the night, and are so loud they wake everyone up.
Squirreling up a ladder at 2am to change a smoke detector battery isn't exactly safe. And if you just take the battery out they keep beeping, even if you UNPLUG them!
They are so loud you have to put them in the car, outside the house, so you can't hear the darn things--it's like living in an episode from some second-rate sitcom.
The problem is as soon as the battery loses even a tiny bit of charge they need to be replaced; the replaced batteries still test 100% good, but they beep in these things.
I've even had to return new lithium batteries to Amazon because they wouldn't work in my smoke detectors.
But that's not where these detectors truly excel: They have a talent for going off for no particular reason (again, always in the middle of the night or even worse early morning--when no one can get back to sleep), sending your kids into a state of panic and terror (remember, when one goes off, they all go off--and good luck finding the culprit).
Sometimes, in the middle of the night, as I tried to stop my kids from crying, while frantically searching for the illusive source of some phantom fire, I actually wondered if my smoke alarms weren't possessed by the spawn of Satin himself.
I've just started ripping them out and replacing these with decent detectors--at least I have a big supply of perfectly good 9-volt batteries for them.
Seriously, these smoke detectors will actually make your home less safe!

I've got a new house full of firex i4618 alarms, hardwired in and interconnected with 3 of their big brothers with CO detection.
All are Beasts from hell. And they ship with carbon-zinc (old style cells) batteries, which on the first chilly days, get low and all start chirping. So, close to $40 to replace all the batteries, then some fool tells me 3 weeks later, "hey bro, DST is ending, be sure to change your alarm batteries".
But the best is the Guests Present sensor. That's the one that goes off 3 hours AFTER the oven is off, and a house full of guests having dessert. Also
has the new clock in it that triggers at 3am, when there is no fire. And I don't think it's spiders crawling thru the units. They are clean. And trying to go from unit to unit, to watch the lights to see which one is triggered, not fun either.
Even pulling into the garage with either car (which passes emissions tests) will set the system off, but at least that helps enforce the kids curfew!
So if you need a nanny or extra shot of adrenaline every now and again (at 3am) these are your choice.
I'm an electronics engineer, and these are clean, and WELL maintained. But the pre-wire in the house (local code) only fits this brand/connector. Three ultra twitchy ones have been replaced in the first 2 months, and hell only breaks loose when the guest sensor activates (nope, no one is sneaking a smoke).

We moved into a house that was built back in 1985. Along with a multitude of other little fixes and updates that needed doing, I noticed that the upstairs smoke detector was looking a little loose on the ceiling. Upon giving it a twist, the bracket broke, and the detector subsequently hung in a jaunty, festive way from just the wires. And I noticed that this was the ORIGINAL smoke detector, dated from 1985. Okay, there's another thing needing replaced.
Installation was a breeze - cut the power, pull the old one, match the correct wires on the harness (white/white, black/black, red/red), screw in the new mounting bracket, plug it in, lock it in place, turn the power back on.
BZZZZZZZZZZZZZZZZZZZZZ / BEEEEEEEEEEEEEEEEEEEEP!
Oops! The 2010 model smoke detector didn't want to play well with the other 1985 smoke detector that I hadn't even noticed downstairs, and they were both going off simultaneously. Okay, swap that one out too, and... blissful silence, and a comforting green light shines from each one.
Trust me: if I could install this, ANYONE can install this. I can't even hammer a nail straight.

You poor, poor souls who rate it 5 stars...I don't know if I pity you because you know not of what is to come, or I envy you because you still sleep in uninterrupted bliss. Of course you are going to rate it a 5 when you purchase it and stick it on the ceiling. Because really, it just hangs there like a trojan horse, along with its friends deployed strategically throughout your house, silently orchestrating their twisted plot to destroy your mental health.
I have 9 of these bastards in my 5 year old house. Religously, I replace the battteries every fall. 2 years ago, I was awoken one night to a "chirp" At least I thought I was. I was groggy. I tried to incorporate the "chirp" into my dream. It worked, for a while. It was faint. It was sporadic. It was...annoying. It was...not working in the dream anymore. So I get out of bed and begin the quest. (At this point I should mention that I am single and have my son half the time, but he sleeps through almost anything...more on that later.) I'm awake enough to realize it's not the alarm in my room. One down. I go to the hallway near the other bedrooms and wait..."chirp". I pivot-like a ninja (think John Belushi in Animal House) and sprint to the downstairs for the next chirp. Once again I'm in position-between 2 detectors, crouched, head slightly cocked, in my underwear, waiting, waiting,,,"chirp"...THERE IT IS!!! But alas, my ears are playing tricks on me! It's coming from somewhere else! I reposition myself, crouch, tilt my head, wait...wait..."chirp"...I'VE GOT IT! I FOUND IT! Now all I have to do is go to the battery drawer and...no batteries...Grrrrr!! No problem. I'll just take the detector down until I get some new batteries, right? You would think so. But guess what? There must be an internal battery that keeps it chirping because that's what it did. I ended up wrapping the little bugger in towels and stuffing it in a distant closet to muffle it. And here's the best part. When I put the new battery in and plugged it back in, it started chirping again! So I took it down and set it on my desk.
Over the next 2 years I've gone through 3 more similar nights like this, although since each time I have fewer detectors remaining, the search for the bad detector takes less time. And they always seem to start chirping in the middle of the night, as if they have some sort of sensor.
But there was one night that was different, and that shortened my life by 20 years. For some reason, on this night, instead of a "chirp", a full out constant alarm sounded, as in every remaining (interconnected) alarm in the house. It was about 4 a.m. I shot straight up, my heart pounding. The sound is ear piercing. It's disorienting. It will actually wake up a teenage boy. In that respect it is truly amazing. I was in a state of panic first of all looking for a real fire. Once I determined that wasn't the case, I then finally found which detector had lost it's mind and pulled its plug.
I now have 4 detectors sitting on my desk while I search for a suitable replacement.
I beg you. I implore you! Please. PLEASE! Don't put yourself through this.

We recently bought a home where these were installed before the purchase.
Within the first week, we had to remove two in the main hallway. We could not cook even the simplest meal without these two alarms going off, and one of them is 30 feet away and around the hallway corner from the stove.
Last night one randomly went off at 4:30 am.
We plan to replace all of them with a better performing brand.
