The installation was non-sense. Just remove the old wiring harness (from the previous or old detector) and replace with the new one. Replace the mounting plate and install the new detector. Finally remove the battery protection tab, close the battery compartment and press the test button. As simple and quick as that. The battery backup feature is a nice addition tho the detector, so you still has protection during a power outage (you may be using candles to light your house). I bought four. Excellent purchase.
This is a great basic smoke alarm at the right price. Easy installation and looks good. I have had no nuisance alarms. This alarm is interconnected to all the alarms in my house. If one alarm is activated, they all alarm.
Pros: Battery Length, Easy to Use, Great Sound Quality, Loud, Compact, Clear Instructions, Nice Design, Easy Replacement, Easy Installation

Review 4 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
2 of my 6 i-4168 firex alarms failed within one year
PostedNovember 7, 2014
No, I do not recommend this product.
I installed 6 of these firex smoke alarms and two have failed within 1 year. The defective alarms started chirping about every 2 minutes. The batteries were tested good and there was no dust present.

Review 5 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
There is a reason for a "Quick Hush Feature for False Alarms" on these units. I would not recommend this smoke alarm to anyone that likes their sleep. It constantly went off with false alarms. And with them being hard wired together, the whole house rang out when one would go off. After following the directions from the company and from posts of people who complained, I still kept getting them. Although they may be fairly priced, they are not worth the headache.
Cons: too many false alarms

Review 7 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
The old detectors were 11 years old and they kept chirping even after replacing the battery. It turns out that is the "end of life" audible warning. Smoke alarms have to be replaced every 10 years and sometimes sooner.
The i4618 is the "upgraded" replacement for the builder installed smoke detectors. It looks identical to the old ones. The old ones had changed to an ivory color from white. By building code there are 7 detectors in my home (living room, family room, bedrooms and hallways).
Firex was bought out by Kiddie years ago and changed the connector and mount ring. So, I had to replace the mount ring and change the connector...and no more chirping!
Be sure to turn off the AC power before replacing the smoke alarm/detectors.
Depending on how high your ceiling is and tall you are you will need a step stool or ladder, a screw driver, and some wire nuts, just in case.
It was not not a big deal to replace the mount ring and included connector pigtail. Just loosen the screw enough to turn the old ring to the large hole that lets the ring fall over the screw heads. Then pull down the connector, unscrew the wire nuts one at a time and install new connector.
If your detectors are interconnected, connect red wire to the (in most cases) red or third wire. If the detectors are not interconncted, leave the "cap/cover" over red wire. Do not connect red wire to the bare or green wire which is almost always safety ground.
Sometimes DiY'ers to save money (or using some wire they have left over) will use the ground wire as the third wire. Check all the smoke detectors and verify that the bare or green wire is isolated from (not connected to) safety ground before connecting red wire to it.
Connect white wire to neutral (usually white) and black wire to hot (usually black).
Sometimes wire nuts come apart when "unscrewing" them from the wires. It happened this time, but fortunately I have a few wire nuts in my tool box. To take off the inside "heli-coil" off the wire may require a pair of pliers.
If you do not have wire nuts in your tools or stuff purchasing a varity box of wire nuts is a good idea. They are only a couple of bucks and you'll end up spending that on gas going back to the store.
Push back wires into electrical box leaving connector dangling in the middle. Insert new mount ring over screw heads and twist to securing location and tighten screws just until snug. Tighten the screws too much and you will break the mount ring.
Install connector into back of smoke alarm. Place detector on mount ring and twist until detector locks into place.
Remove cardboard battery preserver and close battery compartment door.
That's it, your done with that smoke alarm. Repeat until all alarms have been changed out. And DO NOT FORGET to turn AC POWER BACK ON! Otherwise, back-up battery will have a very short life.
It took about 5 minutes each with my son helping, bring the new detectors and taking away the old ones.
You should not have to change them again for 10 years.
Once a year with the dusting attachment on the vacuum cleaner clean the opening and around the smoke alarm to reduce false alarms and keeping the alarm working properly.
If some "kitchen smoke" gets to the alarm, just use a piece of cardboard to fan fresh air into the smoke detector. This new version has "smart hush". Hold down the button for 3 seconds or so and it silences the alarm for 8 minutes and LED flashes red. I have not had the chance to use the hush feature yet.
A note: the smoke detector come with a carbon 9V batteries, which wil last about 6 months. I purchase 9V alkaline batteries on-line from a place in Brooklyn NY. Alkalines last about a year, that's why I use them...it reminds me to vacuum the smoke alarm when replacing the battery.
If you can afford Lithum, they should last around 5 years. But you will still have to vacuum smoke detector yearly.
This detectors meet the building codes in most areas, but safety experts say you should have a dual ion and photo detector. Ion (this alarm) is good for fast moving smokey fires, where as photo is better for slow or smoldering fires.
I'm a single dad, so I opted to replace alarms with what "meets" code because replaing all 7 alarms with dual detector would cost around $230. I price matched the i4618 and replace all the alarms for under $100.
If you can afford it install the Kiddie PI2020, it installs on the same wires and protects your family to a higher level of safety. The back-up battery installs in the back (lithium might be good choice here).
I can fully recommend the Kiddie Firex i4618. The last ones lasted the full ten years and pretty sure these will last 10 years too.

Review 9 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
I installed six 4618's in my home here in Hawaii. Was easy to do & went in fine ... I thought. Whenever it rains and is cool (i.e. high humidity conditions), they go into nuisance alarm. And because they are all interconnected, they ALL go off (not their fault, lousy code). But the unit that went into "nuisance alarm" is NOT indicated by LED, exacerbating the problem.
I suppose I will pursue the photo-electric variety instead. But buyer beware of use of a 4618 in a humid environment!

Review 16 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
Needs Adaptor not included not sold at Home Depot
PostedNovember 11, 2012
No, I do not recommend this product.
If you want to avoid re-wiring, these need an adaptor to replace an older Firex and other brand existing AC wiring. Yeh, you can re-wire with what they provide. But it is a heck of a lot easier to save the labor and go the adaptor route. BUY A UNIT THAT INCLUDES the ADAPTOR(s) if replacing a worn out unit that has the older style connection. Home Depot does not sell the adaptors alone.
Cons: extra work to use for replacing old ac wired units

Review 17 for Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup
These smoke detectors/alarms were the perfect replacement item for my old alarms. The installation was very basic and as described. If you current alarms are more than 10 years old, you need to get these and they will be just what you need.
Does the job for a great price, although I think it's a little too sensitive in that it goes off every time we overcook something (the device is in the kitchen). But at least once you press the cancel button it remembers that and you don't need to keep pressing it every few minutes.
