Customer Reviews

Faulty unit replaced quickly by manufacturer I've had two of these detectors working well for 6 years and one finally hit end-of-life and required me to replace it. I purchased two of the same SKU, but they don't say "OneLink" on the face of the unit. When trying to interconnect the two units as I had before, I've had no luck. At step 4 of the instructions, the 1st unit (already set up) doesn't cause the green light to go out on the first unit as described. It simply goes into test mode with no effect on the 2nd unit. The 2nd unit can be setup and works on its own. I have two apparently functioning CO and Smoke detectors working but with no communication between them, which is why I purchased them. I have the two units inches apart, so distance isn't the problem. I've tried linking in the opposite direction with no difference in behavior. I don't know if I have defective units or not. And if only one is defective, I can't tell which one. I contacted BRKElectronics (which makes the device now) and they verified that at least one of the devices is defective and are sending me two replacements. I'll update this once I've received the replacements. Two replacement units arrived in a few days and work perfectly. I'm updating my rating because of the excellent customer service. 5Does not last; First Alert does not honor warranty All of our units started chirping three times and indicating an "error". I called First Alert to use my 7 year warranty and they said the warranty is only 5 years and would do nothing for me. We spent almost $800 on several of these for our home and I am very disappointed in the lifespan and First Alert's poor customer service in not honoring the warranty. 1Works as advertised, and since networked, it's REALLY nice that it speaks the location so you don't have to run around guessing. Once set up, these are great because of the wireless feature....you WILL hear these detectors everywhere you've put them (I have FOUR), so your response time won't depend on distance nor soundness of sleep. The instructions for 'linking' them are correct, but read and re-read carefully, since it is easy to make a mistake, and you start over (not a big deal, once you learn it, takes less than a minute). I've had 2 smoke only detectors that don't 'speak' for a couple years, and I easily get a year out of the batteries. I expect these CO & smoke units to be as good. We'll see. With some testing, they really do work well, and with four interconnected....there WILL be a LOT of noise in your house...which is what you want. Great way to update the safety of an older house, with no wiring required. 5These detectors are a MUST HAVE. These detectors are great!I originally purchased some of these wireless interconnected detectors for one of our vacation rental properties because the licensing authority required interconnected detectors in each bedroom (these are usually hard-wired), as well as in all the main areas of the house. They worked so well that I have since installed them in each of our homes as well as in my parents and my grown children's homes.Pros (+) and Cons (-):(+) - They very easy to install (I recommend self-tapping drywall screws and forget about drilling and the plastic toggles and screws that come with each unit - hold the base on the ceiling, insert 2 drywall screws, snap the unit onto the base and you're done - 2 minutes at most).(+) - They are really easy to program. I do it a little differently from the instructions - when I put the batteries in the unit before I put it up I push the test button when the unit initializes and then select the room location. Then when I snap the unit onto the base I open and close the battery drawer while holding the test button, the green light flashes and I go to the next nearest detector and push its test button and voila, the new detector is now on the wireless network and goes into its test mode in the room where I installed it. Very quick and easy!(+) - They are really loud, and when one goes off they all do, each one reporting the location of the originating alarm ("Fire in Child's Bedroom" for example, or "CO2 level in Kitchen is xxx parts per million - Evacuate!" when you have a combo smoke and CO2 detector).(-) - It would be nice if they provided a location recording function so you could program additional locations with your own voice because the detectors come with a finite set of locations that you can use. For example, there is no "garage" location to choose from, or "upstairs" and "downstairs" locations that might be duplicates (like hallways, bedrooms, etc.). There's only one "Child's" or "Guest" bedroom locations to choose from so it would be nice to be able to program each child's room with their name, so you could say: "Nancy's Room" or "Teddy's Room". As it is now, if you have 3 kids' bedrooms, each one would say "Fire in Child's Bedroom" and you would not know which child's or if it was upstairs or downstairs. Nonetheless, this is 100% better than just having one detector in each hallway and not knowing where the fire was concentrated at all.Bottom line... I recommend that you get one of these for every room in your house. It will be expensive, but shy of getting a complete central alarm system, it will be the best piece of mind that your dollar can buy for you and your family's home safety. 5SA511's link up with SCO500B no problem Smoke detector links with SCO500Bs (Smoke/CO) no problem. I got 4 of these (one for each bedroom on the same floor) to comply with the city building codes in southern California in 2016, after an upgrade to some non-related parts of the house. In addition I got 2 smoke/CO alarms (SCO500B) upstairs/downstairs hallways. The units I obtained were on the California Fire Marshal's list of approved devices. These don't have the 10 year battery - a requirement that can be waived if multiple units communicate with each other and report faults and weak batteries, etc. I sent a list of devices and planned locations to my local building inspector before I bought these - he said OK and they were installed and inspected. After programming the locations for the announcements, we hung them in their respective rooms. While some other construction was going on (flooring), we put dust booties over them to keep the sensitive detectors form collecting dust. These may need vacuuming periodically - so far in 3 months no false alarms.One trick in getting all these programmed - I got a room-full of pillows and covered each one with a pillow (in the same room) when programming the cross-communication - kept the noise level down when I set up a house full of devices. 4Have had many fail, unreliable, don't buy as a new system If you're buying these for the first time, don't.I have several throughout my house and keep making the mistake of replacing defective ones. After buying 3 so far I should have just paid $300 or $400 to just buy a new system altogether.These have many false alarms for apparently no reason. I am not talking about steam from showers or other common causes. Rather, I have woken up at 2 am with sirens for no reason.Amazon brand AA batteries also caused additional problems in multiple units, until I switched them back to Duracell. 2Kids wouldn't wake up to our old alarms. After learning that standard smoke alarms don't perform well at waking kids, we began experimenting... Kids didn't move at all with our old "standard" smoke alarm. Very surprised, I bought one of these voice type to try. First off, the beeping sound is quite a bit different from our old alarms, and the added voice is a nice feature. After trying the old alarm again with no movement, we then tried the new alarm. They didn't wake up right away, but after about 10 seconds, they started to move around and open their eyes. We bought five more to add around the house. You can't put a price on safety... If you haven't tried waking your children with your existing alarms, you should. You might be very surprised at what you see (or don't see). 5False alarms Twice since we bought it a couple of months ago, it's triggered false alarms in the middle of the night. So what can I do in those moments, but take it down, pull the batteries, and go back to bed? I'm not sure if i can get my money back at this point, but I'm going to try. 1Great multi-location detectors I am a volunteer firefighter and I highly recommend these detectors. They interact with each other wirelessly so if one alerts they all begin to sound and tell you which room has an alarm. I currently have four installed on three floors of my house with one being a smoke/carbon monoxide combo. When installing you easily select the name of the room it is going into from the pre-programmed list. If one of the detector activates they all verbally tells you which room it is. They also tells you which room has a low battery. I did have to replace the CO detector after about five years but that is normal for CO detectors as they expire. 5False alarms, wireless interconnection doesn't work These were fine for about 6 weeks. Set them up so they were interconnected and would tell you which one was alarming. "Test weekly, clean monthly" OK, we'll do that.Then they false-alarm in the middle of the night. Alarm came from another room, but the "talking" part didn't happen. OK, that was weird, but maybe just a one-time thing. Now, about a month after that, they have false-alarmed four times in three days. None of the times did talking wireless feature work. You hear one start going off and then they're all going off.I can not recommend these. Not at all. Find some with better ratings. Sure you want to be safe, but you don't want your safety devices to drive you insane, either. 1
