Let's be honest - I'd love to provide a comprehensive review
October 27, 2016
Reviewing a smoke alarm is a rather difficult thing.Let's be honest - I'd love to provide a comprehensive review, one that will educate and give people a proper breakdown on just how well the unit works. I can't do that, and I hope I never have the opportunity to give a comprehensive review on just how fast these alarms are able to detect smoke for obvious reasons.I will say, however, that they were packaged nicely and included batteries as well. I sincerely hope that I never hear one of these things unless it's trying to tell me that the batteries are crapping out.
No False Alarms
May 30, 2016
Gone are the false alarms, which were a daily occurrence (almost). Yes, we need a new vent hood. In the meantime, at least this is not irritating the heck out of us like our last one.
No more concern over changing batteries!
April 20, 2015
After reading many professional opinions, I learned that photoelectric smoke detectors are generally safer choices than ionzation models. From what I've read, it seems that photoelectric sensors might be very slightly slower (thirty seconds to a minute) slower at detecting strong flame fires but much, much faster (up to 30 minutes) faster at detecting smoldering fires. To me, this exchange seemed like a no-brainer, so I hopped on line looking for a photoelectric detector with good reviews. I was a bit shocked to find that there aren't many out there. I opted for this one based on its good reviews and low cost, ordering 4 to replace all the detectors in my house.Installing them was easy as pie. To install in drywall, you'll need to press the mounting plate against the ceiling and mark the holes you plan to use with a pencil. Then, using a 1/4" masonry drill bit, drill holes where you marked. Insert the plastic drywall mounts that come with the screws into each hole. Then place the back plate so the holes on the plate match up with the drywall mounts. Simply drive the included screws into the drywall mounts and you're good to go.Note that if you're screwing straight into a stud, you will not need the drywall mounts. You can drill an 1/8" or 1/16" pilot hole to help you drive your screw in straight (use a general purpose bit for this), or, if you're using a drill, you might be comfortable just driving the screw in without a pilot hole. If in doubt, drill a pilot hole first.The battery mechanism on these units is peculiar but quite a nice surprise. This unit uses 9V batteries, and it uses them in a way that axes that infamous snap-on connector. In place of that old style connector, you'll find a slide out tray on the side of the device. The tray fits a 9V battery perfectly. Stick your battery in, slide the tray closed, and bam! You're in business. So much easier than those old things, where I'd sort of prod at them very carefully to avoid accidentally hitting the test button and deafening myself while fiddling with the battery. When it comes time to replace the batteries, just twist the detector off the back plate and hold the thing in your hands as you pop out the compartment, remove the old battery, pop in the new one, and slide the compartment back in. So easy!Each unit includes a standard alkaline 9V (I believe the brand on mine was Eveready, the same company that manufactures Energizer), so you won't need to buy separate batteries. If you're interested in the long battery life offered by lithium batteries, you might consider the SA710LCN, which is the same smoke detector shown here only with lithium batteries included. Alternately, the SA710CN shown here will accept lithium batteries if you purchase them separately, and the thoughtfulness put into this unit's battery compartment has me feeling much less anxious about changing batteries anyway.All four of the units I ordered tested fine when the button was pressed. They are certainly loud enough for our 2,000sqft colonial. Fortunately, I have not yet had the opportunity to do a real-world (burning house) test, but I did set one off by holding a burning wooden wick candle up so the smoke entered the detector. That was probably a bad idea, though, because the detectors really are very loud. It scared me when it went off, and I almost dropped the candle, risking a real fire. Don't try this at home. The successful candle test is especially encouraging because we have received zero false positives in the ~two weeks we've had these buggers up, even with one alarm placed within five feet of a bathroom door.One small concern I have is the effect room ventilation will have on the sensitivity of these detectors. Two of our bedrooms have ceiling fans, and I'm not sure how the circulation of air will impact the effectiveness of the smoke alarms in those bedrooms, since photoelectric sensors are triggered by particulate matter entering the detection mechanism. Fortunately, this isn't a big concern for me because all bedrooms in our house branch off a common hallway, and I feel safer knowing that a fire that would trip our master bedroom smoke detector would probably also trip the hallway detector. And, as I said before, I'm no smoke detector expert. It could be my concerns about air circulation aren't relevant.Still, when installing these in your own home, be cautious of items like ceiling fans or odd ceiling architectures that might prevent the smoke alarm from being exposed to smoke in the event of a fire. This should be a common consideration for all types of smoke alarms. Overall, I am very happy with the design of these smoke detectors. The battery tray is really a big, pleasant surprise for me.
It works-- I trust it with my life, so it'd better, right?
March 21, 2015
I personally trust the brand, and am replacing a pair of old, failed smoke detectors that my landlord installed over a decade ago. The only complaint I would make is that the battery compartment on my two units was NOT marked "+" or "-" requiring me to double-check that I was installing the 9v battery with the polarity correct. (I rectified the oversight with a fine-point magic marker so that in the future I can see which way to insert the battery without taking the unit down off the ceiling.) The directions are comprehensive and it comes with a battery so it's good-to-go right from the package.
Nice Quality for the Price
March 16, 2015
Not sure how much one can say in a review about smoke detector . . . but it's nice quality for the price. Was very to install -- because I was able to use the existing wall bracket. I would say, if you are replacing an old detector, check sizing info to see if you are able to use your old wall/ceiling bracket. That made replacement a breeze.

January 10, 2015
This was to replace the alarm in our kitchen. We have struggled for years with false alarms. Anytime the stove was opened, even toasting toast would set our old one off. This has been a blessing and we have only had it for about a week. Before, I would find the battery compartment open, because our silence button got used so much it broke. That's not safe at all. But now I can have peace of mind, I even checked it to make sure it was functioning, because we have had no false alarms. Thank you!!!

Good price for 2 pack
August 21, 2017
I hope they work, haven't made a sound. Test monthly and they pass. Says to mount at 3ft, but who does that. Looks nuts. Guess my house will have to fill up to alert, but at least I know it will work. Instaaled the second at my MiL house, no complaints!!
so good. It fits in a convenient space
May 14, 2017
The First Alert CO400 came in a timely manner, as always. So far, so good. It fits in a convenient space, and pretty much out of sight, unless you're looking for it. Thankfully, it hasn't gone off. We'll know if there is anything wrong if it does.
Don't risk your family's safety- this Carbon Monoxide detector is easy to install
March 7, 2017
A "must have" for your RV. Don't risk your family's safety- this Carbon Monoxide detector is easy to install. You do know that CO and LP detectors have a limited life span, or you should know this. They expire in 8 to 10 years, and must be rep-laced with new. You can spend much more on a CO detector, but why would you? Combine the low price with PRIME 2-day shipping and it's a win-win.
Just what I needed
March 3, 2017
Just what I needed for safety and to pass my real estate inspection. no need to go to great lengths to install, can hang easily with a string from a hook on wall, or just place on top of cabinet, though more permanent installation instructions are included.
Great detector, working well, needed battery operated and this is perfect
July 13, 2016
Very happy with the function of this detector. Of course, you never hope to hear it go off so I assume since it is quiet and we are all still conscious, the detector is doing its job. The test performed exactly as it should (very loud beep!) And the little light indicator shows it's on. We needed a battery operated detector due to its placement in our hall, and I was very happy it came with the battery too. No complaints!
I trust it with my life
January 22, 2016
When the kids were small, our family nearly died when a faulty heating unit filled our upstairs with carbon monoxide. The only reason we escaped was because odd smells are apt to nauseate me, and I woke up gagging. As soon as I was awake enough to realize what was happening, I was able to throw open the windows, get the kids out of bed and get everyone outside. Since that night, I have never been without a carbon monoxide detector, and this is the one I use. I bought this new one recently because I broke the old one's test button. I trust First Alert and can fully recommend it.

Simple smoke detector that uses a simple replaceable battery.
February 21, 2017
I have installed 4 of these so far, My first couple are the same model without the "B" and look to be the same in every way.The older two have been in operation since 2009 and work as advertised, no false alarms and trigger only when smoke is present.I decided that since those were getting close to EOL I would buy a couple more and install where I didn't have any.So far the new units seem to be working just as the older units, but I have only had them for a mouth or so, but if they are anything like the SA710's without the "B" then I shouldn't have any issues as those have triggered when they were suppose to such as the one close to the kitchen that occasionally is set off when something on the stove has started to burn.I got these due to the simple mounting and they match my older ones and the mounting is the same.They use a standard 9v battery that I change every year with long storage life rechargeable's that I get from Tenergy here on Amazon. They seem to hold up for the year that I cycle them out with freshly charged batteries.As some have mentioned including the manufactures, you need to take note on location of a new install.Make certain it will not be in located near vents/heat/steam or areas that can set off any smoke detector if a area is prone for smoke such as a kitchen. In my case I install mine at corner locations (10in from the corner) on the opposite wall of any outside door, window or vents if all possible.
safety first!!
February 12, 2017
I looked online for this model as that is what I have in my home and I found it here at amazon..had to replace as when I put new battery in one of the old ones it quit chirping but continued to blast alarm every few seconds..button was broken to test/pause..in any case..i have installed the new one, tested it and so far so good! delivery was right on time as stated by the receipt, and it came new and boxed..satisfied so far!
Great smoke alarm!!
August 3, 2015
Great smoke alarm for a very reasonable price. I'm not sure why so many people gave it a one star review because I bought one and have had no problems at all with it. The alarm works great and with the photoelectric technology I haven't had any false alarms yet. The alarm is loud enough to wake you up no matter how hard of a sleeper you are. Found that out testing it by accident while my roommate was asleep. Great fire alarm all around I'd definitely recommend it to anyone looking to replace there old alarms or just adding new ones.
Easy to install and it works.
May 10, 2014
Fortunately, I haven't had an emergency to really test it out, but it seems to work. I placed it on the ceiling in the hall between two bedrooms. Unfortunately, the bathroom is in the middle and the steam when the door is opened after a bath seems to set it off chirping slightly. It only chirps for a couple of minutes, but it was really confusing initially to figure out what was happening.Anyway, it tests well weekly and seems to work, so I'll assume I'm getting my money's worth.
So far, so good
September 11, 2013
We bought this to replace a very old ionization type alarm that stopped functioning properly. There are so many alarms out there that it required some research to decide what to buy. Ideally one wants it to work well and continually (it could save your life, after all) while not being overly expensive. I think this one fits the bill.The big issue these days is whether to buy an ionization type alarm or one with a photoelectric sensor. I opted for the latter. This is why (I'm quoting from an article which cites the professional opinion of the fire chief of Albany, CA):"An ionization alarm contains a tiny amount of radioactive material to set up an ionization chamber that creates an electric current. When the current is disturbed by smoke, the alarm sounds. It costs about $10. A photoelectric alarm, in contrast, contains a small beam of light. When smoke disturbs that beam, the alarm sounds. It costs about $15. The difference has to do with how smoke from different fires moves through the air and what is in that smoke. For example, an overcooked dinner may produce small particles of smoke that waft through the air. The ionization alarm is sensitive to those tiny flecks, prompting false alarms. The photoelectric alarm can tell better when there isn't enough smoke to be a dangerous fire. On the other end of the spectrum is the smoldering fire, which produces bigger particles. Those aren't as easily detected by the ionization alarm until the smolder becomes flames that produce the smaller particles. Virtually all residential homes with smoke alarms have the ionization type, and virtually all commercial buildings have the photoelectric types, according to several studies." This fire chief is obviously trying to get the photoelectric types into many more homes, as he believes they would save many more lives because they alert you to fire much sooner (and aren't constantly giving you false alarms -- alarms that you then ignore, even though one might turn out to be real).From that information, and other sources that confirmed it, I concluded that the best alarms are the photoelectric type. First Alert has a good reputation, as far as I can tell, so I went with one of their alarms. A little light (from the hole you can see on the right side of the alarm) give you the comfort of knowing that it's working. But of course it also has a test button (the alarm is ear-piercingly, painfully loud, as it needs to be -- the more so for our cats' ears!). It easily screws off its base, if you need to get it down (once you've fastened the base to a ceiling or upper wall). It's also much easier to change the battery that it was in our old alarm. The battery compartment is at the top left, and pops up so that the battery can be gotten at easily, and without needing a sharp object to pry it out of its compartment.
No false alarms in kitchen from burning food
May 28, 2013
I haven't had it too long, but I'm pleased so far with this detector. Our rental's previous smoke detectors (ionizing) were constantly going off--every time someone cooked something or took a shower. And somehow the batteries always die at 3 am. Worse than useless, but anyway...This one has yet to produce a false alarm. I took off a star since, for no clear reason, First Alert seems to have changed the mounting bracket pattern from the First Alert ionizing alarm that it replaced. I feel I should have been able to unmount the old one and place the new one into the old bracket.Not really about this product, but I also feel I shouldn't have to pay $3 or $4 more to get a smoke detector that actually works. How about adjustable sensitivity or something for the ionizing variety? Every time I move, I have to replace more of the radioactive buggers and dispose of the old ionizing ones--americium, electronics, plastic and all. Not burning food is not an option since I have an electric stove and no matter how much I clean it, it still sets them off whenever I turn it on.

Very easy to install!
November 8, 2017
I have not yet truly been able to test this system and hope never to have to. It was really easy to install and I really like that it's battery powered rather than wired in (makes it so we can put it anywhere that is most convenient rather than where we have a plug or are willing to drill a hole). So far, very pleased!
I'm glad to have them
April 27, 2017
Hard to review a week after installing, so what I'll say is that the instructions were adequate and I was able to quickly install both units. I'm glad to have them!
Cheap price for invaluable protection
April 19, 2017
Used several of these to upgrade my vacation home to current code - 1 CO detector on each level near every bedroomThey were quick and easy to install and provide added security to my family. Highly recommend.
Very economical comparing with those units with 10-year long-life battery
January 21, 2017
Can't find any CO detector in CA that need battery replacement on annual basis. All CO detectors sold in CA have the 10-year long term battery inside, and they are more expansive than those units sold in Amazon requiring battery replacement.I have some rental units, I prefer installing CO and smog detectors requiring battery replacement. Mainly, I then have a very good excuse for visiting each property at least on annual basis to replace batteries but also conducting property inspection at the same time.This CO offered by Amazon is very economical. Can't tell it works or not, as I haven't heard that it ever gets triggered by itself (not due to testing). And no tenant ever reports such incident also.
Works as described, but NOT setup the same as the CO400 from a few years ago
November 6, 2016
Beware - if you are replacing an older version (2-3 years ago) of this same model, it is NOT the same exterior as the previous CO400 model. The screw holes don't like up in the back and the battery is in a different location (back in the new, front in the old).I'm not sure why First Alert is using the same model number on this newer version if there are so many cosmetic and other changes. Is it that hard to just use a new number??
installation quibbles
February 1, 2016
I just purchased and installed this. My only quibbles are around installation. There's no real template; just a drawing on the instructions, which are an unwieldy size and I didn't want to cut it up. I made my own by running a pencil over the the mounting brackets and then pressing it against a piece of paper. I also found the screw anchors to be quite flimsy; luckily I had others on hand that worked well.

September 11, 2015
After contacting First Alert, I was told this would work with my old First alert bracket. This would avoid drilling and screwing... just pop it into the bracket. This was not the case; I had to remove the old bracket. I specifically bought the same model series for this reason; I could probably have gotten a better smoke alarm if I had known First Alert was going to change the mounting bracket.
You Get What You Pay For
July 31, 2015
I bought and received two of these alarms in July of 2015. The sticker on both of them says 2005 SEPT 26.Apparently, these detectors have been sitting on the shelf FOR TEN YEARS!These are photoelectric detectors and I don't see any disposal or duration warnings, so I will install them BUT I'll also document this purchase very well, in case they end up failing to detect a problem. My advice for you is to pay a little extra for photoelectric alarms, so there is no doubt.(DO NOT buy ionization alarms. They don't work. You may as well be nailing frisbees to your ceiling.)New Photoelectric = GOODNew Ionization = BADOld Photoelectric = ????
So far, so good...
February 13, 2015
The first one I had started giving me a low battery warning, despite having a new battery in it. So far, so good with the replacement. If this one starts doing the same thing, I'm going to try a different brand.
Not totally happy with product
June 30, 2014

The redone mount holes are annoying.
October 5, 2017
These are okay. Mounted them at about eye level as we have 9 foot ceilings in our house. I bought one of these same models a few years ago and these new ones look exactly the same with one exception... the mounting holes on the back side are slightly off from the older (but cosmetically the same model). The redone mount holes are annoying.

Use care when replacing the batteries....
January 30, 2017
My RV came with one of these. When I was trying to change the battery, the flimsy little tab that secures the battery door broke. I had to buy a whole new unit as a replacement, since the damage was irreparable. The tab on the new unit is just as flimsy, so be extra cautious.. You have been forewarned.
Hole placement different from previous models.
January 26, 2016
I bought these to replace the previous model and I'm irritated. The new model's holes are just a little bit further apart than the previous model. So the holes/screws I already have in the wall don't really do any good and new holes need drilled. Not sure why they wouldn't keep these the same from model to model, but hopefully this saves someone the headache.
why do you need a drill to install?
March 18, 2014
it arrived today....relatively small (little bigger then my hand). It takes a 9V battery (included). What DOES frustrate me is that I need to drill into my drywall to install it (two 3/16 holes). Now, CO detectors need to be replaced every 5 years or so (?), so, when this one gets replaced, I'll have two holes in a wall I'll have to patch and paint, that is unless I can find the exact same detector to replace this one. Its just creating work for you.In todays age of adhesives (3M tape for example), I find myself wondering why there isn't a simpler mounting option that isn't as destructive to ones house. Why not have a simple bracket that adheres to the wall w/ double sided tape that the unit slides onto. (putting on wall, not on ceiling).Now, I cannot just put tape on the back of the unit and stick it to the wall as to replace the battery you need to flip open the back of it.

SA710CN started beeping a complaint about battery after only 7 months ...
January 13, 2017
We bought 3 of these First Alert SA710CN Battery Smoke Alarm with Photoelectric Sensor in June 2016, so only 7 months ago.During the last few days, particularly in evening and night while colder temperature (71F inside), one in a downstairs hall has been beeping apparently a low battery warning every 30 seconds. The (supplied, Eveready) 9v battery reads 9.34 volts, should it be good still.We will call BK/ First Alert and see what they have to say.UPDATE - So we called them today. The response was, essentially, to replace the standard 9V Eveready that shipped with the device, with an alkaline as recommended in the manual (which we did not have for reading, until after the purchase); claims that the standard cells lose charge in storage (the 'failed' one is dated with 12/2017 expiration, a year in the future).So WHY do they advertise 'battery included' if they think the included battery is junk,despite the date code?Buyers, be aware that you will need to buy another battery, and it best be a really good one.We did replace, and we're now waiting for the next cold night (and it's never really very cold here in southern California) to see if chirping has ended.

They changed the drill holes and called it the same model
August 30, 2016
I bought several of these a few years ago. After they wore out, I ordered the exact same model as a replacement, but although the new model is the same size, the drill holes are now in a different place so I must now re-drill the holes in all the locations where the originals were hung. With concrete walls, this is no small task. It is NOT the same device, but they used the same model number.
Even worse, the position of the hangers on the back ...
June 7, 2016
Randomly was shipped units that require 9 volt batteries, but we had older models of the same model installed that use AA batteries. Even worse, the position of the hangers on the back of the new ones don't match the older ones. So, one can't just switch them out.
Cheap construction doesnโ€™t give me much confidence
September 6, 2014
Device is compact and the price is right, so those are good aspects. But the test button immediately broke โ€” the plastic piece snapped where it connects to the case. So be careful when pressing the โ€œbuttonโ€ โ€” or opt for a device that has a regular push button that is more durable.
One of the three was defective
August 10, 2014
I bought the three pack of these. One of the three had a defective door, so the little door on the front doesn't close - it just kind of hangs down. The other two work as expected. I wouldn't order this brand again. I actually had to order another one for a rental house and went with another brand that I am much happier with. The frustrating part was that since this purchase was for a three pack, there is no way to return just the one defective item - you are supposed to return the entire lot which I was not able to do (had already installed the other two before noticing that one was damaged/defective).
Not the best quality!
May 23, 2014
The test flap on the top doesn't work. It stays down, and only once when I tested it (pushing down with all of my force!) did I even get a test beep. Since that one time, I've never been able to get it to do a test beep. I HOPE it would work if I'm ever exposed to carbon monoxide -- I use it exclusively for travel when I'm in hotel rooms. Honestly, I wouldn't waste my money on this product again!
Poor design
December 28, 2013
Apparently First Alert is in the process of changing over the units from the 2 AA battery to the 9 volt. I bought this to replace my old unit that gave out after 6 years. The one I got is the 9 volt unit. The battery compartment is poorly designed -- I had to use a utensil handle as a mini crowbar to pry the 9 volt into place. Additionally, the screw holders on the back are wider than the old unit, so I had to drill a new hole. I'm not deducting from the rating for that, but others complained that the template (that I didn't use) that came with the 9 volt unit is apparently from the old AA battery unit where the holes are closer together. Get your act together, First Alert.

so much beeping.
September 19, 2016
bought these before, locally, and they worked just fine. this batch bought on amazon beeped randomly as soon as a battery was inserted (whether it was the battery that came with them or a brand new one). as the biggest concern with these is that beeping without a cause will lead to people pulling the batteries out, this was complete unacceptable and they were returned. look for the sealed/10-year battery ones from the same manufacturer, as those do not seem to have this problem.
REPLACEMENT SMOKE ALARM BROKE AFTER SIX MONTHS
December 19, 2015
We've had this smoke detector for six months. Recently it started beeping like the battery needed to be changed. That was odd because I had just changed the battery when we changed the clocks this fall. I thought that maybe the battery was faulty... nope same thing with new battery. I've put the new battery in and out several times, and looked to see if it was dirty. Everything looks fine, but still beeps. I would've thought that this may be an unfortunate thing that I ended up with a defective smoke detector. First Alert is thought to be a good brand. TRUTH IS that this is actually a replacement smoke detector that we received when the original one we received didn't work at all. So, fist one didn't work, second one worked for six months. I won't waste my money on this brand again.
Don't recommend this
November 16, 2015
loaded it up, lasted about 1 week before it started to lose the battery that came with it. Replaced the battery with a new one, lasted maybe 2-3 weeks before it ate that battery and started beeping. Replaced that battery, same thing. Bad quality with an internal short or something. Other detectors I have easily last a year on the high quality batteries I put in them, but this model drains them very quickly. Apparently the brand is well known but the quality is definitely not worth risking your life or your family over.

When these smoke alarms work, they are great - sleek looking, easy to install, easy to change batteries...WHEN they work. We ordered 3 of these in early 2014, and one was faulty in the first shipment - the alarm would chirp more and more frequently when there was no smoke in the house. Amazon processed a replacement for us and we have gone along for a year without any problems, until last week - when another unit started chirping again. We changed the battery and now you can't shut it off at all - it's blasting away as though it's in the middle of a fire. I will be looking for another brand of smoke alarm and will replace all three - life is too short to be awakened at night by a false smoke alert.
Endless low battery chirp right out of the box
January 17, 2015
I bought three of these. Two work fine, one will not stop the low battery chirp no matter how many new batteries are installed. I will be looking for a better brand. I expect something to work when I buy it new. This fell short. I waited until I painted my dining room ceiling to change out this one so I would have a clean white product to blend with the fresh paint; as my other one was yellowed. I guess I need to purchase another as this one was a piece of junk that I can't even return due to my waiting to use it. Never again will I use First Alert Products. Beware of the odds of it working.
Silence button does not work, false alarms from steam
December 22, 2014
I installed one of these in the hallway outside a bathroom. It has gone off twice, while taking a shower, from the steam going into the hallway. I tried the "Silence" button both times, but the button just plain did nothing. The second time, I held the silence button down longer -- for several seconds, while the alarm was going off over my head. The alarm never went silent. I had to take the battery out, which is precisely what I was trying to avoid by getting a detector with a silence button.

it will start beeping like low battery
September 22, 2017
I have purchased 5 over the last 2 years. First Alert seems to builds in an obsolescence of about 1 yr, it will start beeping like low battery, but guess what, it is not the battery. I bought 2 of these in early 2017 (January & April) to replace 2 of these I got at the local big-box store in early 2016. The new ones are beeping already (see picture with build date). Do not recommend, wont be buying these anymore, will try Kidde brand that have a 5 year warranty. First alert $20/12 months = $1.66 a month, a Kidde $20/60 months = $0.33 a month. FYI, home alarm systems with Fire/CO detectors typically have a 5/10 yr life.
Two of the three alarms gave a malfunction signal. ...

Two of the three alarms gave a malfunction signal. The troubleshooting guide says replace the alarm and if they are under warranty send them to the manufacture. Don't bet your life on this product!
not good

Didn't work when tested. Waited to long to test,now can't return.
Battery seems loose or weak (9v)
April 23, 2016
The battery cover is not easy to open. No light to show power to device. Instruction say each minute it will flash. I had to push the test button several times to get a beep. Maybe I need to install new batteries.
The reason the price is low is because the manufacture date is 10 years old. They won't last 7 years, only got 2 months use!
January 19, 2016
I would have given this good reviews, because it is easy to use and I think would probably work correctly, but after having it only a couple of months one unit already started beeping with the ERR code. That code means end of life. The units say they have a 7 year life after start of use. Well, 2 months is far from 7 years, but I checked the manufacture date and it was made in October of 2006, so Amazon is selling 10 year old detectors. and apparently manufacture date does matter, not just start of use.
Not a good product

It took 6 units (the original and 2 replacement orders) to get 2 working units. A very poor quality unit.
