Customers are dissatisfied with the false alarms. They mention that the product is too sensitive and causes false alarm.

Smoke & Carbon Monoxide Detector

Smoke & Carbon Monoxide Detector
This smoke & carbon monoxide detector stands out for its features and reliability even as a standalone device. The device's capability to provide immediate alerts through loud alarms and a sensitive photoelectric smoke sensor effectively minimize false alarms.But I did hit a slight snag when I was setting it up. Getting the alarm lined up right with the base plate was trickier than I expected. I had to get creative and use a pen to line everything up correctly. It's a workaround, but hey, it did the trick!Also, figuring out how to hook this thing up with smart home systems like Alexa or Ring was a head-scratcher. It might link up quickly, but you need extra stuff, like a base station, to make that happen. So, I just skipped all that and used it on its own. Even though I was initially mixed up about the intelligent features, as a standalone alarm, it's been doing a great job, and I'm happy with it.

I installed this 4 years ago and I love everything about. Install was smooth and easy. It integrates to Alexa/Ring perfectly. I accidentally blew my vape very close to it and it immediately went off. Alarm is extremely loud - loud enough to hear throughout the house. Even so, every Alexa in the house started yelling at me, in case there is a room far enough away that you couldn't hear it. Additionally, I immediately got a phone call from Ring, asking if they should send emergency services.

I don't know that I should even voice my annoyance with an event. All Echo devices go to a 10 volume and the alarm itself is LOUD, so in an accidental activation, I found myself frantically screaming 'ALEXA STOP!!!' but could not be heard over the alarm. I struggled for a few seconds to stop the alarm using the button on the actual device. In the meantime, I answer my ringing phone to tell them not to send 911 but they couldn't hear me until I managed to stop the chaos. To end it all, after I told them "There is no fire", they called my secondary contact to confirm. That would be a nice feature if the alarm on the keypad were pressed by a DV victim, but for my smoke alarm going off, it seemed a bit unnecessary.

Still, 10/10!!!

I run on the HomeSeer home automation system, with the Z-Wave add-on interface. That's a mesh network lets every device communicate with every other in my 3-story house. I had a triplet-package of smoke detectors that talk to each other wirelessly and one of them started eating batteries every month. So I searched on the same ID and this item came up. Ordered it and when it arrived I discovered I can ADD it to my ZWave network, and if it triggers I can have an audio alarm (Zwave, of course) fire off and all the lights in my house come on. How cool. HomeSeer makes it easy to add to the network, and create events of all sorts. I would/will buy this again as need arises.

Set up with ring out of the box in a matter of seconds. Works flawlessly with Ring. My first complaint is having to change batteries every couple of months. May be a tad sensitive to a smoldering wood stove for CO but that is probably a good thing. My bigger complaint is disarming Ring when it's alarming does not silence the smoke detector. So if you are not home and get a CO alarm from your wood stove it will drive your pets crazy until you can get home to manually silence it.

Reviewed in the United States on February 27, 2016
Size: Z-Wave Combo AlarmStyle: AlarmVerified Purchase
I've had this alarm for about a month, and am very pleased. So much so that I purchased a second two weeks after the first. However, before I get to the rest of my comments, I'd like to say something about the nature of reviewing smart devices in February 2016. Right now there are several smart systems, not really a clear front runner, and the ecosystems are rather young. I've seen a number of devices where there were strong correlations between the review given, and the system used. The device didn't change between the two systems, the systems changed. The hubs were different, with different chipsets, with different firmware, with different software, with different setups in different houses. So, just a word of advice that a negative review with System A doesn't necessarily mean there would be a bad experience with System B. Try to make sure your situation will be similar before valuing the review - and take everything with a grain of salt.

With that out of the way, I'd say that this product is designed well. The alarm is loud, and was fairly sensitive to smoke in my testing. When I say "fairly", I would consider that optimal. Very sensitive would be too sensitive, and cause false alarms, and insensitive is useless. I've not been able to test CO2, so no comment there. The first one I purchased has been running about a month, and is down to 92% on the batteries. It is about twenty feet from my SmartThings v2 hub, with only a couple walls in the way. So, I think that is decent battery life. The second one is in line with that battery usage, and is much father away. Pairing was super easy, no problems there. And, one thing I really liked is the rounded-octagon shaped. That made it very easy to screw in or out of the mounting bracket.

I'm not sure if this is SmartThings, or the device, or my software revision, but I was unable to clear the alarm through SmartThings. Seems like that can only be done on the device. But, I don't believe I ever saw anyone specifically mention being able to do this - with any system - so perhaps that is not even an option. But, I could see it as a nice touch. I can hit the button to clear the alarm, because I'm taller, but my wife would have to go get something to step on while it is going off. Having the ability to clear it from SmartThings would be nice for her. But, it's a smoke alarm, hopefully that shouldn't be a common problem, right?

Reviewed in Canada on June 30, 2017
Size: Z-Wave Combo AlarmStyle: AlarmVerified Purchase
Arrived in one day! This unit works great with VeraPlus running the latest firmware as of this time, and is very easy to add to controller. It shows up as two devices - the parent device is a "Smoke & CO Sensor", and a child device also shows up as "CO Sensor". You can create scenes for alerts based on these devices separately, so that you distinguish between CO and Smoke alerts. This unit takes two AA batteries, not a 9V battery which is usually what is expected with smoke alarms. Not that it is very significant, but just more of an FYI. Just a suggestion - don't use Parameter #1 to enable double alerts because if you do, it will make the child CO Sensor device disappear once the controller writes that parameter to the device. Then you can't create scenes for smoke and CO separately.
