First Alert SMCO410 Z-Wave Smoke and CO Alarm delivers combination smoke and carbon monoxide detection with Z-Wave smart home protocol integration for residential and light commercial life safety monitoring in connected smart home environments — providing First Alert's combination smoke and CO detection capability in the Z-Wave wireless protocol format that integrates with Z-Wave compatible smart home hubs, home automation systems, and alarm monitoring platforms for connected emergency alerting beyond the standalone audible alarm. The First Alert SMCO410 is First Alert's Z-Wave enabled combination smoke and CO alarm: the same combination smoke and CO detection capability as standalone First Alert alarms, extended with Z-Wave radio communication that allows the unit to report its alarm status to a connected Z-Wave hub — enabling smart home notification, remote monitoring integration, and home automation response when smoke or CO is detected. Z-Wave protocol is the smart home communication standard used by SmartThings, Wink, Vera, Hubitat, and many professional security and monitoring systems — the SMCO410's Z-Wave implementation provides integration with the broad ecosystem of Z-Wave compatible smart home platforms without proprietary hub requirements. For households and facilities that have already invested in Z-Wave smart home infrastructure, the SMCO410 adds smoke and CO detection to the Z-Wave device network: alarm events are reported to the hub, which can trigger programmed responses including lights activation, HVAC shutdown, smart lock operations, and notification delivery to mobile devices and monitoring services. Carbon monoxide detection is particularly valuable in connected monitoring contexts: CO is invisible and odorless, and occupants asleep during a CO buildup event may not be awakened by the audible alarm before CO levels cause impairment. Smart home integration that delivers mobile alerts and triggers connected devices provides response pathways beyond the standalone alarm tone for the CO scenario where occupant perception of the threat may be compromised by early CO exposure effects.

Z-Wave Connected Smoke and CO: First Alert SMCO410 for Smart Home Life Safety Integration
Z-Wave is the smart home protocol that has established itself as the standard for professional-grade home automation and security integration: lower frequency RF operation (908.42 MHz in North America) that provides excellent wall penetration and signal range, mesh network topology where each Z-Wave device extends network coverage, and an open standard supported by hundreds of manufacturers and thousands of certified devices. For households that have built Z-Wave smart home infrastructure — SmartThings hub, Hubitat, Vera, or a professional security system with Z-Wave support — the SMCO410 adds combination smoke and CO detection to the Z-Wave device network without requiring a separate proprietary detection hub. In the Z-Wave ecosystem, the SMCO410 is a sensor node: when smoke or CO is detected, it reports the event to the hub. The hub's automation engine can then execute any programmed response — activating smart lights to illuminate evacuation paths, sending push notifications to mobile devices, unlocking smart locks for emergency services access, or shutting down HVAC systems to prevent smoke circulation. These automation responses are defined in the hub's rule engine by the user, giving the SMCO410 connected capabilities that extend far beyond the standalone audible alarm. For professional monitoring integration, Z-Wave hubs connected to alarm monitoring services can forward SMCO410 events to professional monitoring dispatch — providing the connected life safety monitoring that commercial installations have long offered, available to residential Z-Wave users. First Alert's SMCO410 combines the brand's residential fire and CO detection expertise with Z-Wave connectivity, delivering combination detection capability that integrates with the user's existing Z-Wave smart home investment rather than requiring a separate proprietary connected smoke alarm ecosystem.

Frequently Asked Questions
What Z-Wave hubs are compatible with the SMCO410?
The SMCO410 is a Z-Wave certified device compatible with any Z-Wave hub that supports the Z-Wave Alarm command class. Popular compatible hubs include SmartThings, Hubitat Elevation, Vera Plus/Edge, Wink Hub, and many professional security panels with Z-Wave modules. The Z-Wave Alliance's open standard ensures interoperability between certified Z-Wave devices and certified hubs. Check Ring's current product compatibility documentation and your hub manufacturer's compatible device list for SMCO410 certification confirmation with your specific hub model and firmware version.
Does the SMCO410 require the Z-Wave hub to be active to alarm?
No — the SMCO410 functions as a standalone smoke and CO alarm regardless of hub connectivity. It will sound its audible alarm when smoke or CO is detected whether or not the Z-Wave hub is online and communicating. The Z-Wave connectivity adds notification and automation capabilities on top of the standalone alarm function; hub connectivity is required for smart home notifications and automations, but the life safety audible alarm operates independently of hub status.
How is the SMCO410 included in a Z-Wave network?
Z-Wave device inclusion (pairing) requires putting the Z-Wave hub in inclusion mode and then triggering the inclusion sequence on the SMCO410 — typically by pressing the device's test/programming button per the inclusion instructions. The specific inclusion procedure is documented in the SMCO410 installation manual. Once included, the device appears in the hub's device list as a Z-Wave Alarm sensor, with smoke and CO alert reporting configured through the hub's device settings or rule engine.
Can the SMCO410 trigger smart home automations when it alarms?
Yes — once included in a Z-Wave network, the SMCO410 reports alarm events to the hub. Z-Wave hubs with rule engines or automation builders (SmartThings Routines, Hubitat Rule Machine, Vera Scenes) can trigger any programmed response when the SMCO410 reports a smoke or CO alarm event. Typical automations include turning on all lights, sending push notifications to mobile devices, unlocking smart door locks, activating smart sirens, and shutting down smart thermostats to stop HVAC circulation. The specific automation capabilities depend on your hub's rule engine and connected devices.
Does the SMCO410 work with Apple HomeKit or Amazon Alexa directly?
Z-Wave devices communicate through a Z-Wave hub — they don't connect directly to Apple HomeKit, Amazon Alexa, or Google Home without a hub that bridges Z-Wave to those platforms. Some Z-Wave hubs (SmartThings, Hubitat with the HomeKit Bridge app) can bridge Z-Wave device events to HomeKit, Alexa, or Google Home, potentially making SMCO410 events accessible in those voice assistant ecosystems through the hub. Direct native integration with voice assistant platforms requires the hub to support that bridging functionality.
What is the power source for the SMCO410?
Consult the current SMCO410 product documentation for its specific power source configuration — Z-Wave smoke and CO alarms are available in battery-powered and hardwired configurations. Battery-powered units offer simpler installation without electrical wiring; hardwired units with battery backup are typically required for new construction under current building codes. The power source affects installation requirements, battery replacement schedules, and interconnect capability with other hardwired alarms in the home.

It is compatible with Ring Alarm.
Works fine with Ring base station, but initially when I tried to "add device" and then scan the QR code, the app couldn't find it, and the only smoke detector I could select was the Kidde one. But if, instead of scanning right away, you select one of the "other options" at the bottom of the screen, it is listed there and you can scan and connect.Glad to have the 10 year battery life AND z wave compatibility! This replaced previous generation device that stopped working after about 3 years years, but to be fair, it was located in my garage in New England, so it endured extreme temperatures. I was happy that this one fit into the existing mounting bracket.

A downgrade from the model this unit replaced
This would be fine if this worked as advertised. It states that this is a Z-wave connected device. My Z-wave hub (Smartthings) can see it as a Z-wave device. However, it would not connect properly to the hub. When the device made a connection where the Smartthings app required the PIN (basically the first 6 numbers of a long string of numbers on the device used to connect it to a hub), the process would hang and not do anything and the app would hang until you closed the app. No matter how long I waited for the process to finish, the device never would show up in the app.Other times when I try to connect the device to the hub, it would connect but "insecurely." While there may be some reason to be alarmed (pun not intended) by the wording, it also meant that not all functionality worked. Not that there is a whole lot of functionality, but it would just show up as a Z-wave sensor. When I opened the device status in the app, the app would briefly pop up a warning that the device isn't reporting all status. It had various statuses in the app that presumably would never report anything (eg humidity). Obviously, I would not expect the device to ever report many of the different statuses, many of which were not relevant. And while I could have assumed the smoke and CO2 sensors would function properly when the device is connected "insecurely," however I was not going to assume that. I could also assume this would still function like a standard smoke/CO2 detector, but why pay extra when non-smart detectors cost so much less?Because I could not get this device to connect properly, I have returned it and bought a standard smoke/CO2 detector. I am replacing an old one that was in a little used room, so I can get a "dumb" detector for that room. In the future, I probably won't buy any more "smart" smoke/CO2 detectors. There are "smart" "alarm listeners" that probably aren't as informative than having the devices reporting status directly, but if a alarm is sounding the smart (pun intended) thing to do is evacuate and then assess the situation. Standard alarms are enough. Sure, it would be nice to be alerted of rising CO2 levels before evacuation is necessary, but hopefully the alarm never needs to sound anyways.

Only lasts 10years then you have to replace it
Works OK. Paired easily to HomeAssistant with a ZWave adapter. Like the fact that it won't do the end of life chirp and battery will last 10years (life of the detector). I can't hear the stupid end of life chirp and it drives my poor dog nuts. Took me a while to find the culprit and my dog was shaking for over a day afterwards.

Z-Wave Verification Failure
The FirstAlert Model SMC0410 will not connect to my Z-Wave Hub. It communicates initially and the Hub recognizes the device and the app swithes to the "Verify Your Device" page to enter the 5 digit code, it already had the subsequent 35 values. After entering the code, the "processing" rotating circle appeared. After re-initiating the the FirstAlert by holding the button for 2 seconds, it flashes green for a couple of seconds, the app keeps spinning, verification never completes and it eventually failed with the 34-501 code. The subsequent Exclusion worked, indicating that the Hub and FirstAlert were indeed communicating, but the Verification Process does not work. I do not recommend spending extra for this z-wave version of this fire alarm.

Good product. Confusing setup - here's the answer.
I'm using this with a Ring Alarm system. I had an old detector that I was replacing with this one. Remove the old one in the Ring app first.I had a hard time getting this one to pair with my Ring app. I would start the device add and it would stop before the detector was paired. It would tell me to add the device to it's base and push the test button. This would result in multiple alarm rings right in my ears (my ears are still ringing). Here are 2 things to try if you are struggling with adding this device to your ring devices. The second one (resetting the device to factory settings) fixed my issue. I did this reset (holding the test button for 15-30 secs) and then was able to add the device to my Ring system.1. Perform a "Z-Wave Exclusion" (Crucial Step)Even if the device is new, it may have residual data from factory testing that prevents it from pairing.Open the Ring App, go to the Menu, tap Devices, tap Alarm Base Station, and tap Base Station.Tap Advanced Options, then tap Z-Wave.Tap Remove Z-Wave Device. The app will say "Listening for a device...".On the SMCO410, press and hold the test button while you slide it into the mounting bracket (or insert batteries while holding the button).The app should indicate that a device was removed.Ring CommunityRing Community+42. Factory Reset the SMCO410If exclusion did not work, factory reset the detector:With the batteries installed, press and hold the test button for 15–30 seconds.Release the button after the green LED blinks three times and you hear 3 chirps.Wait a few seconds for it to enter standby mode before trying to add it again.

Works with Homeseer, fits existing base on ceiling
Install was easy for me, including the zwave setup on my Homeseer system. VERY IMPORTANT: The device is turned on by the base, mine had 3 clicks. You know it is turned on when the smoke detector chirps. Once it is turned on, it can not be turned off, and, it is an perfect fit for the older first alert zwave smoke alarm base that is already mounted to my ceiling. So replacement of the old alarm was super easy. I put this one in my kitchen because it advertises less nuisance alarms and the old alarm sounded every time I cooked a pizza, so far this hasn't had a false alarm with a pizza cooking, so it does seem more accurate, but we haven't had it long.This connects with zwave mesh. When it first turns on it automatically starts hunting for a hub. So the process of connecting it to my hub was: 1) Get the zwave 40 digit code into my hub, check it 3 or 4 times to make sure it is accurate. 2) Get Homeseer to start searching for a new Zwave mesh (not long range) device. 3) Connect the alarm to the base (keep turning until the alarm chirps). 4) Wait, keep waiting, be patient, and it connected first try.This alarm has better reporting to the hub then the old zwave first alert which never really worked well for me. Zwave setup instructions that came with the device are not very good and the website listed in the instructions just kept redirecting me back to the first alert main website. Other then that I am very happy with this alarm.

Read the instructions, detector must be attached to base to set up
Update: operator error. The detector has to be attached to the mounting plate. I should have read the instruction better. All units work great!!Ordered two units. First one worked great. Paired well with ring. Second one was dead and after further inspection it looks like an older unit as the LEDs are not marked. It’s a shame is it’s a great value with both smoke and carbon monoxide plus ring integration. I’m concerned about battery life but it has a 10 year warranty so hopefully the can be replaced.

More false alarms, can't pull or replace batteries, so they charge you more
This is my frist and last of the new SMCO410. It false positives much more easily than the older model, and worse - the silence only lasts 60 seconds not 10 minutes like on the old. AND they jacked up the price (after discontinuing the cheaper model, of course).I just lived through an ordeal where it went off in the middle of the night, and I had to get up dozens of times for 3 hours to silence it. I tried blowing it, moving it to another room, putting it NEXT to the older First Alert Z-Wave (that still works and wasn't triggering). The thing was gaslighting me. Because it was outside of Support's hours, my only recourse was to either SMASH IT, or put it in a blanket, inside a box, in a another box, in the trunk of my car... and I could STILL hear it.I had previously been running the older Z-Wave model that integrated with Ring but had lower sensitivity (still triggered when we burned toast though). I didn't have to run compressed air on the old one every 30 days. This new one triggers when a tree blows in the wind. I am so angry.I guess I will need to get a dumb non-Ring model now, since First Alert wants to lock us into products with short lifecycles and a proclivity to false positive. I'm not sure it'll even last the 10 years given how many times it has alarmed. Do not recommend.

It IS SmartThings Compatible... but... it's not easy...
Out of the box, this smoke alarm would NOT connect to SmartThings, no matter what I tried. The instructions are a joke so it took searching and trying... so here's the process:1. You have to put the alarm on it's mount. Note that the mount has changed from the previous battery version, so plan ahead.2. You have to run Z-Wave Exclude first, and put the detector into inclusion mode to get it to reset. ***Putting it into INCLUSION requires holding the test button until there are TWO beeps. Not one, not three... TWO beeps.*** You will know it's in inclusion mode because the green lights flash quickly a few times.3. After doing an exclusion, add the device via it's QR code. You'll need to put the alarm back into INCLUSION mode again now.After figuring that out and jumping around on one leg chanting to the smarthome gods, this Smoke Detector was fully connected and identified as a smoke detector in SmartThings.I took stars away because the instructions are awful and because I had to get ladder to swap out the mounting ring. WHY did they change this!?!?!?!The description is nice.

Ordered two. One arrived defective
Ordered two of these. The first one synced to my hubitat C8-Pro hub perfectly. The second one would not sync after 30 minutes of tying after factory resetting it like ten times. In addition, the second one started doing the 3 chirps which indicates a faulty unit.Called the support number. After a couple questions and the fact they could hear the 3 chirps over the phone, they are sending me a new unit in the mail and they are paying shipping. Just have to wait for it to arrive.Edit: New unit arrived in the mail and it synced right up to my hubitat. So I received a faulty unit which First Alert resolved for me for free with a new unit shipped to my door.
