Trusted brand and great integration with ring alarm system.
First alert has always been one of the “gold standard” products for smoke and carbon monoxide detection. This version has two great features which make it a winter. The first is a 10-year sealed battery. Eliminates the need for changing the batteries with every time change. The second is Z–wave certification with easy integration with ring alarms base station. Each of the three I purchased easily was found and integrated into my ring alarm base station. In this way, not only does the alarm ring in the house when it senses Smoker carbon monoxide, and alerts me on my app so if no one is home I can call the fire department. Also, if you pay for ring professional monitoring, then the ring people will call the fire department. These are great detectors with great functionality. Highly recommended.

Peace of Mind – Seamlessly Integrated
I couldn’t be happier with this smoke and CO alarm. Setup was incredibly easy—within minutes it was paired with my home automation system (hubitat). I love the fact that it’s battery powered, so I didn’t have to worry about wiring or placement limitations.The alerts are fast and reliable, both on the device and via my hubitat app, which is a game changer when I’m away from home. It’s reassuring to know I’ll be notified instantly if something’s wrong. The dual functionality (smoke + CO detection) in one compact unit is super convenient too.The build quality feels solid, and it even has a sleek, modern design that blends well with my home decor. Highly recommend for anyone looking to boost their home safety and take advantage of smart home features. Worth every penny!

Smart Protection & Peace of Mind for My Home
The **First Alert Battery Powered Z-Wave Smoke Detector & Carbon Monoxide Alarm** has been an excellent addition to my smart home setup. It integrates seamlessly with my Z-Wave system, allowing me to receive real-time alerts on my phone whenever smoke or CO levels are detected. The installation was super easy — no wiring, just pop in the batteries and mount it on the ceiling.One of my favorite features is the dual protection for both smoke and carbon monoxide, which gives me peace of mind knowing my family is protected. The battery-powered design makes it versatile to install anywhere without worrying about electrical connections. The battery life has also been impressive so far!This alarm has already integrated smoothly with my smart home hub and has been reliable without any false alarms. I love how I can check the status remotely and even get notifications when the battery is running low. For anyone looking for a reliable, smart-enabled smoke and CO detector, this is an excellent choice!

Frequent False Alarms + No Way to Reconnect to Ring After Reset
As a professional installer and Ring Authorized Reseller, I’ve now seen two cases where this First Alert Z-Wave Smoke & CO Alarm (ZCOMBO-G) triggered false alarms for no reason — one in the middle of the night.Worse, after doing a full factory reset to try and fix the issue, the Ring app kept saying the device needed to be reset, even though it already was. This made it impossible to re-add to the Ring Alarm system.Ring support recommends using their Smoke & CO Listener now, which listens for the alarm sound rather than pairing directly — and that seems to be the only reliable workaround since this model is discontinued and unavailable everywhere.Great idea in theory, but this product is now outdated and problematic. Recommend switching to standard detectors + Ring Listener until a better Z-Wave model is available.

They’re okay
The good – the batteries lasted nearly a year and a half.Seems one of mine is defective. I thought it had alarmed to let me know to change its batteries, but, then with fresh batteries 5 hours later it decided it was going off again. So hopefully a warranty replacement is simple. 🙂

Works with ringing system
Works with the ring system. we did have one out of four that we ordered Give a false alarm . Fire department came because we weren’t home. There was no fire. It did the false alarm twice more. contacted the manufacturer and they sent us a replacement. No issues since.

High quality and easy to install.
It was time to replace all of the units in the house. The old ones were 10 years old and expired. I bought 14 of these and replaced all of them in less than 20 minutes. Getting the ladder and moving it to each room took more time than replacing each unit. Twist, unplug…… plug in new one, pull battery tab and twist into place….. Done.

Works with SmartThings
Easy set up on my SmartThings hub. I was a total dumb dumb with the batteries on the first one I ordered. The batteries need to be installed in the opposite direction. Looks just like the one I bought back in 2017 except the logo on the front.The siren is very loud especially if you’re holding it. The green LED does not seem to be very obtrusive, however, I’d probably still cover it with a light filtering sticker.

Es capilla de configurar, lo tengo agregado a un hub smartthings. Me suena con cualquier anomalía en el aire. Lo mejor es que si no estoy en casa me avisa en smartthings si se detecto algo.

Al parecer si es el producto ordenado, solo difere del diseño exterior de la carcasa

Compré 4 detectores de monóxido de carbono y en menos de un año solo funciona 1. Me aparece un mensaje de que los aparatos necesitan un factory reset y no se conectan a mi ring app. Intenté hacer el factory reset y siguen sin funcionar.
