Amazon is offering the First Alert Z-Wave Smoke + Carbon Monoxide Alarm for $35.97 shipped. That’s 30% off the typical rate there and is the best price we’ve seen in over six months. Since these work with Z-Wave, you’ll be able to use a compatible hub or something like a Ring Security System to group alarms together. I recently bought a few combination detectors and this deal has me kicking myself because I could have spent just a tick more to have Z-Wave compatibility. Rated 4/5 stars.
Considering that the combination detectors above are powered by two AA batteries, it’d probably be a good time to apply your savings towards an AmazonBasics Battery Charger for $15. Charging AA or AAA batteries take just four hours and it even has a built-in USB port so your outlet can still be used to power or charge other devices.
First Alert Z-Wave Combination Alarm features:
- Help keep your family safe with this battery-operated smoke and carbon monoxide combination alarm. This easy-to-install smoke and carbon monoxide combination alarm connects with other Z-Wave compatible alarms and a Z-Wave hub (sold separately)
- Certified for use with Nexia Home Intelligence, Ring Home Security System, and other third party Z-Wave systems; not compatible with WINK or Onelink
