Good for gas appliances

I bought two of these for my garage and in my furnace room where we have a gas furnace and they were easy for my husband to install. I like that they have both a smoke alarm and carbon monoxide detector since some of our i bought two of these for my garage and in my furnace room where we have a gas furnace and they were easy for my husband to install.

These 1st Alert Battery-Operated Smoke %26 CO Alarms with Voice are very reliable and the voice activation is an added bonus, as it can send an alert to your phone if smoke or carbon monoxide is detected and the voice activation is sounding even if you aren't home. We have Apple Home Pods and they work very well and in unison with these alarms. Highly recommend !!
