Hello Katrina, This unit is battery operated so the green LED will not stay on constantly. That only happens with hardwired units.

Can lithium batteries be used in this device?

Instructions state, "Replace batteries with one of the approved brands: Energizer E91, Gold Peak 15A or Gold Power GLR6A. Warning: Use of different batteries may have a detrimental effect on the Smoke/CO Alarm.

Yes, you will need a drill to tap the anchors and screws that mount the base plate for the unit. However, some times the mounting screws in the old unit you are replacing will match Kidde base plate and no drilling will be required.

It did, but I wasn't sure if the stops on the mount lined up perfectly when it was up on the ceiling so I changed it. The mounting screws are in the same spot so it wasn't a big deal

Great 2 in 1 alarm product for home.
Great product, easy to install with instructions. My home was pre-wired for this alarm in 3 areas but instructions are clear & easy to follow. If unsure, seek an electrician. Safety of your loved ones is worth the price!

Very easy to install. Everything you need is in the box (except for screwdriver). Tested just fine...this is my 2nd one purchased. I install this one in my vacation rental by owner apartment. I like the voice activation. I feel that will provide my (vrbo) guests with an added safety feature. (Sorry for the lead of "elegant". Somehow it got stuck on my review and i could not edit it. I normally dont refer to a detector as elegant)

Great product choice for an older home without the hard wired detectors. I liked that the batteries were AA instead of the common 9 volt and unit was very easy to install with only two screws. This product has added life safety value with the combo smoke and CO alarm.

I don't have a rating for this product. I have just installed it by my furnace, but as of this writing it hasn't went off. When I installed the batteries it sounded like it should work and I liked having two different alarms, one for fire and one for gas leak.
