Just before we put The Glade on the market I changed out all the smoke detectors to 10-year sealed battery models.

The smoke detectors at The Glade are all ceiling mounted and hard-wired so when I changed them I used the same brand for compatibility.
That is the new standard in Maryland. As a matter of fact Lowes won’t even ship to our address a new smoke detector with old technology.

In the back bedroom only a base is mounted on the wall — all the others at the bay house are wall-mounted as well.
As I walked through our new home on the Chesapeake Bay I noticed 4 potential smoke detectors — I say potential since one was only the base.

Check out the date circled in red.
Also when I took a closer look at the 3 that remained I discovered they were from 2011.

I was hoping the hard-wired units would line up with the connector of the new unit.
As at The Glade I wanted to replace the smoke detectors with the same brand I was removing so the wall bases and hardwired connector would be compatible. At the bay house the units were so out of date that companies had consolidated and changed names, etc. but I matched the shapes and finally came up with 2 hardwired units and 2 battery units that seemed like they might work.

Sealed battery smoke detectors
Not all brands are available at every store so I ordered KIDDE Firex Hardwired Smoke Detectors with Ionization Sensor from Home Depot and 2 First Alert BRK 10-Year Battery-operated Ionization Smoke Detectors Item #5473117, Model #1046857 from Lowes. They were delivered a few days after I ordered them

One of the battery operated units hangs on the first floor above the piano and the other one is in the back bedroom over the garage.
I started with the battery operated models which did not fit the old bases so I took everything down and started again with all new parts. I did, however, reuse the holes from the previous model. These were not difficult install.

The hardwired smoke detector also has a replaceable battery.
Then I moved onto the hardwired units which were more challenging. First I removed the old base and replaced it with the new one.

The hardwired units come with a pigtail that needs to be wired to the house electric.
I would like to say I switched off the power at the circuit breaker panel but the smoke detectors are not marked so I carefully attached the black wire to the black wire, the white wire to the white wire (with Wago wire nuts), and left the red wire unattached since our smoke detectors are not wired together.

Protected again.
I marked the new installation date on each unit as well as the date when they should be changed again — November, 2034. It’ll be here before you know it.
