Battery or Hardwire w/Battery Backup?

Other sites, including BRK, show this to be hardwire with 9v backup. Is this correct?
Asked by: baahstun

Will this fit in the same bracket as a brk First Alert, Model no. CO5120BN?

Will this fit in the same bracket as a brk First Alert, Model no. CO5120BN?
Asked by: Marilyn

Why does the caption say battery operated with battery back up?

this doesn't really make a lot of sense. In the short description it specifically says Hardwired with battery backup You need to change the caption or is this the right part? I'm ordering this as a replacement for my existing C05120BN, so I hope the right one comes.

Rated 5 out of 5 by from Ease of use Ordered online and product was available at store on the date promised. Hint: a beep every 60 seconds means the product needs to be replaced.

Rated 4 out of 5 by from CO Monitor This is a replacement unit for one that finally bit the dust. I've got several in my home, and only one failed, after over 10 years. Since they still make the same model, all I had to do it plug it in to the existing frame and wiring. One note: the unit is AC operated (not battery) with battery backup.

Rated 5 out of 5 by from on-line purchase of article not available in store alarm was a replacement for a part that was eight years old, but your website still had it as an option to purchase (no delivery charge if picked up at my store, an option I choose). an employee at the Salem, MA store recommended I go to the website when it was not available. I do not know his name.

Rated 4 out of 5 by from Hope it works I simply replaced the previous unit that kept giving a false alarm after 7 years. I never had a CO2 problem, but I believe it would alarm if we had a real threat.

Rated 5 out of 5 by from Direct Replacement This is a direct replacement for the unit that was installed in our home when it was built. The original unit was 13 years old and beginning to fail. It was an easy replacement.
