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

Rated 4.4 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by 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. March 1, 2016
Rated 4.0 out of 5.0 by 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. December 8, 2015
Rated 5.0 out of 5.0 by CARBON MONOXIDE ALARM Prompt shipping and easy to assemble, I would recommend this product to my friend. January 6, 2015
Rated 4.0 out of 5.0 by 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. October 22, 2014
Rated 5.0 out of 5.0 by Carbon monoxide We love this product. We would recommend this product to my family and my friends October 15, 2014
Rated 5.0 out of 5.0 by 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. March 24, 2014
Rated 3.0 out of 5.0 by Good product, but difficult to connect to mount This is a good product except that it is very difficult to connect to its mounting plate. I screw it in and then I notice it hanging by it's wire sometime later. November 12, 2013
