Answer: 
It comes with its own mounting plate so I THINK you can use it. I replaced all of mine at the same time.

Rated 4.3 out of 5 by 84 reviewers.
Rated 4.0 out of 5.0 by Easy to install, but had to make another trip to Home Depot I had to replace battery operated smoke detectors with interconnected hardwired smoke detectors with battery back-ups in order to pass inspection for a rental. I was surprised to see that they did not come with screws to attach to the junction boxes! There were no wire caps either. This meant ANOTHER trip to Home Depot and lost time. The frustration factor is why I gave it 4 stars instead of 5. May 15, 2016
Rated 4.0 out of 5.0 by smoke detecor simple replacement of existing units 18 years old! April 27, 2016
Rated 1.0 out of 5.0 by poor design choices This smoke detector is supposed to be a replacement to the ADC 120-1072B. The base is different and the wiring. This detector is also ionization type so it is not good in a kitchen as everything sets it off, for a kitchen you need model P12040, again this model does not use the same base as the product on this page, the i5000 model i4618a. It makes you wonder if Kidde just couldn't get the design right, did they do it on purpose, just a screw up, I have no idea how the product will hold up if they cannot even get the base and connectors right. Ohh and the first one had a broken interconnect so it would not tell the other units it was in alarm, I threw it out in disgust. February 23, 2016
Rated 1.0 out of 5.0 by horrible installation i went to replace exact item with this new one after ten years. They changed the connector to a triangle shape from a 3 pin horizontal shape. Have to rewire everything April 19, 2016
Rated 5.0 out of 5.0 by Tremendous savings on the 4 pack Went to buy 4 to replace all units in my villa. The 4 pack for $50 vs $17 each is a no brainier. Easy to replace, just make sure to kill the power at the breaker panel. April 6, 2016
Rated 5.0 out of 5.0 by Better safe then sorry The current alarms were out of date and this purchase filled the bill for being safe and sound. March 29, 2016
Rated 5.0 out of 5.0 by Great deal buying contractor 4 pack! Easy to install. Save at least $2 per alarm buying the 4 pack! April 2, 2016
Rated 5.0 out of 5.0 by Replace These every 10 Years These were the same brand that came with our new house ten years ago. I replaced all 7 0f them and 3 carbon monoxide alarms in about 2 1/2 hours. March 8, 2016
