It was disclosed that a “fire rated armor push plate” was screwed to the surface of both sides of entrance door from kitchen to garage to cover a doggy door hole that was cut into fire rated door. Is this an acceptable fix? There is no label or specs for “fire rating” on plate.
I do not know where you are located or when the home was built. But this is IRC 2018. So, how do you determine if this is a 20 minute door without a listed rating? But I do see the doors must be solid or honeycomb core.
Sounds like a judgement call as you will not likely find official specs for acceptable patching of a fire-rated door. If you are not comfortable making the call you can refer it out to the local fire inspector.
How do you know there was a cut out behind the armor plate and if the door is rated. Was there a rated tag on the door. If there was a tag and if there was in fact a cut out originally, the the rating of the door has been voided.

The hole was disclosed by owner who installed the armor plate? The door was 1 3/4” solid wood so is fire rated. Though I will refer to a fire inspector was just waning to know if anyone on here can confirm this would be acceptable.
Since the label is missing (or not visible) it does not meet the listing requirement. Besides, IMO the integrity of the door was compromised and it is no longer a solid core wood door.
I think we all know that a stainless steel plate is probably OK for a 20 minute door, but it is not up to an HI to approve it.
For more information about protection plates on fire doors, consult NFPA 80, the manufacturers’ listings, or discuss the requirements with the Authority Having Jurisdiction.
