Smoke/heat detector age

I ordered two 5808W3 smoke/heat detectors through Amazon. I'm trying to figure out when they were manufactured. The four digit number on the detectors is:

1114

Pursuant to doing some research online, that seems to mean the detectors could've been manufactured in 2011. Is there any definitive way to tell? Thank you.

November 2021 week 4.

It certainly is confusing. Those wireless smokes would follow the System Sensor date code.
It could be 2011 or 2021.

I'm not sure they would be selling 10 year old smoke detectors.
2021 sounds too new but that's the date I'd go by.

We'll see if anyone else has an idea.
