This is a First Alert SA301B, which was their model for the BRK 3001 after the implementation of Temporal Code 3. This particular unit was manufactured in 2000, and was an alarm I received from @jdlproductions2746. This model lasted until approximately 2004, and was replaced by the model SA302. Then by 2013 was replaced by the SA320 (which is still in production) along with its hardwired counterpart, the 3120B. Later on they came out with the SA3210, which is a 10-year battery powered model, which in 2023 was replaced by the SM310, which is the Precision Detection counterpart.
