The PA20A series B (c. mid 1980s) and PA150 are missing from the list.

I don't know who made that list, but it's incomplete.

It is a list the Federal had in their Service Part Index in the mid 80s so it is a fault that Federal made back then.

Opening an old thread. This list shows the PA20A series 2E first manufactured in 1970. Any idea when the end of the run was? I have a 2E with from Federal Signal, which would suggest a manufacture from 1976 to ?

I was the original poster on FB. I got this supplement with a bunch of vintage books recently.

Here's what I've figured out so far:

Production of the 1E and 2E series may have begun in 1970, but there were also some PA15A series 1Ds and PA20A series 2Ds installed in emergency vehicles that were as new as the 1972 model year.

The PA15A was eventually replaced with the PA150, and production likely ended at the beginning of the 1980s. The last version of the PA20A is the PA20A series B, which was manufactured in the early to mid 1980s. Series B has an optional burglar alarm connection. The circuit board layout is different, but it has the same siren oscillator circuit as the series 2E.
