The Whelen WPS 2800 Series were similar to the Whelen WPS 2900. Except these were a evolution to the WPS 2700 Series and it's kinda older.
Some of these were installed in SoCal. Ranging From San Onofre To San Juan. When SONGS (San Onofre Nuclear generating Station) Stop Testing These! They Were Disconnected And Torn Down. Duderocks5539 actually got one of the 2806 and not the 2810 as it was too large to fit.
Most of SONGS Whelens are removed. The rest in the US are the same. One in Illinois has a glitch.
