Siren amplifiers made by WHELEN and SIRENNET.
The models are 295SL and SNSA2 (EPSL1).
The 295SL is a little older and has an older siren sound.
The SNSA2 (EPSL1) is a newer siren sound, but does not have the various tones of the 295SL.
Personally, I prefer the SNSA2. I like the new siren sound.
If you play the two at the same time, it sounds like a dual tone siren.
