I'm curious: how loud are the Federal Signal PA15A/PA20A Series E electronic sirens (also including variants such as PA150/PA200, etc)? I'm particularly interested in how loud they are with 58-watt speakers vs. 100-watt speakers.
Sorry, I should've been clearer. I meant how loud are they. For example, it's said that the Q series mechanical sirens put out 123 decibels at 10 feet, so that's what I'm looking for for these sirens.
