for the 1st time in over a year, all 5 of our sirens sounded for this month's test last Saturday. I was too tired ot actually go to one of the sirens, do to working 3rd shift on Friday night, so there's not much to see, but plenty to hear. Also I had to edit out the siren and cancel tones per OEM's request.
What you'll hear is, the test announcment going over my scanner, and the 1050hz pre-voice tone and the tail end of the test message over our 2 WS 2008s. When the sirens sound you'll hear a 12 port 5 (closest siren), the 2 WS 2008s in wail, a single toned 2 which died last September do to worn out brushes, and if you listen carefully a single phase 12 port 7 (the faintest, and lowest pitched siren).
