This was a siren test that was conducted Oct. 5th 2007 in Yorktown IN. It took me forever to get this posted. This was part of our weekly test of the Delaware County siren system. You are supposed to be able to her three Model 5's,
It starts about 1 minute in.

But you can only here the first one. These sirens have been a problem for a while and are slated to be replaced by a new 2001 within the year.
