After being deactivated for nearly three months, the STH-10 in Trexlertown has been reactivated a went off for the first time. The problem was that the siren was having radio trouble and timer problems. Although the siren's fire signal, has not changed and sounds like it did before it broke. I wished I got the tones rerecorded, but who knows if it was still broken. If you listen closely, you may hear pitch fluctuations because of it being extremely windy.
