Classic Siren Video 37. Filmed in 2007.

This 10-minute siren test was a special request by city officials, and was conducted during a normally scheduled county wide siren test. The 3T22 has a blocked intake causing the high pitch and pulsing sound when the solenoids were activated.

This siren was removed and replaced with a Federal Signal 2001-130.
