Was out in Elmira this morning so I recorded the Saturday test of the towns outdoor warning sirens. The system consists of the original STH-10 fire call siren, a Model 5/7, and a second STH-10 purchased in 2004.
The sirens are used to warn of industrial accidents at the refinery in town, as well as tornado warnings.

Unfortunately, the Model 5/7 did not activate, and the sirens only sounded for a short blast.
