The purpose of the Warren County Outdoor Public Warning Sirens is to alert the general public of the existence of, or potential existence of a tornado situation anywhere in Warren County. The main objective of the sirens is to alert those individuals who are out of doors and away from the other established means of notification, such as commercial television and radio, weather alert radios, and so forth. These sirens are not designed to be heard inside a structure. In order to make the Outdoor Public Warning Siren System efficient and effective, a consistent method of operation is paramount. As the Warren County Division of Communications is the activation point for a majority of the sirens, it is imperative that its’ personnel know under what conditions they are to activate the siren system.

DESCRIPTION AND GENERAL USE OF OUTDOOR WARNING SIREN SYSTEM

System wide activation will activate the sirens utilizing the County’s fire paging frequency (453.375 MHz). The sirens shall automatically sound a steady tone for no less than 3 minutes and then reset themselves. This method is the nationally accepted manner of sounding for a TORNADO WARNING. Sirens not meeting the basic requirement for sounding, will not be considered a bona-fide siren for warning of a tornado situation.

INDIVIDUAL SIRENS SHALL NOT BE ACTIVATED FOR A WARNING. ANY SUCH REQUEST SHALL RESULT IN A COUNTYWIDE ACTIVATION OF THE SYSTEM.

System wide activation will also be utilized once a month for system testing.

The Outdoor Public Warning Siren System will not be activated for any other weather related incidents. This ensures reliable TORNADO WARNING and reduces confusion among the general public. The public in Warren County will fully understand that activation of the siren system means "TAKE SHELTER, NOW, TUNE TO NOAA WEATHER RADIO OR LOCAL MEDIA FOR INFORMATION !”

MAINTENANCE TESTING (SELECT OR GROWL TEST)
Most, but not all, sirens are capable of select (individual) testing activation. Select activation is also referred to as a “growl test”. The siren is designed to activate for 5 to 15 seconds to verify its proper operation. The Director of Emergency Services or his designee shall be notified any time a test is requested on any siren activated from the Warren County Division of Communications.

SIREN OWNERSHIP
Sirens are owned and maintained by the political subdivision in which they are located. Any questions, suggestions and/or complaints by the citizenry in that area are to be referred to their local government.
