Adopt-a-Siren Program

The O’Fallon Police Department invites citizens throughout the City of O'Fallon to volunteer in the Adopt-a-Siren program. Citizen volunteers are needed to help monitor each of the tornado sirens in the City’s Outdoor Warning Siren system and report whether or not specific sirens are working properly.

Any citizen can report a malfunctioning siren by calling 636-379-3816. However, the Adopt-a-Siren program will allow the Emergency Management team to contact knowledgeable volunteers directly if there is a question, concern or if additional information is needed for specific sirens. 

Interested O’Fallon citizens must be within ¼ of a mile or within a block of adopted sirens, and they should go outside when sirens are tested each month so that accurate observations can be made. For that reason, up to five citizen volunteers for each siren are requested. Participation is completely voluntary and no legal obligations whatsoever are expected of observers.
