City Authorizes Purchase for New Siren

North St. Paul City Council recently authorized the purchase and installation of a new Federal Signal siren for severe weather warnings. Federal Siren pictured at right. Noon whistle siren at left.Siren

Ramsey County Emergency Management and the Ramsey County Dispatch Center are implementing a county-wide siren controller update. The current outdoor warning sirens in Ramsey County are activated using a system that is now well over 30 years-old and is very unreliable.

All communities in Ramsey County will benefit from this siren control update. It opens the door to a more targeted alerting system where sirens are sounded only if they are located within the severe weather warning polygon defined in the National Weather Service alert. This would significantly reduce the number of sirens that are sounded under "blue sky and sunshine" because the threat is on the other end of the county.

Because of the unique tone of the Federal Signal siren, which is intended for severe weather warnings, it cannot be used for the City’s daily noon siren. The new siren would be added next to the existing siren on the roof of City Hall. This will allow for the continuation of the noon siren and the specific severe weather warning siren.

The base cost of the new federal signal siren is $18,503 with installation costs of approximately $4,000.
