Outdoor Warning System
Be advised: The “Storm Sirens” as they are commonly referred are not intended or designed to warn citizens inside their residence of weather related danger. This system does not take place of a storm radio and monitoring developing weather conditions on your own.
The City of Bixby has installed several new storm sirens to our existing system for a total of 15 sirens that are placed throughout the city. The sirens are computer controlled and radio activated. Each siren has a battery backup system to ensure uninterrupted service in the event of a power failure, which is common during severe weather.
The siren controls are located in the Bixby Police Department and are monitored 24 hours a day. The sirens have a silent test feature, which allows us to test them at anytime. They are tested silently every Wednesday at noon and a full test is conducted the weekly on Saturday at noon, weather permitting. The system also allows us to activate one siren or a group of sirens in an effected area without sounding all of the sirens in the city.
