Fwiw, LCFD #5 does not own the tornado sirens in either community even though they are at our stations. Firefighters used to be summoned by siren so the infrastructure was in place to locate them there.
Every year we get questions about the tornado sirens. Here is some information about the weekly tornado siren testing:
1. All sirens are tested each Monday at noon. The city tornado sirens are integrated into a computer system that immediately shows which ones sounded and which ones did not. When a siren in the city has an issue, the city is notified. Each county siren is different and is independently tested by the Lyon County Emergency Communications Center (LCECC). They have volunteers in each city who stand by and make sure the siren sounds and performs as expected. If the siren does not sound, a call list for that city is notified.
2. LCECC is only responsible for sending a Dual-Tone Multi-Frequency (DTMF) tone to the siren. This tone indicates to the siren to turn on. Any maintenance issues regarding the siren are the responsibility of that community.
3. If a community does not have electrical power, and that community does not have a siren on backup power – that siren will not work. The community is responsible for providing alternative power.
4. Sirens are designed to run in cycles. They do not run until they shut them off. They run for periods of time. Some are 3 minutes, some are 5. When they cycle off, they have to restart them until the warning has cleared.
5. Often, time is relative in the communications center. A minute could feel like an hour, and 5 minutes could feel like 30 seconds. Communications officers are often managing double the number of responders they normally have with storm spotters out in the county. They are dealing with more radio traffic, extra calls, managing the weather, and also doing their normal duties. Our communities do have other emergencies even during weather. They are triaging what calls they receive all the time. There are only 2 communications officers on duty. During emergencies, they can become so overwhelmed that they don’t get the siren turned back on immediately. Calling up and yelling at them that the siren has stopped does not help. It adds to their work, and their stress. They are humans, trying their best.
