What Is Being Done To Make The Sirens As Effective As Possible?
Siren coverage is adequate for the major outdoor areas in the City. However, there are many factors influencing audibility. One of the few that we can control is the length of time sirens sound. The longer they sound, the more likely people are to hear them. This is important because, during tests, sirens only sound for about 1 minute. This is just long enough to test the unit, but possibly not long enough for some to hear it. Terrain, sound reflection, noise and wind affect the process; sometimes positively, sometimes negatively. In the event of an actual warning, we will sound the sirens for a longer time.
