Guidance on Testing


(1)

The siren test time is designed to roughly coincide with the weekly National Oceanic and Atmospheric Administration (NOAA) Weather Radio tests. Tsunami Warning Sirens will be tested on Wednesdays at 11:00 hours (a.m.) for routine testing of tsunami warning systems. Testing will be done on the first Wednesday of each month at 11:00 am.

(2)

The recommended siren test duration is not to exceed 60-seconds excluding voice message, except during system coverage evaluations, unless using a unique sound for the test, such as Cows or Chimes.

(3)

A sign or placard shall be affixed to each siren stating the routine test time and day.
