Apparently BA is going to propose a replacement for sirens from the oldest installation. I'm assuming Whelen since they've had them since they operated WPS3000s. Good news!
Also they have switched to Wail for tests and tornadoes. And they will do regular tests for storm season after years of no audible tests.
