Hello Richard

There are many issues raised. Because of tsunami there is a suggestion that local councils install sirens in NZ.

But they are talking about sirens with three different signals.

I assume from what I know from you that this project is doomed to failure. But is your unit a viable option?

1. Power source?
2. Emergency power source?
3. Capability to producing different sounds?

I understand that with your horns, you can get better coverage, and indoor coverage with fewer units installed.

I invite everyone who has a problem hearing their city's warning sirens to visit my personal page. If you live more than a mile from the nearest one and are indoors or driving in your car, chances are you won't hear it. The now universal excuse of the sirens never being intended to warn people from indoors is getting old. They just need something better that can be heard from indoors from over a
mile.

My units run off available power or could have a backup generator or battery backup. As whistles respond instantly to changes in pressure, they can be modulated via a tremulant (an industrial strength version of the tremulants on pipe organs) to produce steady tones or warbling sounds.
