MAKAHA HAWAII- DSA siren test at Makaha North, Farrington Hwy near Makau St. It's directly across Makaha Beach Park next to the Makaha Shores Condominium. Recorded Tue 7/1/08 at 11:45 AM.

The guys at the beach mentioned the siren is relatively new. They mentioned there was no one there at the siren for its first test but they heard voices coming out of it.

If you listen real carefully you can hear the announcement of the warning siren test on the radio in the background before it starts. I hope this siren clocked in at 40 seconds. When this siren ends you can hear the siren at Wideman St. at Upena further down the highway coming to an end.

Cool video. Is there a reason Hawaii is picking DSA's over other sirens to replace older ones? Are they really even that loud?

Odd how it kind of hesitates on winddown at :56

I recorded a Modulator orDSA back in May, that also hesitates during the wind-down, and it does it more than once. A FileDen and a YouTube link can both be found in the thread below.

Single-toned DSA? Usually the new Modulators and DSAs sound a dual-toned test. Interesting find.

We had Mod's DSA's (all single toned) and 1000T's at Robins AFB, and the DSA's kind of sucked. The six cell Mods did a slightly better job althougth to tone is way too high to be that effective. The 1000T's were pretty bad, we could hear them go off when we were inside buildings and were almost unbearable outside. You could only hear the electronic sirens when they wound down and it still could not compare to the "bolts.

They replaced one bolt with a three cell Mod, then put the bolt back up next to it because people in the MSA could not hear the wimpy mod go off for tornado warnings.

There's not to many DSA videos out there. Nice.
