Hall County Siren #37 Special Test - Federal Signal Thunderbolt 1003A

Thunderbolt 1003 at Central Nebraska Regional Airport. Obviously not a regular test. I have to thank airport management for setting this off for me. This was recorded in the airport control tower nearly eye-level to the siren. I couldn't go on the catwalk because it was windy, but it was still a fun experience. This is the only signal that can be activated without going to the EMA offices. This signal is used when airplanes are coming in and are having trouble landing.

UPDATE: As of January 23-27, 2012, this siren has been replaced by a 2001-130.

@mohkfry I'm going back to record this one sometime soon. Probably January 15th. They test the hi lo signal after every regular test, so expect it again sometime soon!

@antiwhoknows Also, does the county own this siren, or does the airport? If the airport set it off for you, i would figure the airport would own it.

[antiwhoknows]

@mohkfry It's owned by the county and the airport uses the hi lo signal to warn people of disasters, usually of airplanes that might have trouble landing.

Attack (one continues signal) mostly for tornado warnings

Civil defense/air raid (wail 3sec wind up 5sec wind down)

Hi-Lo (A Hi note and a Low note repeated continuesly) can be for forest fires and fire calls

That's wat I think these signals mean.....

[antiwhoknows]

@Acepilot235 Alert is the steady signal, attack is the wailing signal (usually 8sec on, 4 off) and you have high low right. Sometimes High low is used for floods in places, at this airport, it's used to warn people of an airplane that might have landing problems.

@antiwhoknows if im not mistaken, on a thunderbolt, the attack mode is usually 4 on, 8 off
