It depends on the city. I guess if it stays on testing day then yes but don't try it until you look at your local ordinances.

Engesig re-brands Federal Signal products for the South American market. They also sell a modulator, A Q2b and a Model L. They also make such oddities as a double STH-10 in a 2t22 style setup.

Sirens were invented by Charles Cagniard de la Tour. Also, he wanted to use the siren as a warning alarm on ships. And yes, the siren was also used for music so they can measure exact frequencies
