Finally! This is what I have now! We had 4 Pavian sirens in Australia and it was used for Bushfire warnings. These Pavian sirens are publicly mounted. There are more! There are SIRcom siren, a SIRcom siren system in Tenterfield, NSW, Australia, Whelen WPS series in Queensland, Klaxon publicly mounted in Ferny Creek for Bushfire warnigs and fire callouts, Vortex R4 sirens for flood warning, Whelen IPS-400 for cyclone warnings or hurricane warnings if you say in other countries but sorry, there are troubles in taking the picture. As with whelen, most of them have visualert.
