Milano electronic air-raid siren from China

[AllSafe]

I don't know whether it's a unique product or not, but Hangzhou Milano Signal Technology Co. Ltd. makes a modern electronic omnidirectional siren available in 500, 1000 or 2000 watt models. I couldn't find out much more but here's the link:

This is one of the very few companies that offers sirens which can accept a hanging unit.

Good find.
