This is the first self-sufficient external sirene I have found on the web. Great sound and nice flashing (programmable with the software).
Easy to install and to fix it due to the 'spirit level' and no electrical external power needed.
Tip: 1 battery is included, if you like just by another one :-)
...you can use 2 batteries in the siren.
I have also ordered the stainless steel cover, great look and feel!
