originalevil:
I looked at the siren you point to, but I can't figure out whether to turn it on would simply be a matter of giving it "juice". If that's the case, wouldn't it be simpler to get one of those 12v sirens (could even have a backup battery attached to it in case power goes out) and use an X10 module to turn it on? - something like a "universal module"?
This would be much cheaper, and more portable - no need for new breaker, no need for more wiring (possibly a new outlet for the universal module though.)
Thanks,
Frank
Those are very good points, but, for me, the idea of an outside siren is that the siren is placed out of reach of a villain and it can't simply be unplugged. The benefits of this siren are that I can install it at the peak of the roof, in a box that meets code, is not easily accessible, and, because of its size, is not easily seen. Of course, once it starts making noise, it will not take long for it to be seen. Reaching it is another matter. Since the switch is wired inside the structure, it can't be unplugged.
Also, the XPS3 responds to "All lights on" but doesn't have soft start. It is a win/win situation.
