Bill,
I though that this would be the hard part and you have made it easier.
Would I be able to trigger it with motion sensors, laser or something along that line?
Can I record my own announcement on this unit?
Thanks again
That one can be triggered by any device that closes or opens a contact I.E. a motion detector's relay output, a door or window switch or X10's UM506 "Universal Module".
No, you can't record custom messages.
There is one manufactured by Visonic that allows you to record any sound (including voice) you want by use of it's built-in microphone, and like the amseco one has a built-in amplifier... Unfortunately, their web-site isn't responding at the moment, so I'll have to try to find a link later.
Additional 01/19/2007: The Visonic module is their SP-3 (the web site is still down though
).
