That link didnt work for me.I did find the
post mentioned. I'll cut.paste it here for you:
What you need are:
(1) POWERFLASH Burglar Alarm Interface
(PF284)
(1) LED Detector Probe from
http://www.smarthome.com/8013.html It is really simple to put together, all
you do is trim the edges of the LED
Detector Probe until it is small enough to
not cover up any of the leds around the
armed led. Then you stick the detector
probe on the Armed LED. Be sure that it
sticks good and there is no light coming in
from around the edges. Then you take the
end of the probe cord and connect it to a
powerflash unit.
The Powerflash must be setup for Mode 3,
Input as Dry Contact. Then you set the
unit and house code dials to a light that
you can see from the outside or maybe you
could even set out a night light in a
window beside the door, either way on an
x10 module set to the same unit code and
house code as the powerflash unit. For me
I use my front porch light. Now whenever
your security system is armed whatever
light that you chose will turn on, and when
it is disamed will turn off.
Now you can leave your house with your mind
at rest because you now know that you are
protected. Enjoy!
