Hi all,
I have a really nice RAB motion sensor/halogen flood light set up, and
I want to run a wire from the output side (which turns on the floods)
into my house so that it notifies me with a small light bulb in my
living room.
That part is fine, but I want to have a momentary buzzer or chime come
on when it is first tripped. How can I do this?
Thanks!

Here's what I did. I don't know if it's legal but it works quite
well.
Take a feed off of the wire going to the light socket. A simple
western union connection works well. Bring the wire back through the
lights housing back into the box and then into the house. Mine is
done to be inside a closet to give me some room. In there power a
Square D "One Shot" timer relay. The timing is variable with a knob
on top. The power comes on and energizes the relay and it stays on
for the time set on the relay. Then it shuts off the controlled
circuit until the power goes off (and comes back on) on circuit that
powers the relay. I ran my doorbell circuit through it so if anyone
walks up my driveway, it rings my doorbell.
I also put on two switches. One for the power so I can shut it all
down and one on the bell circuit so I can shut that down and leave the
light working.
The relay should be available any any electrical supply store. I
tried to figure out how to do it other ways and didn't have any luck
until I threw myself on the mercy of the guy at the electrical supply
house who said "I have just what you need...."
