Look for any motion with form "c" relay.

Most mfgs make a cheaper version with just NC and one with form "c" which is
common, open, closed.

Use a low current relay to oeprate your alarm device triggered byt he
motion.  The contacts in the motion relay can't handle much current.

Can you say, "Pzzzzzt."
