Has anyone used an aurora (Honeywell) motion sensor (PIR) with arduino?

It is different than the Parallax one because it has 4 leads instead of 3. It is deigned for an alarm system so I dont know how to wire it. Any help would be appreciated :)

Haven't used one, but check out the installation notes here. Looks like two wires are for 12 V DC power and two wires are for the alarm. Some models have two more wires for an anti-tamper circuit.
