I bought this to replace one of the pre-digital PIRs that I had attached to an older Astron 64 light. The only issue is that this is not completely compatible with the older lights because the connectors now have a different pin configuration. Not one to be deterred I got out my soldering iron and spliced the old connector onto the new PIR. This worked perfectly. Once installed the new digital PIR is much easier to set up. If like me you are buying this to replace one from an earlier model be prepared fro a little DIY.
