Does anyone know how to attach a PIR to a Hauntmaster Products flex ECT?
I have both and need to connect the PIR so my props will all work this year.

I have a Combo Flex which came with a PIR. Sorry but I don't have a Parallax unit to check out the hookup.

You should check Jim's Flex page. It shows the connection points.

And the Parallax documentation has the outputs.

I don't think you'll be able to connect a Parallax PIR to that circuit -- it's expecting a N.O. contact closure (dry contact), and the Parallax PIR has a low-to-high TTL output (wet circuit).

Scary Terry Sent me this circuit that should work.

You'd be better off buying some 10$ Regent motion sensors at Home Depot and hooking them up to a 120 Volt relay. Then having the relay hit clsoe the contacts for the trigger on the ECT.
