2 trigger sources, one output, all 120VAC

[Semo99]

I need to assemble a device to operate a 120VAC 1/8hp fan motor triggeded by one of 2 120VAC switching devices. One device will be a standard IR motion sensor; the other, a countdown single pole switch. I am assuming that most motion sensors are not equipped to handle voltage on the load side (supplied by the countdown timer) when the motion sensor is open since they now all appear to be solid state.

I am sure I am over-complicating things. Thank you for your assistance!
