You need to use a meter to see why you aren’t getting P24 to the IN relay in the controller. We know you have it to the car top inspect switch, are you getting through that N/C contact down to the access switch? Through the N/C access switch contact to INB in the COP, back to the controller on INB. If you have 24v at INB on the relay board pull the IN relay and put your meter across the coil terminals. If you have 24vdc there you have an open coil or the wrong voltage relay.
