Made ESB,ESS and AESS high with ESH low(I think this is phase 1 key input) the firelight still on at bottom landing with door open.

Does any one know if there is a input for the controller to confirm it's at the fire floor?

Does anyone know what AESP output suppose to be. I am sure it's suppose to be high, or what input to get this output?

I can rule out any chance of being an I/O board or the interface board.
