Does the PIB300 connected to AD300 both require separate power supply?

They could be powered by same unit, if they are close enough. With data pair and power pair of wires the power supply can be at the PIB300 feeding both AD300 locks, as long as current supplied meets around

           300ma per lock, plus the draw for the PIB300. The power supply is located at or near the PIB300/PIB301 for short wire runs, or local to locks if located far from the panel.
