I don't think you'll be okay cascading them. You might be okay paralleling them if the sensor has enough output current to operate all the emitters.
A Xantech distribution block has four circuits. Each circuit places a 470 ohm (IIRC) resistor in series with the LED. So if you take one output from a distribution block and put another block in series with it, then you'll have a sensor output, its current limited by a 460 ohm resistor, feeding a distribution block that will put another 470 ohm resistor in series with the LED.
If you put the blocks in parallel, you won't have that problem.

A good answer is easier with a clear question giving the make and model of everything.
