Hi,I tend toward modular wiring rather than daisy-chaining or paralleling downstream. Functionally the switches operate in parallel with the photo-detectors, but that can be messy wiring that makes later troubleshooting difficult. For the 116 schematic, what about adding two pins to P5 and P6 so there is a 4-wire run to the sensor and an independent 2-wire run to the switch (or a 3-wire run to a switch pair)?

Yes that is what i would do, multicore cable from the Module to the Signals / Sensors, and another from the module to the Control Panel for the Switches (these will be push button, not all modules will need switches though)
As a foot note not all modules will need both sensors, some will operate purely as trigger from sensor, then time elapsed to form the 2nd trigger. If this makes sense !!!
