Notes
•
The maximum number of BPSs that can be connected on a single NAC from sense circuit to
sense circuit is limited by available current and wire run length.
•
Fault tolerance can be increased by using Class A wiring.
DIP switch settings for this application
BPS DIP switches can be set this way for the application to work correctly. Refer
to “Setting the DIP switches” for other options.
