Class B is the most common type of pathway on fire alarm systems. A Class B pathway does NOT have a redundant (return) pathway, so any equipment located on the Class A wiring creates a full loop back to the panel, class B just has an EOL resistor. Benefit of Class A is the ability to continue having a functional
