Class A - answer-Includes a redundant path
-Operation Capability past a single open
- Conditions that affect the intended operation of the signals path are Annunciated
The Class A circuit utilizes
a pair of wires to attach to all of the devices and then a pair returns back to the panel.
NFPA 72 requires that a minimum distance
separates the outgoing and return wires on class A wiring. If a break occurs anywhere
in the circuit, every device is still active due
to the redundant circuit paths. There are four wires, two supplying power to the front of
the circuit and two supplying power from
the end of the circuit.
Class B - answer-Operation Capability past a single open
- Conditions that affect the intended operation of the signals path are Annunciated
The most common installation is Class B utilizing two wires that connect to each device
and an end-of-line resistor for wiring
supervision. Unlike Class A circuits, Class B circuits will not fully operate when a wire
break occurs. Every device down stream
of the break will be unavailable until the wire problem is corrected. The panel will,
however indicate a trouble signal.
