| The
SD505-6IB isolates a short circuit wiring fault on a
Class A (Style 7) and Class B (Style 4) SLC loop. Normally
if the FACP detects a short on the SLC loop, the entire
loop can be disabled. When the SD505-6IB is attached
to the loop, a short, open or ground fault occurring
on the SLC loop will be detected as a trouble but all
SLC devices will continue to operate.
The
isolator module fits underneath the SD505-6AB detector
base.
