u Can be wired Class X, Class A, or Class B
The FLM-7024-ISO MUX bus isolator module is placed
between devices on the MUX bus. A short on the bus
causes activation of the isolators adjacent to either
side of the short. This effectively separates all devices
between the activated isolators from the rest of the
bus. This prevents failure of the entire bus. When the
short condition is removed, the isolators automatically
restore the entire loop to normal operation.
Functions
Status LED
The yellow status LED lights steady when the isolator
is activated. It is visible:
• In ambient light (up to 500 lx)
• At a distance of 3 m
• At an angle up to 22 5° against the surface norm

Ordering information
FLM-7024-ISO MUX bus isolator module
This module connects to the FPE-7039 MUX expansion
module on the FPD-7024 FACP without using a MUX
bus address. It isolates a shorted section on the SLC
from the rest of the system to minimize
communication loss.
