If 402 room subsystem input powers are not equal to 0, and room subsystem power output is 0, then room divide monitor to judge in the subsystem of room, passive device breaks down.
If the power output of 403 room subsystems is less than or equal to the theoretical value of the critical power output of room subsystem, then the standing-wave ratio that room divides monitor to judge passive device in the subsystem of room worsens.
