Notes:
1. Trouble indicates that a trouble signal will be generated at the control
panel under the abnormal condition.
2. Alarm capability indicates whether or not an alarm signal can be
transmitted to the control panel during the abnormal condition.
3. Isolated redundant loop operation is a method of protecting, or
isolating, entire physical zones of devices on the communications loop
from faults that occur within other areas of the loop.
