-48V DC power supply to the
controller (A or B) is low or
missing. Under normal condition
power is shared between controller
cards.
Check power cable connection or
battery voltage of the reporting
controller card.
Alarm Input 1/2/3
Detected
Contact closure was detected on
the indicated alarm input (1,2, or

alarm system should provide open
contacts to the alarm inputs.
Providing contact closure to an
alarm input results in this alarm.
The alarm is cleared when the
contact is opened.

same functionality; for example,
one supports EOC/TMC and the
other does not.

controller (see Replace Controller
Card on page 16-3 or update
controller with compatible
software (see Update Controller
Card Software on page 17-1).

(A or B), the remaining controller
card is now active.
Insert a good controller card into
the empty slot

Controller Card Software on
