Connecting the Alarm Contacts
1. Connect the NO (Normally Open) alarm contact of the MAIN TRACER BBP (labeled 1 below) to the MN alarm contact in the IN alarm
block of the TRACER MPS (labeled 2 below). The TRACER BBP provides two sets of alarm contacts; for normal configuration, use
the NO located in the MAJ (Major Alarm) block.
2. Connect the COM (Common) alarm contact of the MAIN TRACER BBP (labeled 3 below) to the COM alarm contact in the IN alarm
block of the TRACER MPS (labeled 4 below). Repeat this step for the STANDBY TRACER BBP.
3. Connect the NO alarm contact of the STANDBY TRACER BBP to the SB alarm contact in the IN alarm block of the TRACER MPS
(labeled 5 below).
4. (OPTIONAL) Connect the TRACER MPS alarm contacts (NO, COM, NC) in the OUT alarm block (labeled 6 below) to your external
alarm monitoring system. Failure to follow this step will not affect TRACER MPS redundancy operation.
Only the TRACER 2603 BBP provides the optional MIN (Minor Alarm) terminal block. Connecting the MIN alarm contacts allows the
TRACER MPS to perform a system switch when a minor alarm condition occurs. Please refer to the TRACER 2603 User Manual
(ADTRAN P/N 61280003L1-1) for a detailed listing of major and minor alarms.
