Test 3: Input Return to Output Return—Use the following procedure:
1. Starting at bus A, connect the negative test probe to the RTN input power terminal and the
positive test probe to the RTN output power terminal for circuit 1 ( Figure 9 ).
Figure 9. Test 3: Input Return to Output Return
2. Verify that continuity exists between the specified terminals.
3. Repeat the test procedure for each remaining circuit (A 2-7, B 1-7).
Test 4: Alarm Terminals—Use the following procedure:
1. Starting at the top set of alarm terminals on the right rear side of the panel, verify that no
continuity exists between the C and NC terminals( Figure 10 ).
Figure 10. Test 4: Alarm Contacts
2. Connect the test probes between the C and NO terminals on the first set of alarm
terminals. Verify that continuity exists between the C and NO terminals.
3. Repeat the test procedure for the other set of alarm terminals.
Note: This procedure tests the alarm indicator contacts as they should be with no
power being supplied to the panel. In this state, the normally open (NO) contacts
should be closed and the Normally Closed (NC) contacts should be open.
