Figure 9-37
is a simplified circuit diagram of the two relay contacts.
The relays provide form A (single pole, single throw and normally open) contacts for
activating external circuitry and devices. Operation of the relays is determined by the
system database.
Only two of the three relay functions (RLY1, RLY2, RLY3) can be selected. The
selection is accomplished by P4 straps located on the U-RMI Office, RMI Office,
U-MR Office and MR Office cards (see
Figure 9-37
).
Table 9-27
defines the
position of the P4 straps for the relays selection.
