1.
Connect the Constellation radio to other equipment.
For connector pinout information, refer to
Appendix A .
2.
Connect the customer-configured alarm wires.
3.
Connect the Constellation Radio to the antenna or to a dummy load.
All Constellation radios, in terminal or repeater (when applicable)
configuration, provide 8 alarm inputs and 8 relay outputs. These 8 relays can
either provide information about the radio to a non-FarScan NMS, or be used
to activate (from FarScan) external devices such as a generator, air
conditioning, and so forth (housekeeping). These 8 relays are programmable;
the first two relays are predefined at the factory as LOCAL MAJOR and LOCAL
MINOR but can be programmed for customer use.
Located at the top left side of the radio ( Figure 3-13 ), this 50-pin D connector
( Figure 3-14 ) is available for customer-configured alarms. The SPU Controller
provides 8 opto-isolated alarm inputs. The system provides 8 dry-contact,
relay outputs as defined in
Table 3-10 . Input level of alarm input shall be open
or ground. The Service Channel provides the Callout outputs. Table 3-9 lists the
relay specifications.
