Customer alarm input/output (IP/OP) cable (X) details
Alarm connectors
There are two ALARM connectors on the UBS Macro S SI:
• CUSTOMER IP 1 -12 OP 1 -4 connector
• CUSTOMER IP 13 -24 OP 5 -8 connector
Each ALARM connector provides 12 inputs and 4 outputs. A total of 24 inputs and 8 outputs are
available.
Function
ALARM connectors provide for Customer Defined Alarm Inputs and Outputs. The customer can
connect BTS site alarm input sensors and output devices to the UBS Macro BTS , thus providing
alarm reporting of active sensors as well as controlling output devices.
The S SI detects signals from customer input sensors and reports the detected signals to the
DMI controller , which in turn reports the detected alarm to the OMC -R, where it is displayed as
defined by the customer .
The S SI also provides switched relay contacts to customer output devices. The S SI controls
relay contacts according to output control signals from the DMI controller , in response to
customer defined commands entered at the OMC -R.
