The model LL-SG2-*/* transponder is available as part of the LIFELINE status-monitoring system. The LL-SG2-*/* transponder continuously monitors node parameters, executes commands, and reports to the polling computer when interrogated. Section 2, “Overview,” provides additional information regarding status-monitoring functions.

Detailed instructions for installing the LL-SG2-*/* transponder are provided in the Transponder for SG-2000LL-SG2-*/* Installation Sheet, packaged with the transponder. Following physical installation, the transponder must be added to the software system and the alarm parameters must be configured. To complete these tasks, refer to the LIFELINE for Windows Software Operations Manual.

If your nodes transponder was installed at the factory, it was tested and calibrated using special automatic test fixtures. It cannot be repaired, calibrated, or aligned in the field.

If a problem is suspected, the LED visible on top of the transponder is useful in troubleshooting. During normal operations, it indicates the following:

The LED illuminates when the module is powered up

A flashing LED indicates two-way communication with the LL-CU control unit

A dark LED indicates loss of communication or power
