The optional LIFELINE Status Monitoring System (LL-SG2) enables you to monitor the SG 2000
from a headend or a remote location. The transponder consists of a plug-in module mounted on the
main RF board. If you do not employ status monitoring and use redundant receivers and/or
transmitters, a manual control board (MCB) occupies the same position on the main RF board.

The entire LIFELINE system includes:
LL-CU control units
Are connected to the system at the headend and interrogate each
SG 2000 field transponder with FM outbound and inbound
transmissions. A variety of outbound and inbound frequencies can be
selected depending on the configuration of the system. The control unit
reports this information to the status monitor computer.
