No it will not help at all.
All a V572A does is receive all 16 House Codes and 16 Unit Codes for all 256 combinations of X10 addresses and send a power line signal.
It can not even process a Security Message.
Even if it did. The SC1200 has no power line receiver in it and has to use a registered Security Sensor or Remote directly.
Even the V572RF32 model that can process Security Messages maps them to a standard X10 Address. So it also would not help.
