PS561 Console and TM751 Mini Transceiver on same House Code?

[everydayflyer]

OK I know two TM751 can not be on same House code but how about PS561 and TM751?

The PS561 Security Console also Tranceives X10 RF signals on the House Code it is set to. I don't know if it is polite but the TM751 is not. So in some situations they may step on each other.
