My Standard Horizon DSC model just had a screw type terminal strip on the
back. I ran an ordinary 2 conductor wire between it and a terminal strip
'hub' that the GPS is connected to. Works fine.

However, since I'm going to be needing to supply the NMEA 0183 to about 4 or
5 pieces of equipment, I expect I'm going th have to install a Multiplexor..
