Edwards and Faraday Coded Pull Demonstration

Demonstrating an Edwards 1251 (Code 4-4-1) and a Faraday F652T (Code 5-1-6) coded pull station using a Simplex 2903+2901-9806. An Edwards 270-SPO non-coded station was wired to the right of the Faraday station but not used. The pull stations are wired up as they would be in a real building, so when I pull the Edwards pull station, it cuts off the Faraday pull station from the circuit, hence why it is still doing rounds of code but not sending them to the horn, while the horn does the Edwards' code. This is to prevent more than one code being transmitted to the horns at once.
