Hi All,

I spoke to Apollo and they said it must have end of line termination added.

The Apollo tech said a resistor needs to be in place between L1out and the spare + terminal on the PCB. As far as I can tell this puts a resistor between the + and - on the power supply.

The tech said the resistor size is determined by the alarm manufacturer. 
I think this is the equivalent to 2.7K on the Hochiki diagramIf I follow the Hochiki diagram I also need a 4.7K on the zone wires (NC and C on the detector)
