Advanced MX4402 commissioning problem

Hi,

I was wandering if anybody can help me on this one. I have replaced an existing conventional panel with an advanced mx4402. . We have added additional devices and and replaced all of the others with apollo xp95 (19 mcp, 29 opt smoke and 3 heat.
My problem is, I've tried to do the auto learn but it is failing to pick up any of the devices. The wiring has continuity on both positives, both negatives and both screens. (10 ohm on each) looked through the panel readings and its coming back with a loop consumption of around 800mA which is obviously over the max.
There are shorts between any of the wiring, all seems right. With such a small number of devices I would expect this to be 20mA quiescent, tops.

Would be very grateful any advice.
