One more thing-

I'm not familiar with that alarm, but assuming all is connected correctly, the next thing is to GROUND the Violet and Violet Black (H1/7 and h1/9 wires) on the brain straight to ground.

If I'm reading this correctly, you NEED to ground those two wires, to send a ground signal to Green / Black and Blue / Black--

so, ground the violet and violet / black wires on the brain.
