Ness D8x with Bosch sensors Q

**blue** · 27-03-10, 07:12 PM

If someone can give me a little bit of light on this one, trying to connect 3 bosch sensors to the ness d8x. This isn't my first or last install and as I've tried everything I can think of I still have a problem with the individual zones closing. The first one: no problems, once I connect the second PIR: both zones end up open?
Heres a pic

What can one say two great pictures

Picture one shows panel connection with zone 1 now terminated with two wires and End of Line resistor remove.

Picture 2 shows PIR connection but misses the most important EOL resitor and the sometimes normally required tamper contacts

Please read the D8 manual on how to connect zones as you will need to. your connections will never work and your o/c problem will remain until you can understand the basics of how End of line Resistors work on any security alarm panel.

You are so far the definition of a STI (no not a sexual transmitted infection) more like a Self taught I---.

I bought a heap of these bosch pir, seem great to install and easy. I put EOLR on the NC & T on the right half of the terminals. Followed by Yellow common on the NC, positive, ground and Green on the T(left and side). I guess every installs is different..

All those zones with resistors are sealed ok because the resistor is there, that is what the zone is looking for
Where is your resistor for zone 1 ?
