Bosch AMAX 4000

[Vrix]

Hello,
 
I'm new to alarm system's, I basically got stuck by my employer to try and figure out how to make this Bosch system work.  I have it mostly figured out except for the motion sensor.  The sensor is a Bosch Blue Line Gen2.  The problem I'm having is that it dosen't seem to make a difference what way I wire it, I always get a Zone Tamper Fault when I detects someone, whether the system is armed or not.  I'm not sure what to do.
 
Any help will be greatly appreciated.
Thanks,

The motion detector has two sets of contacts, one for motion detection and a second contact for tampering.  If these are both wired to the panel, it could be that you have the wiring crossed or the zone definitions are wrong.  Check the wiring on both ends and make sure that the zone definitions are correct.  It sounds like the motion contact is connected to a zone that is defined as a tamper zone.

@ RAL, the Bosch product he is discussing is NOT a NA panel and subsequently wired completely different and to completely different standards and governance, though the concepts are somewhat similar to how they're wired over here, their implementation and subsequent programming/functionality are vastly different than what you're describing as causing the issue.
 
As such, in the EU the devices would be typically wired using DEOL with one resistor in series across a set of contacts (typically tamper) and the second resistor wired in series with the zone cabling, with the alarm contacts and tamper contacts being connected in series.  (page 5 of the installation manual).

@DEL - I had looked at the manual and saw the wiring with the dual EOL, but didn't take that to mean that it had to be wired that way. Thought you could still wire a separate tamper zone.  Thanks for teaching me something new.
 
So if that's the way it should be wired, it sounds like a possible cause would be having the EOLs wired incorrectly. E.g. the motion contact is wired in series with its EOL and the tamper contact wired in parallel with its EOL.

@ RAL, it's usually something that could be changed, but definitely not going to be default or easy to do off the cuff due to the regulations for EN and EU based products (DSC alarms non-withstanding) they typically make it a little more difficult for a non-compliant install or component layout.
 
Giveaway to the application/installation is going to be the transformer in the can and the voltage/HZ, combined with the EN spec. You're almost never going to see HV in the same can as LV in NA without a very large divider.
 
Assuming the panel is configured with basic defaults, it would be entirely likely that the system is looking for DEOLR, and typically, that would be one resistor in parallel with the tamper and one in series (or parallel) on the PIR relay, depending on the NO/NC application and functionality of the PIR, same with EN, BS and SSAIB standards, which I'm not truly up on anymore as I don't have to draw out the typicals for installs overseas projects anymore.
