This is my latest revision to the M1 Gold layout project (Rev 3) for my HA build. Some of you requested I publish my latest design.

How are you powering/charging the batteries on the two power boards? Also it looks like you have those on the data bus connections, hopefully someone else can chime in, I believe the negatives all will need to be common..
Do I see 14 speakers listed? thats alot! and as noted you need to watch the combined impedance.

I have not shown my A/C wall warts in the diagram for the sake of readability. All the related board requiring A/C power will have the wall warts. I plan to mount power strips for the wall warts and the power strips will plug into a line conditioner/transformer.
Actually, I can have the negatives common via a terminal strip. But to clarify, are you saying that all negative power leads should be common on all the components? So that essentially, both power supply negatives are common to all the other components in the system? This part I am not 100% clear on.
My initial thinking was that if they were separated and 1 power supply should fail, then I would still have part of the system still functioning. Conversely, if they were all common and 1 should fail, wouldn't the remaining one overload? Please clarify this for me.
Speakers. yes I have many. My idea is also to utilize them for the ELK alarm sirens as well. I figure the audio coverage would make it very uncomfortable for any intruder to stand for long.
Thanks
great job bucko, Your hard work has simplify my installation. Am looking at your latest revision. I see that all the negative on your M1RB is connected to a terminal strip. Is that terminal strip connected to anything for proper grounding? Also, what is the difference between image 1 and image 3? Just curious, cos I like and understood the schematics for image 3 better. In terms of charging two batteries, how do you plan to do that? Have you started this project yet?

If some sections of the system have a separate power supply/battery then you don't want to connect the +VKP connection of the data bus to these sections. You do want to connect the other three connections. The NEG connection is your common ground that needs to connect all parts of the system.

Well it's a little hard to tell exactly what connections are in use from his diagram.
But (usually) you don't want to connect the + outputs of two (or more) power supplies together. If you have a board that connects to the data bus and the +VPK connection is used, then the board will be getting power from the data bus. If you have a local power supply powering this board you don't want to the +VPK line of the data bus connected to this board - just the A, B and NEG. The A & B are your data lines and the NEG is your common (ground).
Ok federick, stay with me here. In his diagram, He had the M1DBH HUB connect to the data bus and +VPK using four wires. This means that the M1DBH Hub is getting power from the data bus. Correct? Secondly, he has the input expander (M1XIN) connected to the P212S and the P212s has its own local power supply, then he further use a wire to connect the four pins connector (A,B,NEG,M) from the p212s to the M1DBH HUB. Based on your explanation, this is wrong since the p212S has a local power supply, then the input expander should get it +VPK from the P212s and only three wires should be running from the P212s to the hub (thus eliminating the +VPK connection). Am I right? I know this is kinda confusing I will try to load an illustration to simply my question. Thanks

If he has it connected as you describe then it is incorrect. The M1XIN (getting power from a local power supply) should not have the +VKP data bus connection - just the A, B and NEG connections.
This is an excerpt from the P212S manual:
* * Red Data Bus Wire - Positive (+): This wire is not actually needed as the P212S is a power supply. An isolated screw terminal
marked "Spare" is provided for parking (terminating) this wire or for splicing with another cable if the bus is continuing on. The
important point is that the P212S ONLY NEEDS THREE (3) connections to the M1 Data Bus, Negative (-), Data A, and Data B.
CAUTION: DO NOT connect the Positive (+) wires of multiple power supplies together! It is OK to connect all Negative (-)
wires together, as this will assure the entire system has a common reference to Negative.
In my system, the +VPK data bus connection from the main enclosure to all of the remote enclosures (which each have their own local power supply) is ONLY used to control an ELK relay (in the remote enclosure) that controls the local power supply. When I turn off the power at the main enclosure, the relay in each remote enclosures disconnects the local power supply, shutting down all parts of the system. This was implemented prior to the introduction of the P212S which would also allow shutting down the remote power supplies, in a slightly different fashion.

Thank you. I'm happy it can help you. I'm not sure what you mean by "proper ground". All grounds of the M1 and Elk components should be common to one another throughout the system. HOWEVER, the Elk panel (and components) are NOT grounded to your house in any way. The whole system is isolated. This is different from most panels out there. The ground strip next to the M1RB is actually for another purpose. I want to be able to trigger different sounds or voice messages from the ELK-124 via rules. I only have 4 of the 8 channels hooked up in my diagram, but I plan to use all 8 when I install it. Trying to keep the drawing clean by showing only 4. Example; If the M1 sends a command to the M1RB relay9 to close, it will cause the ELK-124 to play channel 4.
The P212S does the battery charging itself. And no, I am breadboarding all this on paper right now. I haven't ordered all the Elf stuff yet until I lay it all out and make sure I know all the bits and pieces I will need to order. I'm just trying to learn this system same as you for the time being. My townhouse is still being built.

Actually you can see the Blue wire is between the AB terminals to show connections to A & B. I'm trying to keep it looking less cluttered. But good eye to notice that!

You are right. I have the data power wrong in my diagram. Than you for the correction. I have since corrected it. Also the AB data bus for the P212's and the M1XIN's were not drawn very clear. They looked like they were in parallel which was not my intention. I re drew them to show they are in series in the buss to the M1DBH. Finally I added another ground strip so it is clear that all devices are sharing a common ground.
My next diagram I am also working on will show the exact physical component placement on the wall of my server room. Instead of putting everything in cans, I will build a wall space and mount everything in the open. My server room will be secured with a stand alone fingerprint access reader for door entry. It will be independent of any HA electronics, but the door itself will be a security zone in the M1.
Unfortunately, I am limited how I post my diagrams. If I could at least post them as PDF files, you could zoom and also get everything in sharp detail. Right now I can only export my visio file as a jpeg for viewing in Photobucket. Can't use PDF there so I apologize for the diagram quality.

HERE is a Visio Viewer that should let others see your raw diagram. I'm 'pretty' sure it's the one I used for a How-To Schematic I posted here.
