Yes, it's an autonomous power source for the various zone detectors, as well as the Arduino. I like the block that you have posted above.

I have now replaced the power to the terminal block with a 2a mains adaptor and ordered a new Arduino...here's hoping! 

No - the arduino controls my somfy blinds and I was making it a bit more robust. What is Tiger's project? 

Why can't you read the amperage from the 12v power output? Also, how would I know what the draw is on each device if I can't measure it?- is it a case at looking at the datasheet on each one?

so I tried to read the amperage this morning off the power block and as soon as I touched the probes to the connections, it tripped some of the attached zones on the OP2.

It was a Mega 2560 clone, DC input is rated for 12v

The earth ground on the Omni goes to the main house earthing bar. I haven't tested the arduino (it doesn't power on now at all) but reading forums, it seems likely to be the voltage regulator.    But the current draw idea makes a lot of sense - if there's too much being drawn, then it will have...

No, it was a straight 12v. I had the arduino running fine off a different 12v supply with the USB also connected.   There is no reference between the ground on the terminal block and the ground of the USB (hence my comment re floating grounds...)    USB was connected to a minimac, in turn...

I have an omnipro 2 with lots of sensors attached. As each of these sensors require their own +ve and GND supplies, what I did is run a couple of wires from the omnipro 12v and ground output to a terminal block which then supplies all the attached sensors. See the picture; the top of each block...

I am in disbelief. I reconnected the board and let it sit for 24 hours- no problem. Uploaded the old configuration and within half an hour, started to get the battery low message again. I changed the battery and I updated the firmware to 4.0b and got a voltage reading of 225 but 2 days later...

So I finally got the board back today from HAI after a repair.  The repair note said: Problem Found: Battery issue - Q1 Blown/ R70 and Q9 short Action Taken: Replace Q1, R70 & Q9 -Update FW & reset to factory default

It doesn't crash but the battery still shows as bad. Tried the disconnecting for a long time, with no success :-(

I tried the sequence in the manual with no success. I don't know what the polyfuse is, so can you please advise ? I live in Israel (I brought the board out here) so it's not easy to just send it back for servicing. 

voltage on the new battery is only reading at 12.5v which is the same as when I put it in 

I may give that a try- otherwise I have no idea how it will be possible to send the board back as I don't have a replacement one to put in temporarily (and I don't live in the US either!)
