dsckeybus Fault #12

Closed thunderwood19 closed 3 years ago

thunderwood19 commented 3 years ago

After hooking everything up, I am currently getting a keybus fault error on the main alarm panel and am unable to use the Alarm system.

This would be a problem with your wiring. Bad ground, etc.

thunderwood19 commented 3 years ago

I believe that to be the issue aswell, just can't seem to diagnose the point of failure. Grounds are all tied, wiring diagram was followed to the t. 16081659101799160145274091206960

transistor pinout correct? Correct values for resistors? etc. Something is shorting one of the lines or a bad ground, those are the only possibilities as far as I can see.

Just got into wiring, but resistors are simple enough. I think I got the transistor correct : 1608168889197532740925601195787

Left: to green wire Center: to 1k resistor and then do Right: to ground Transistor is a 2222a

e b c. E=ground,b=1k, c=green wire. I think you have e and c backwards.

Ok, so that was a problem. Switched the ends around and now it seems im a little further along. The issue now is that the alarm system only works when the black wire is not connected to the nodemcu

thunderwood19 commented 3 years ago

Re did wiring on a new board: 20201216_210831 Left to nodemcu, riright to alarm panel.

Connected to panel: 16081751680137794887259337777401

Wires to ground bundled and then connected to other grounds on panel.

Panel is currently spazzing out and sensors aren't responding. Nodemcu was flashed with latest and zones were configured prior in the yaml.

You still have a wiring issue somewhere. Can you measure your resistors to make sure they are all above 1kohm. Looking at the picture the multiplier looks to be black which is a 0. The values on the schematic are in KiloOhms, (K) not ohms. (ohms) I should make that more visible on the schematic.

thunderwood19 commented 3 years ago

Resistors are all showing as their proper values (10kohms, 33kohms, and 1kohms). The following are the Resistors im using. 20201217_075159

Dilbert66 commented 3 years ago

Well, I don't have any other suggestion. It's still a wiring issue somewhere.

Dilbert66 commented 3 years ago

One part that does not make sense in your wiring is this resistor? The nodemcu ground should be direct to the panel ground. No resistor in between. image

Dilbert66 commented 3 years ago

I don't see the 1k resistor between the nodemcu and the transistor base. That's your issue. Your resistor is not on the right line.

thunderwood19 commented 3 years ago

The misplaced 1k resistor was it. I really appreciate your help with troubleshooting this as I learned alot from this experience. Keep doing amazing work!

Good stuff! Have fun!
