If not too difficult, disconnect the PC5108 from the keybus so that only the keypad is connected.  902 / 903 (should only show the keypad then).  Power cycle and see if it clears the Gen Sys Supv.

Ideally, both the keypad AND the expander should be homeran to the panel, not daisy-chained as you described.

Hi,

The keypad is pretty close to the PC5108 board (10 cm). That is why the key bus is connected in daisy chain.

I disconnected the keybus on the PC5108 board, reset power, 902 + 903 commands. It displayed Keyboard 8 (without the Zone 9-12 and Zone 13-16). The Gen Sys Supv fault disappeared.

I reconnected the PC5108 board, reset power, 902 + 903 commands. It displayed Keyboard 8, Zone 9-12 and Zone 13-16. The Gen Sys Supv fault occured again.

Can it be a failure of the PC5108 board?

I checked the Keybus voltage on the PC5108 board. It seems OK (Vred-black = 13.5Vdc ; Vyellow-green = 2Vdc and 11Vac). All the sensors are in short circuit (all doors/windows closed, unused inputs short circuited)

You can see the PC5108 board: http://imgur.com/d14kCsv

So the issue lies with the PC5108.  Disconnect the keybus wiring on the PC5108 board, including untwisting the wires most likely, to ensure each is making good contact with the terminals.  I'd also meter each wire of the keybus between the panel and PC5108 verifying continuity RBYG of that wire run.

Looking like the PC5108 may be bad, but you want to test it thoroughly to be sure.  I seldom have seen DSC modules fail.

Yesterday when I disconnected the PC5108, I only took each twisted keybus wires off the PC5108 terminal. So the continuity of the wires from the main panel to the keypad is good, even if the connection of the four set of 2 wires were only done by twisting them together. (Wires from main board to the PC5108 (not conected to the PC5108 terminals) twisted with the wires from the PC5108 to the keypad)

Can you explain how the keybus communication fails with the PC5108 and that the LCD screen displays the right informatino about doors/windows opening which are connected on that PC5108 board?

I'd like you to disconnect the keypad from the PC5108 and homerun it to the panel.

Next, disconnect what appears to be other power devices (i.e. motions, glassbreaks, smokes) from the PC5108 RED terminal and move them to the AUX+ terminal (it looks like you might have 2-3 in that twisted bundle besides the keypad and run to the panel).

So...
power down
make changes
power up
check if the trouble clears

I moved the other power devices from the red to AUX+ terminals. No impact.

I give up. I don't have the time and the material to homerun the PC5108 and the keypad. I will call for service when I will be ready to use my alarm system.

Thank you very much AlarmMike for your time and very fast answers to my questions. I am impressed by your website and your good service!

Ha!  Not my website.  Just a self-employed installer that monitors this forum.

Sorry we didn't resolve it quickly.  I was under the impression the cables for the keypad and 5108 were in the main cabinet where they can be easily relocated to the main panel.

Final note.  With info provided up to now and without any further troubleshooting, it appears to be a faulty PC5108 module.  They're relatively cheap at around $35.00 if you decide to move forward with DIY.  Otherwise, you'll be looking at about $200.00 for a company to repair it.
