We have a few of the tac 20's if the power is lost or another fault occurs the door will disconnect and we have to turn the doors back on. What would cause that?

Are you sure D26 is actually changed back to 1? Because it will say that if it loses comm with the door too

We will double check it. Just seems like it a few that does it. Probably is self inflicted like most issues.

This one tac 20-03 is changing back to 1 when we go back and take a look at it. If we cycle power after doing this it changes back to disconnect.

Any other ideas?

So D26=0, then WRT. Reset the board and D26 is 1 again? Replace the CPU.
