Communication issues with Kantech Entrapass Corp Edition

[Cmarti5]

Multiple issues with system randomly not responding to cards.
Messages about communication issues and controller battery power failures.
System seems to reset when I restart computer but eventually, we're right back
to the issues.
Any idea what I need to do to fix this? Not a techi here so no clue what's
wrong or what to do.
Other messages - "Door lock device failure" , "Loop communication failure".
We had a technician out here last week who basically just shut down the system
and reset it, but the problem is back again.
We're in an industry where we cannot afford for anyone to not have access to
the building.

The board controller that handle those reader that randomly not respond to cards is bad, you need to replace it.

Hello,

I would need more information from you as to what kind of controllers you are using to diagnose.

If you are using KT400's then it is always the locks shorting out the controllers, the KT400's use wet lock supply directly off the controller, if there is a potential to ground anywhere in the line it will bring down your 485 communications loop which shares a common ground.

If your using KT300's then the same problem exists.

KT200's i believe are form C relays for locks and dont suffer from this, thus why most people say they are rock solid, in all reality the 400's installed correctly will outlast any 200.

I digress, Make sure your panels have good batteries... as this would cause loop failures. If you are using a KTNCC make sure that it is sufficiently powered using the proper rated transformer 16/40AC, and the Battery is good otherwise remove any faulty batteries.

The fact that you see lock failure, or supervision tells me it has to do with locks right off the bat. replacing faulty locks will usually fix the issue.

HES1006 locks usually fail first due to the wiring inside the keeper warming up when doors on schedule or just the tension and rubbing.

You should have a trained professional look into your issues as this cannot be fixed by an enduser no matter how tech savvy.

Watch for patterns in the Entrapass software, from the Desktops tab. We had Communication Loop Failure followed immediately by 7 of our 8 Controllers failing. We noticed this happened immediately after motion was detected as a Request To Exit on one of our Interior Doors. We disabled the Motion Detector (we did not need it anyway) and the problem was fixed.

Do you work for Kantech? We are battling a KTNCC problem at large sites with 22 or more panels split over 2 loops... your the first tech to confirm the ground fault issue... you might be able to shed some light on it
