Hello,

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

If you are using KT400's then it is always the locks shorting out the contr=
ollers, the KT400's use wet lock supply directly off the controller, if the=
re is a potential to ground anywhere in the line it will bring down your 48=
5 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, th=
us why most people say they are rock solid, in all reality the 400's instal=
led 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 wi=
th locks right off the bat. replacing faulty locks will usually fix the iss=
ue.

HES1006 locks usually fail first due to the wiring inside the keeper warmin=
g 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.
