m1kam + essex Wrong code?

[jchulick]

I have my M1KAM hooked up to an Essex keypad to control a mag lock.  Everything is working as it should.  Question - is it possible to log wrong codes or execute a rule when a wrong code is entered?
 
Thanks!

Possible, yes, but in practicality you would need to put every weigand code possible into the M1, as the Essex only passes through the data to the KAM. Only way I could see this possible would be IF the wrong # keypresses is set in RP, but that's a stretch since the Essex units typically only pass through the data once enough bits are entered to complete the 26 bit stream (after the site code, etc) or after entering the # key (depends on your unit and how you wire it.....)

Thanks - I was only interested in capturing / actioning after a code was submitted (after # in my setup).  In looking at the ELK logs it doesnt appear that there is any record of invalid codes.  So I am guessing the M1KAM doesnt keep or do anything with codes that dont match an enrolled user.  So other than creating a record for every possible combination there is no other option for log gin access denied or executing a rule.

The Essex is only a passthrough...the site code will always be transmitted, with the variable being the physical code, which is no different than a card # on a prox card....actually, if you had a prox card with the same site code and credential #, you could install a 26 bit reader and that would work the same as entering in the code on that physical keypad. Probably not a concern, but a FYI.
 
In the M1's case, the calculator they have figures the card offset and to me, without really caring too much to look deeper, appears to provide the values with the offset into HEX for the M1 to be able to recognize..
 
The KAM only changes the weigand to a stream on 485 that is passed through to the M1 for the decision to execute a rule, nothing is resident on the KAM.
 
I suppose you could also try a "wrong keypress" lockout, but that might shoot yourself in the foot with physical M1 keypads.
