MORPHO DOCUMENT – REPRODUCTION AND DISCLOSURE FORBIDDEN
SSE-00000XXXXX-01
September 2013
The individuals who are authorized to access the secured area have their User ID
listed in a so-called "White List" (in contrast with a black list).
The MorphoAccess® Sigma Series terminal and the Controller are communicating
according to one of the TCP/IP, Wiegand, Dataclock or RS485 protocols:
 The MorphoAccess® Sigma Series terminal sends User ID to the Controller
 The Controller sends its decision to the MorphoAccess® Sigma Series terminal
(which displays GREEN light if access is granted or RED light if denied)
 The MorphoAccess® Sigma Series terminal sends an alarm signal to the Controller
as soon as a malicious operation (terminal pulled out from the wall or having its
bottom cover opened out of maintenance operations) is detected; refer the
paragraph dealing with anti-pulling and anti-tamper switches for more
explanations.
The Controller is part of the global Access Control System of the secured area, which
for instance can administrate the White List of the Controller and receive diaries of
the decisions taken by the Controller.
An Alarm (3rd party product)
This element is connected to the MorphoAccess® Sigma Series terminal through a dry
contact.
The MorphoAccess® Sigma Series terminal sends the command to activate the Alarm
as soon as a malicious operation (terminal pulled out from the wall or having its
bottom cover opened out of maintenance operations) is detected; refer the
paragraph dealing with anti-pulling and anti-tamper switches for more explanations.
A Door Electric Latch or equivalent (3rd party product)
This element once activated opens the access. The Controller is the one which sends
the command to activate the latch if access is granted (i.e. if the individual's User ID is
listed in the Controller White List). Connection between these two elements is done
through a dry contact.
