Alarm Controller for Industrial Cabinets

SDD ITG has developed an alarm controller based on RFID technology, dedicated to access control to
industrial cabinets.

Working principle is simple. System detects opening of doors of the cabinet. It then leaves certain period
of time for a user/serviceperson to authenticate himself/herself, waiving his/her RFID card to the RFID
reader,   integrated   into   the   controller.   By   default,   user   has   30   seconds    to   authenticate,   time   period
duration is settable.

When      user’s   card   is  detected,    controller   verifies  user’s   access     rights  and   based     on  the   result  of
verification it will activate the alarm, if necessary.

If user’s authentication   was successful, controller switches to authorized mode and  user/serviceperson
can work freely for certain period of time (30 minutes by default).

Otherwise, if user doesn’t have right to access the protected content, controller will switch into the alarm
mode   and   the   sound   alarm   will   be   activated   and   alert   message   will   be   sent   by   e-mail   and/or   SMS   to
central control station.

Alarm   mode   can   be   ended   at   any   moment   by   placing   valid   ID   card   in   front   of   the   RFID   reader.   Also,
closing door of the cabinet will end the alarm mode after one minute of time.

Communication with the central control station is conducted over Ethernet. Device has one IP address
and two communication ports. One is used for setting of and readings data of the device itself and the
other one for downloading data log.

Controller reports on each of the following events: opening/closing of the door, successful / unsuccessful
authorization attempt, alarm mode started/ended.
