Dual Door Controller (DDC) - AV-iQ
Dual Door Controller
(DDC)
The Dual Door Controller (DDC) is an access control field device for MDI’s Integrated
Digital Controllers. The DDC functions as a door interface for the Network Local
Controller (NLC)/Network Communications Board (COMM), integrating card readers
and associated door hardware into a single package. The unit is configurable for two
doors with entry readers or for one door with entry and exit readers.
The DDC memory stores
20,000 card records. All
access control decisions for
its two readers are made by
the DDC using this
database. Cards that have
not been used for a preset
number of days are
removed from the DDC
database and replaced with
more active cards.
When a card’s record is not
found in the DDC database,
the card data is passed to
the NLC for the access
control decision. If
communication between the
DDC and NLC/COMM is
disrupted, the DDC
continues to make access
decisions for its 20,000 cardholders. Up to 512 events are stored at the DDC and passed
to the NLC/COMM when communications is restored.
Security Suite Hardware
Features
• Supports 2 doors with Entry Readers or
1 door with Entry/Exit Readers
• Each reader port has connections for
power, data, 2 LEDs and Buzzer
• Supported readers include Magstripe,
Wiegand, Barcode, Proximity,
Biometrics, and SmartCard
• Supports industry standard and custom
card formats
• Stores 20,000 cardholder database
• Access decisions are made at the DDC
using local database, even during loss
of communication with NLC/COMM
• Stores 500 events
• Access decisions are made at NLC
when card not found in DDC database
• Inactive card records are removed from
DDC database and replaced with active
cards
• 4 Supervised inputs: 2 door monitor and
2 alarm inputs
• 8 Non-supervised inputs: 2 Request-toexit (REX), 2 tamper and 4 Auxiliary
inputs
• 6 Form-C output relays (3 per door):
door lock, alarm and spare
• Accepts 6.0 - 16.0 Vdc power source
• Downloadable FLASH MEMORY
eliminates the need to change EPROMs
for applications programming and
system upgrades RS-485 bus remote
installation up to 4,000 feet (1300m)
from NLC/COMM
The DDC features 2 reader ports, flexible input and output configurations, FLASH
memory for application programs (firmware) and SDRAM for cardholder database and
event storage. The interface between the DDC and NLC/COMM utilizes industry
standard RS-485 communications protocol that allows the DDC to be located up to
4,000 feet from the NLC/COMM.
The DDC is configured with a diagnostic port which allows field service and other
technical personnel to view activity, perform diagnostics analysis, and make some
configuration changes.
