Kit Access Door (DCD)

  • The DCD (Door Control Device) is designed to control a single access point. This device can accept inputs from most reader technology, analog alarm devices, and analog inputs from request to exit devices.
  • In the event of a computer or communications failure it will still operate and log history transactions into the memory buffer.
  • Supports Wiegand Card Reader protocols, configurable from 0-50 bits; Magstripe technologies ABA/ISO Track 2 with configurable data bits; Clock and Data, and Marlok optical key protocol.
  • Communicates using various types of supervised wiring methods including; Daisy-Chaining, T-Tapping, Home Running, Star Configuration, and High Security Loop Back.
  • Up to 100,000 DCD’s can be connected over 1000 SCU’s (Site Control Units).
  • Included in kits 135-510016 and 135-510017 (2), 064-510299 (1) and 064-510430 (1)
Model/Part #: 149-100958

Product Description

Power Requirements

  • 9-14 VDC, from our standard Power nSupply . Current consumption is 50mA nominal, and 150 mA maximum. Circuit Protection
  • Input power is protected from reverse polarity, over voltage, and transient surges.

DCD Device Communications

  • A twisted pair, multi-drop, RS-485 polling scheme is used to communicate from the DCD to the other Millenium Devices.

Dimensions

  • 4.24” x 7.35” @ < 1lb, 10.4 x 18.7cm @ < 0.4Kg

Programmable Relays

  • Each DCD employs 2 programmable Single pole, Form C relays that are rated for 2 amps @ 24 VDC.

Alarm Monitoring

  • The DCD has the capability to monitor up to 7 independent alarm inputs. 4 are supervised with 1K EOL resistors, and the other 3 are normally closed circuits. The circuit must have a break time of at least 500 ms for the alarm to trigger.

All Events History Buffer

  • 200 all events history, stored in RAM memory with a minimum of 24 hours backup.

Operating Temperature

  • 14° to 104°F (-10° to 40°C) less than 90% non-condensing humidity.

Event Buffer

  • 100 software selectable priority events (alarms, com fail, etc.). These events are stored on-board if the SCU is offline with the host computer. They can be programmed to send signals back to the computer if they are activated.

Cover Tamper

  • On-board integrated tamper switch.
