Card Reader In

This reader is connection is essential for entering into the secure area.

The connections are for clock and data readers. This include magnetic swipe readers and proximity readers with clock and data output.
Card Reader Out ##
 Optional card reader for exiting the secure area.

The connections are for clock and data readers. This include magnetic swipe readers and proximity readers with clock and data output.
Magnetic Door Contact
 This magnetic contact (closed when door closed) monitors the status of the door at all times. For proper function of the system this contact must be fitted. It is used to detect that a card holder has not only swiped their card, but also opened the door. ie. granted acces rather than simply swiping a valid card.
Exit Button ##
 Optional device (push to make) that allows egress from the secure area.
Lock Connection
 This relay controls the Electromechanical locking device. The terminals are NC, NO and C. (ie. a changeover relay).

For 12v dc locking devices you can use the 12v dc power supplying the controller, provided that the lock does not use more than 500mA MAXIMUM.
Alarm Relay Connection
 Connect a sounder here for local alarm or use the relay to trigger another system eg CCTV control.You have a changeover relay connection. This relay will change state if either :
  1. The door is held open too long
  2. The door is opened without using a card or pressing the egress button
Intruder Alarm Connection
 If the door is the main entry door and you have an intruder alarm fitted, you may wish to make use the intruder alarm input. Making these connections will only allow access to 'Keyholders' when the intruder alarm is set. This is REGARDLESS of any access priviledges set (except Door in Free Access).
## You would not require both these options on any one-door node. ie you would normally require a card reader OR and exit button

Intruder Alarm Connection

If the door is the main entry door and you have an intruder alarm fitted, you may wish to make use the intruder alarm input. Making these connections will only allow access to 'Keyholders' when the intruder alarm is set. This is REGARDLESS of any access priviledges set.
Setting the DC2000 DIP switches
  • Each door controller needs to have a unique identification, this is achieved by setting a set of small DIP switches on each door controller. The first door controller will be set to 1 the second 2 etc.
  • This scheme enables each smart door node to reside on the same 4 wires. This numbering is known as the electronic address of the door. Below is a diagram showing the different settings for the different address:

The basic rules of addressing are ,

  • The door controller nearest the PC should ideally be number 1.
  • The next would be 2 etc.
  • The numbering must be continuous e.g. 20 doors would utilise 1 to 20 addresses.

    We say ideally, because there is no technical reason but it makes it a lot easier to understand if you number the door logically.

 
Testing the Smart Door Node

On completing the installation of a smart door node some basic tests can be carried out to establish operation prior to moving onto the next stage of installation. We refer to these tests as the, 'smart door node tests' and are detailed below.

When all connections for a single SMART Door Node are installed the 12v dc power supply can be turned on. The DC2000 Door Controller is pre-pro-grammed with a lock release time of 7 seconds.

Before proceeding you MUSTcheck the following:

  1. Lock suppressor fitted. This prevents the locking device from causing interference to the electronics in the control unit
  2. Mains earth bond connected correctly. This is covered in the section dealing with the network connections. Do not connect any earths which are also connected to 0v since this will cause data corruption
  3. 12v dc at DC2000 (Red LED on the DC2000). Fairly obvious that the controller needs power.
  4. Red LED at reader lit. This means that the local power supply on board the controller is supplying 5V to the reader.
  5. Green LED at reader flashing every 10 secs (approx.).
  6. Egress button (NORMALLY OPEN ie. push to make) releases the lock for 7 secs. The green LED on the read-er should light. At this stage you can check that the door physically unlocks and re locks correctly.
  7. Operate the egress (NORMALLY OPEN ie. push to make) button for a 2nd time. This time hold the door open. After 14 secs. (approx) the alarm relay will change state (Door held open too long). Closing the door resets the alarm relay. If an alarm device has been connected to the Alarm Relay output, to signal a Local door Alarm this can be tested also.

    Please note: that no unprotected inductive loads must be connected to the alarm relay. ie. fit a suppressor
  8. Swiping an invalid card makes the reader green LED flash 3 times. No card at this stage will unlock the door, since none have been programmed in using the PC.
  9. Write the controller serial number and door name on Master Door List

    If all is OK then remove power. Install and test the remaining SMART Door Nodes. After this has been complete we know that the control units are functioning correctly. We only now need to connect the network and test it.
