Defining Door Contact Options

In most applications, the low cost door contact is the only supervisory element that protects the investment made to control access to the door. The door lock and card reader (or keypad) provide security and prevent unauthorized entry only when the door is closed and locked. A simple door contact allows the ability to monitor several door conditions such as: door forced open, door open too long, interlock options (mantrap), etc.

  1. In the Door window, select the Contact tab.
  2. Select the door contact from the Door contact list.
  3. In Shunt Door Schedule, select a schedule.
    Note: A door contact cannot be assigned to more than 2 readers.

    This feature allows associating a schedule to a door contact in order to bypass the events / alarms related to the door contact supervision. If no schedule is selected, the system will continue to work as usual. If a valid schedule is selected, the system will hide following conditions in the events monitoring desktop:

    • Door Forced open
    • Door forced open restored
    • Door open too long (unless otherwise indicated)
    • Pre-Alarm door open too long
    • Door left open
  4. Check Enable door open too long notification to continue to receive the Door open too long event and the Pre-Alarm door open too long in the desktop. If there is no schedule selected, this checkbox is not available for selection (greyed out).
    Note: For KT-200 Controllers, Input 1 (door contact) and 2 (request to exit device) are ideally reserved for Door 1 of the controller whereas Input 9 (door contact) and 10 (request to exit device) are ideally reserved for Door 2 of the same controller. The input that is used for the door contact or REX contact SHOULD NOT have a “monitoring” schedule defined in the “Input Definition” menu.
  5. Check the door reading options:
    • Door open reading : If selected, this option allows the system to read cards while the door is open. However the system will not unlock the door if it was locked. If selected, the event “Access granted” is generated. Otherwise, the event “Access granted - Door open” is generated. Default is checked.
    • Door unlocked reading : If selected, this option allows the system to read cards while the door is unlocked manually by the operator or by a valid unlock schedule. If selected, the event “Access granted - Door unlocked” will be generated on access. To ignore all access events while the door is unlocked, leave this option deselected. Default is checked.
    • Unlock on access door opened: If selected, this option allows the system to unlock access on door opened at any time. Default is unchecked.
    • Pre-alarm door opened too long : If selected, this option allows the system to generate the event “pre-alarm door open too long” and sound the door piezo when half of the delay defined in the Open time field is expired. It will continue to sound until the door is closed. Default is unchecked.
      Note: If the door is a KT-400 and if the value entered is higher or equal than the open time and if the checkbox is selected, a pop up will appear explaining that the delay value is incorrect. Value range can be between 00:00:01 and 18:12:15 and must be lower than the door open time.
  6. Select the appropriate Relock on access option. You may choose to relock an access On door opening or On door closing. Default value is On door opening.
