Door Control

The door control programmable function allows you to lock and unlock a door or door group based on the status of an output. It is also used for implementing fire drop (emergency egress) and lockdown states on a door or door group.

The Door Function Mode activates or deactivates the Door Control Mode based on the state of the Output to Check. The door control mode then determines what action the door or door group will take.

You can configure either continuous control (the function always checks the door state and maintains its status) or pulse control (the function only controls the door status when the output changes state).

  • Continuous modes check the door state every 30 seconds. If the state is not correct the function reasserts control and updates the door state.
  • Pulsed or edge triggered modes only change the door state at the time when the control mode changes state, and do not check or control it at other times.

Configuration

  • Door Function Mode: This field determines the control response to the output status, i.e. whether the output turns the chosen Door Control Mode on or off.

    The available door function mode options are:

    • Follow and Test Output: The door control mode continuously follows the state of the output.

      When the output is ON, the door control mode is ON. When the output is OFF, the door control mode is OFF.

    • Inverted Follow and Test Output: The door control mode continuously follows the state of the output in an inverted manner.

      When the output is ON, the door control mode is OFF. When the output is OFF, the door control mode is ON.

    • Follow Pulse On Output: The door control mode is activated on the rising edge of the output.

      When the output turns ON, the door control mode turns ON.

    • Inverted Follow Pulse On Output: The door control mode is deactivated on the rising edge of the output.

      When the output turns ON, the door control mode turns OFF.

    • Follow Pulse Off Output: The door control mode is activated on the falling edge of the output.

      When the output turns OFF, the door control mode turns ON.

    • Inverted Follow Pulse Off Output: The door control mode is deactivated on the falling edge of the output.

      When the output turns OFF, the door control mode turns OFF.

  • Door Control Mode: This field defines what action the door or door group takes when the door control mode is activated or deactivated.

    • Emulate Unlock Menu: When the door control mode is activated the door will be unlocked for the duration of the Lock Activation Time (Programming | Doors | Outputs). This has the same effect as unlocking the door via REX or credential. When the door control mode is deactivated the door is locked.

      When the Door Function Mode is set to a continuous mode, once every 30 seconds the door will unlock for its normal unlock time.

    • Latch Door Unlock: When the door control mode is activated the door will be latch unlocked. When the door control mode is deactivated the door will be locked.

    • Fire Control Door Unlock: When the door control mode is activated the door will be latch unlocked indefinitely. This command overrides other features that might be holding the door locked, such as area status. When the door control mode is deactivated the door will return to its previous state.

    • Door Lockdown (Deny Entry + Exit): When the door control mode is activated the door will be locked down and deny access to all users in both directions. When the door control mode is deactivated the lockdown will be cleared and the door will return to its previous state.

    • Door Lockdown (Allow Entry): When the door control mode is activated the door will be locked down. Access will be allowed in the entry direction only (including REN). When the door control mode is deactivated the lockdown will be cleared and the door will return to its previous state.

    • Door Lockdown (Allow Exit): When the door control mode is activated the door will be locked down. Access will be allowed in the exit direction only (including REX). When the door control mode is deactivated the lockdown will be cleared and the door will return to its previous state.

    • Door Lockdown (Allow Entry + Exit): When the door control mode is activated the door will be locked down. Access will be allowed in both directions (including REX and REN). When the door control mode is deactivated the lockdown will be cleared and the door will return to its previous state.

  • Output To Check: The output used to control the door or door group. The relationship between the output and the door control mode is determined by the Door Function Mode above.

  • Door / Door Group To Control: This door or door group is controlled by the programmable function. Door behavior is determined by the Door Control Mode above.

    Programmable functions can control either a door or a door group. If both are set only the door will be controlled by the function.
