    - Mercury reader settings
      This is a complete list of Mercury reader settings; these settings correspond to specific reader hardware. Most readers in use today work on the Wiegand standard. To use smart cards or to set up Secure OSDP2 readers, refer to the specific readers' tech notes.
    - Preparing to enroll the Mercury controller
      Before you enroll the Mercury controller on the Synergis™ Cloud Link unit, you must assign a static IP address to the controller.
    - Enrolling Mercury controllers on the Synergis Cloud Link unit
      To have the Synergis™ Cloud Link unit communicate with the Mercury controllers connected to it, you must enroll them using Security Center Config Tool.
    - Configuring Mercury controller settings in the Synergis Appliance Portal
      You can configure the settings for your Mercury controllers in the Synergis™ Appliance Portal.
      - Differences between having Mercury host decision handoff enabled and disabled
        Your access control system behaves differently depending on whether the Mercury host decision handoff feature is enabled or disabled.
      - Enabling long credential support on Mercury controllers
        Before you can use credentials of up to 240 bits with your Mercury controllers, you must enable support for long credentials on your Synergis™ Cloud Link unit.
      - Configuring Mercury door forced open shunting on doors
        When Mercury door forced open shunting is enabled, the DoorForceOpenShunt timer must be set on each door in Config Tool to define how long Door forced open events are ignored.
      - Mercury native area control limitations
        The Mercury native area control, which includes interlock, max occupancy, and antipassback, has some limitations.
      - Configuring Mercury Extended grant time REX mode per door
        Before you can enable the Extended grant time REX mode on specific doors, you must create a door custom field in Security Center.
      - Database layouts for Mercury controllers
        Different database layouts are available to select for your Mercury controllers.
      - Enabling mTLS authentication on Mercury controllers
        You must enable mutual TLS (mTLS) authentication on eligible Mercury controllers added to your Synergis™ Cloud Linkunit to establish certificate-based secure communication.
      - Configuring PINs with leading zeros for Mercury controllers
        By default, Mercury doesn't support PIN credentials that start with zero. To use PINs that start with zero, you must configure the Mercury controller settings in the Synergis™ Appliance Portal.
      - Configuring Mercury controllers to not require entering # after PINs
        If your PIN is shorter than the maximum PIN length configured on the Mercury controller settings page of the Synergis™ Appliance Portal, you must press the # key after entering your PIN. To eliminate having to press the # key, you can change the maximum PIN length to match the PIN length that's most used in your system.
      - About granting access through facility codes with offline Mercury SIO boards
        Learn about how access decisions are affected when you configure access to only be granted to credentials with specific card formats and facility codes when the SIO board loses connection with the Mercury controller.
      - Configuring offline Mercury SIO boards to grant access through facility codes
        You can configure access to be granted only to credentials with specific card formats and facility codes or with specific raw card formats when the SIO board loses connection with the Mercury controller.
    - Considerations for OSDP reader installation with Mercury
      There are several points to take into consideration before adding OSDP readers to your Mercury controllers.
    - Adding OSDP (Secure Channel) readers to a Mercury controller
      To add an OSDP (Secure Channel) reader to a Mercury LP or MP controller, you must first configure the reader on the controller using Config Tool, and then pair the reader to the controller using the Synergis™ Appliance Portal.
    - Adding MR51e panels to a Mercury controller
      MR51e is a single door PoE panel that must be controlled through a Mercury controller. For the MR51e panel to communicate with the controller, you must set the MR51e panel to use either the Public DHCP (recommended) or the Static IP addressing mode.
    - Setting MR62e to use Static IP addressing mode
      Before you add the Mercury MR62e panel or Mercury controller under the Synergis™ Cloud Link unit, you must assign a static IP address to the panel.
    - Disconnecting MR panels from a Mercury controller
      To disconnect a Mercury MR panel from a Mercury controller that is enrolled in Security Center, you can delete the panel from the controller in Config Tool.
    - About Mercury triggers and procedures
      Mercury triggers and procedures are comparable to event-to-actions in Security Center. You can configure triggers and procedures in the Synergis™ Appliance Portal to run rules directly on a Mercury controller.
    - Configuring Mercury procedures in the Synergis Appliance Portal
      You must configure a procedure to define what actions to execute when a trigger event occurs.
    - Configuring Mercury triggers in the Synergis Appliance Portal
      Configure a trigger to define when a procedure is run.
    - Disabling Mercury triggers and procedures in the Synergis Appliance Portal
      To prevent a procedure from being run, you can disable the trigger that the procedure is linked to.

Configuring Mercury door forced open shunting on doors

2026-04-15

When Mercury door forced open shunting is enabled, the DoorForceOpenShunt timer must be set on each door in Config Tool to define how long Door forced open events are ignored.

Before you begin

Ensure the following:

The Inhibit 'Door forced' open event setting is enabled on the Mercury controller setting page of the Synergis™ Appliance Portal.
The Mercury controllers meet the following minimum version requirements:
- EP controllers require firmware version 1.29.x or later
- LP controllers require firmware version 1.30.7 or later
- MP controllers require firmware version 2.1.0 or later

What you should know

When the Mercury door forced open shunting feature is enabled, Synergis Softwire automatically creates the DoorForceOpenShunt door custom field in Security Center, which is used as a timer configured per door. When the timer value is above zero, the timer restarts every time the door closes.

If the Mercury door forced open shunting feature is enabled and then disabled, the DoorForceOpenShunt timer remains visible in Config Tool, but changing the value won't affect anything.

Procedure

From the Config Tool homepage, open the Area view task.
Select the door you want to configure, and click the Custom fields tab.
In the Mercury door mode section, enter a value in seconds for DoorForceOpenShunt.

Note:
When the value is set to 0 or lower, the feature is disabled on the door. The default value is 0 and the maximum value is 65,536.
Click Apply.
