1. Introduction
The Interlock Function in iProtect is a crucial an essential security feature designed to enhance access control within sensitive in secure areas. This functionality function ensures that only one door within a designated specified reader group can be open at any given time, significantly reducing the risk of thereby preventing unauthorized access. By preventing restricting the opening of multiple doors in the same group from being opened simultaneouslya group, the interlock function provides an additional layer of security, making it an essential tool for environments requiring strict access control measuresparticularly valuable for locations with stringent access requirements, such as data centers, laboratories, or secure and high-security facilities.
...
When the interlock function is enabledactivated, if one door in the reader group is open, all other doors in the that group are will automatically locked, denying entry to users attempting to access them. This feature not only protects lock, and the LEDs of the other readers will blink red and green. This configuration not only safeguards against unauthorized entry but also aids in access management by making it evident that clearly indicates when one of the doors within in the group is currently already open.
In this manual, you will find This manual contains detailed step-by-step instructions for configuring setting up the interlock function, along with guidelines guidance for testing and troubleshooting to ensure that the system operates effectively.
2. Preparations Required
...
Before activating turning on the interlock function, ensure that make sure the following requirements are met:
Administrative Rightsrights: Only system users with sufficient privileges can make changes to proper access rights can adjust reader groups.
Supported Readersreaders: All readers participating in the interlock function group must be connected to the same door controller (and be on the same line).
Door Contactscontacts: Each door in the reader group must be equipped with have a magnetic door contact. This contact is essential, as it provides feedback to the system on whether a door is open or closed. The system uses these contact statuses to determine the position, which is needed for the interlock function to work.
Deadbolt contact (optional): When using a reader configuration with both a door contact and a deadbolt contact, both contacts should be idle (door closed and locked) for the interlock function to be inactive. If either contact becomes active, the interlock function is triggered. As a result, other doors in the group will blink and reject access until all contacts return to idle.

Since iProtect version 10.04, the interlock function can be set up across multiple lines. See Chapter 7. Configuring the Interlock Function Across Multiple Lines for details. |
3. Steps to Create
...
a Reader Group with the Interlock Function
...
Step 1:
...
Create the Reader Group
...
Navigate Go to the Readergroup Reader Group menu located at under access | settings | readergroupreader group.
In the tree - view, right-click and then select add new readergroup. Assign a descriptive name, such as "Interlock Group 1".Enable select Add Reader group. Give the group a logical name, like “Interlock Group 1.”
Turn on the Interlock Function by checking the corresponding Interlocking Reader group checkbox. This function ensures that only one door within the in this group can be opened open at any given a time.
By default, the option operator must follow the rule is activated. If this checkbox is unchecked, the doors in this group can be controlled by an iProtect system operator (or through an API connection) without the interlock restriction.
Step 2: Adding Readers to the Reader Group
...
| Info |
|---|
The setting “operator must follow interlock rules” is off by default. If unchecked, an iProtect operator or API user can control doors in this group without interlock limitations. |
Step 2: Add Readers to the reader Group
Click on the + sign next to the newly created reader group to display the reader list.
Select the reader list in the tree-view; a detailed form will appear with a search box for the reader list.
Add the readers that who should be part of included in the interlock functiongroup by checking the boxes next to the desired readers. Ensure that all selected readers are connected to on the same controller.
Confirm the selection your selections and save the changes.
4. Testing and Validation
To ensure check that the interlock function operates correctly, follow these stepsis working correctly:
Open one of the doors within a door in the reader group and try to open another door. Access should be denied for The system should block access to any other door doors in the group as long as while the first door remains is open.
Close the first door and check if confirm that the other doors in the group are can now accessiblebe opened.
Repeat the above two these steps for all the doors in the interlock group.
...
When the interlock function is active, the readers provide visual feedback to indicate the status of doors within the interlockshow door status:
If one door in the interlock is open, all other readers in the group will blink red/green. This flashing pattern informs users that a door in the interlock is currently open and , letting users know that access to other doors is temporarily restrictedblocked.
6. Troubleshooting the Interlock Function
If the interlock function is not operating doesn’t work as expected:
Check Door Contacts:
...
Make sure magnetic door contacts are
...
working correctly, as the system needs them to detect door status.
Verify Configuration:
...
Review the reader group configuration to
...
ensure all settings are correct and
...
all readers are assigned to the correct
...
group.
7. Configuring the Interlock Function Across Multiple Lines
With iProtect version 10.04, it is now possible to extend the interlock function can work across multiple lines. This feature allows , allowing doors on different lines to be linked in a shared share an interlock group , ensuring that access is restricted across lines whenever a door within the group and block access when any interlock group door is open.

7.3 Testing the Multi-Line Interlock
...
To ensure confirm that the multi-line interlock function operates effectively in both directionsworks:
Open a interlock door on Line 1 and verify that the corresponding output/input connection triggers the virtual reader on Line 2confirm the Line 2 virtual reader is triggered.
Open a interlock door on Line 2 and check that the output/input connection activates the virtual reader on Line 1.Attempt access on confirm the Line 1 virtual reader is triggered.
Try accessing other doors on each line while a door in the opposite line’s interlock group on the other line is open to confirm that access restrictions are enforced as expectedproper restrictions.
By mirroring the setup on each lineWith this setup, the interlock function guarantees that will restrict access is restricted across all connected lines as expected, regardless of no matter which line has an open door.

Event ID | Event name | Error message | Description | Is generated by |
|---|---|---|---|---|
3 | Subscriber card: no access | No access, other interlock door is open | Access denied because another interlock door is open. | Occurs when an access request is made at a reader with blinking red/green light, indicating an open door. |
9. Frequently Asked Questions (FAQ)
Q: Why are the readers flashing red/green?
A: This indicates that means a door within in the interlock group is open or not locked, and so the system is preventing blocking access to other doors within in the same group.
