1. Introduction

The interlock function Interlock Function in iProtect enhances security by ensuring is a crucial security feature designed to enhance access control within sensitive areas. This functionality ensures that only one door within a designated reader group can be open at a time. This feature prevents unauthorized access by restricting access to additional doors in the same group when one door is already open.any given time, significantly reducing the risk of unauthorized access. By preventing multiple doors in the same group from being opened simultaneously, the interlock function provides an additional layer of security, making it an essential tool for environments requiring strict access control measures, such as data centers, laboratories, or secure facilities.

When the interlock function is enabled, if one door in the reader group is open, all other doors in the group are automatically locked, denying entry to users attempting to access them. This feature not only protects against unauthorized entry but also aids in access management by making it evident that one of the doors within the group is currently open.

In this manual, you will find step-by-step instructions for configuring the interlock function, along with guidelines for testing and troubleshooting to ensure that the system operates effectively.

2. Required Preparations

Before activating the interlock function, ensure that the following requirements are met:

• Administrative Rights: Only system users with sufficient privileges can make changes to reader groups.

• Supported Readers: All readers participating in the interlock function must be connected to the same door controller (on the same line).

• Door Contacts: Each door in the reader group must be equipped with a magnetic door contact. This contact is essential, as it provides feedback on whether a door is open or closed. The system uses these contact statuses to determine the position

Steps to Create an Interlock Function Reader Group

Step 1: Creating a Reader Group with the Interlock Function

...

7.1.1 Configure Output and Input Connections on Line 1

• Establish Set up an additional output on Line 1 that activates whenever any door within Line 1's interlock group is open.opened.

• Specify the output type as … and assign the reader group as …

• Physically connect this output to an input on the second line ( Line 2). This setup enables configuration allows Line 2 to detect when any door in Line 1’s interlock group is openopened.

7.1.2 Create a Virtual Reader on Line 2

• In the access control software, create Navigate to Installation | Hardware | Line and locate the door controller for Line 2. Create a virtual reader on Line 2this door controller using one of the available reader ports.

• Assign the input from Line Step 7.1.1 as the door contact for this virtual reader. This configuration allows setup enables Line 2 to recognize when a door in Line 1’s interlock group is openopened.

7.1.3 Repeat Configuration on Line 2 for Two-Way Control

• To facilitate enable interlock functionality in both directions, repeat replicate Steps 7.1.1 and 7.1.2 for Line 2:

  • Create an output on Line 2 that activates whenever a door in Line 2's interlock group is openopened.

  • Physically wire connect this output to an input on Line 1.

  • Create a virtual reader on Line 1 and assign the input from Line 2 as the door contact for this virtual reader.

...

• On Line 1, establish a reader group and enable activate the Interlock Function. Include the necessary readers for Line 1, along with and also add the virtual reader located on Line 1 for monitoring Line 2. Refer to chapter 3 Steps to Create an Interlock Function Reader Group.

• On Line 2, create a similar reader group with the Interlock Function enabled, incorporating and include the virtual reader located on Line 2 for monitoring Line 1.

7.2 How

...

it works

• When any door in Line 1’s interlock group is opened:

  • The output on Line 1 activates, triggering the input on Line 2.

  • This activation signals the virtual reader on Line 2 that a door is open on Line 1, prompting the interlock function to restrict access to all other doors on Line 2.

• Conversely, if a door in Line 2’s interlock group opens:

  • The output on Line 2 activates, triggering the input on Line 1.

  • This activation signals the virtual reader on Line 1 that a door is open on Line 2, prompting the interlock function to restrict access to all other doors on Line 1.
