To enable interlock functionality in both directions, 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 opened.
Physically connect this output to an input on Line 1.
Create a virtual reader on Line 1 and assign the input as the door contact for this virtual reader.

On Line 1, establish a reader group and activate the Interlock Function. Include the necessary readers for Line 1, 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, 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 which in turn triggers the input on Line 2.
- This activation signals informs 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 within the interlock reader group on Line 2.
Conversely, if a door in Line 2’s interlock group opensis opened:
- The output on Line 2 activates, triggering which triggers the input on Line 1.
- This activation signals informs 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.
