Answer:
The controller connects to access readers or push switches across four dedicated channels (SW1, SW2, SW3, SW4) and accepts emergency manual override push buttons via the dedicated EMG terminal.
The eSSL KTI01003001DR04 interlocking unit provides segregated connection points for up to four entry points. Each door channel (SW1 through SW4) accepts input signals from standard door-release push buttons or access control readers.
In addition to standard door station inputs, the controller incorporates a dedicated EMG terminal designed to interface with manual emergency override push buttons or break-glass units, ensuring all doors can be released simultaneously during life-safety events.
