In an intercom bypass wiring scenario with a single pair from the MTR, you would need to install a Bypass Module in the suite. A bypass module allows for the intercom system to be connected with other devices without interrupting the signal flow. It essentially bypasses the intercom system, allowing for seamless communication.
