T26 System Manual Part 1: Installation
2.1.5 Installation Tip: Replacing an Existing Doorbell by a T26
The MOBOTIX DoorStation, in particular the version with integrated Mx2wire+ technology
(for network connection with simultaneous power supply via the same two-wire cable), is
an ideal retrot solution that is very easy and quick to install.
The following two installation steps are normally all that is required to replace an existing,
simple doorbell with a complete T26 set including a MX-DoorMaster:
Step 1: Connect the T26 Using a Two-Wire Cable
Disconnect the doorbell from power (by disconnecting the bell transformer), then remove
it. Connect the wire pair to the Info Module Mx2wire+ (T26 is mounted directly above the
cable). This wire pair is conducted directly to the electrical cabinet, from where it is connected
to the power supply and remote stations via the Mx2wire+ indoor unit.
