2.5 Installing the MX-DoorMaster
2.5.1 Overview of Connectors
The MX-DoorMaster is connected to the door station via the MxBus two-wire cable and the
two wires of the the protection cable.
In addition, the four cables of the door signal contacts and the two cables of the electrically
operated door opening components (standard door opener, electronic lock) can also be
connected to the MX-DoorMaster (see «Technical Specications» in Section 1.2).
The main function of this innovative device is to control the door opener in a tamper-proof
manner and record the status of the door (open, closed, closed and locked). The MX-DoorMaster,
with its speaker that can be switched o, also functions as a doorbell. It furthermore allows
the door to be opened using a button and controls the the protection in the T26 housing.
Thanks to its built-in batteries, which are kept fully charged via the MxBus cables, the
MX-DoorMaster is able to power both the access module in the outdoor station and a con
-
nected door opener for several hours in the case of power failure, therefore ensuring that
the door can still be accessed without a key.
