they must be preadjusted [passive sensors only], configured, and calibrated. These steps are de-
scribed in detail in the Installation and Start-Up Guide.
3. All of the existing MAI modules are assigned, or the number of free inputs is smaller than the
number of new inputs to be connected. No free slots for additional MAI modules are present in the
existing racks.
In this case, additional MAI modules [one MAI module required for every 8 sensors] with the as-
sociated MPI/MCI modules are required, depending on the number of new sensors to be connect-
ed. Additional MAT/MAT TS/MUT/MGT 40 TS modules will also be needed. In addition, one or
more new racks and the necessary CAN bus connecting cables are required.
Always turn off the voltage when connecting a new rack. After the supply voltage has been turned
off, mount and install the additional racks. The connection of the racks and the required configu-
ration changes [MIB module] are described in the Installation and Start-Up Guide. Be sure to
choose the correct CAN bus Bit rate and CAN node number.
NOTE: Whenever you connect additional sensors, always make sure that the voltage supply to
the system is still adequate [→ Installation and Start-Up Guide]. If necessary, install a voltage sup-
ply which meets the new requirements.
7.2 Connection of Additional Relay Driver Outputs
Additional Relay Connections
One SUPREMATouch system can provide a maximum of 512 relay driver outputs.
One MGO module makes 40 relay driver outputs available. A maximum of 10 MGO modules can
be plugged into one rack. This number, however, is based on the use of at least one additional
rack containing the appropriate MAI modules, which make it possible to connect the sensors.
One of the following procedures must be followed, depending on the extent to which the system
has already been expanded:
1. A sufficient number of free relay driver outputs are still present on an existing MGO module.
a] Until now, only the common alarms of the MRO module plugged into the rack have been used.
In this case, the MRO 8 module must be replaced by MRO 8 TS modules, which are connected
with ribbon cable via MRC TS and MUT modules to the MGO module plugged into the rack
[→ Installation and Start-Up Guide]. 5 MRO 8 TS modules, each with 8 relays, can be connected
per MRC TS module. The connection procedure is described in detail [→ Installation and Start-Up
Guide].
b] MRO 8 TS modules are already installed.
In this case, the connection can be made to existing MRO 8 TS modules; otherwise, additional
MRO 8 TS modules must be installed.
NOTE: In both cases, the relay outputs must be configured as instructed [→ Installation and Start-
Up Guide].
2. An additional MGO module is required.
a] Free slots are still available in the existing racks.
