8. System Expansions
Up to 256 inputs can be connected to a SUPREMA system. Up to 512 alarms can be given. A
complete system for up to 64 inputs can be installed in one 19” rack. Depending on the size of
the current system already in place, various additional modules will be required to expand the
system. It must also be remembered that connecting additional modules, inputs, and relays
increases the power demand of the system and may make it necessary to choose a new
system power supply.
Attention: Any module card installed in addition must be registered with the help
of the configuration tool in the system. (see section 6.2 System Configuration).
8.1 Connection of Additional Sensors
Up to 256 sensors can be connected to a SUPREMA system.
One MAI module makes it possible to connect up to 8 sensors. An appropriate MCI or MPI
module is required for each sensor. Per rack, a maximum of either 8 MAI modules (when the
rail-mount system is used for connecting the sensors: MAT-TS or MGT40-TS module) or 4 MAI
modules (when the rack-mount system is used for connecting the sensors: MAT module) are
used; that is, a maximum of 64 or 32 sensors can be connected per rack.
The connection of additional sensors is based on the assumption that the sensors themselves
and their connecting cables have first been installed properly. The sensors are then to be
connected according to the instructions described in
section 5.6 Connection of the Sensors..
One of the following procedures must be followed, depending on the extent to which the system
has already been expanded:
1. Not all of the 8 possible inputs on an existing MAI module have been assigned. The number
of free inputs is = the number of new inputs to be connected.
In this case, only additional MPI or MCI modules (corresponding to the number and type of
new sensors to be connected) are required. To plug in the additional MPI or MCI modules, the
MAI module must first be removed from the rack. It is not necessary to shut down the system.
To avoid alarm or error messages, the inputs belonging to the MAI module
(see section 6.3.6.2
Set the Input Parameters) or the relays belonging to the inputs (see section 5.7.2.1 Relay
Inhibit) must be inhibited.
When plugging the MPI or MCI modules into the MAI module, be sure that the modules are
correctly assigned to the inputs, that the correct type of module for the sensor in question has
been selected, and that the module has been configured properly. A detailed description of
these topics can be found in
section 5.3.2 Configure the MAI Module.
After verifying that the expansions are being made correctly, plug the MAI module back into the
rack. The additional inputs must now be preadjusted (passive sensors only), configured, and
calibrated. These steps are described in detail in
sections 6.3.1 Preadjust the Passive Sen-
sors, 6.3.6 Configure the Sensors and 6.5 Preliminary Calibration.
2. All of the existing MAI modules are assigned, or the number of free inputs is < the number of
new sensors to be connected. A sufficient number of free slots for additional MAI modules are
available in the existing racks. In this case, additional MAI modules (one MAI module required
for every 8 sensors) with the associated MPI/MCI modules are required, depending on the
number of new sensors to be connected. Additional MAT/MAT-TS/MUT/MGT40-TS modules
