The diagram below shows jumper connections for a typical master/slave connection between two modules in separate
chassis. The master module is shown in chassis 1, slot 4 and the slave module is in chassis 2, slot 6. If a critical fault occurs in
the master module, its relay signal is carried via the jumpers, from the chassis 1, slot 4 ALARM OUT terminal to the chassis 2,
slot 6 ALARM IN terminal. This turns on the slave module located in chassis 2, slot 6. The slave module continues in
operation until the master module is fixed. At that time, the master module automatically takes over and the slave module
switch relay turns off.
