All inputs/outputs, except output D, are monitored by the module itself. The power
supply is provided by the first and the last XC1003-A control unit.
Input A:
- used to connect the "loss of agent" monitoring devices (manometers, weighing
device) from the main cylinder bank as well as from the pilot cylinder
- « Loss of agent » information as well as electrical fault (break or short circuit) on
the line is forwarded, via output D, to all the extinguishing control panels in
order to display « Loss of agent » or « General fault » (line fault)
Output B:
- used to connect the control cylinder actuator
- redundant so that an electrical fault (break or short circuit) on one line doesn't
affect any extinguishing process
- controlled by reverse polarity lines
- electrical faults (break or short circuit) are forwarded, via output D, to all the
extinguishing control panels in order to display « Actuators fault »
Input C:
- receives the information that at least, one extinguishing control panel in the
network is activated
- on receipt, the module transmits, via output D, the blocking information to all the
extinguishing control panels in order to display « Actuators disabled »
