4 Standard applications
The principal field of application of XC1003-A is room protection. Two different
system topologies are used:
–
Centralized
–
Modular
4.1 Centralized installation
Centralized systems consist of a single set of cylinders placed in a storage area.
Pipe and nozzles are used to transfer the gas from the cylinders to the protected
room. A single actuator (electromagnetic or pyrotechnical) triggers a pilot cylinder
which then activates others cylinders by pneumatic activation. Two pilot cylinders
may be used in some countries when activation redundancy is required. In that
case, two electromagnetic solenoids are connected in parallel to the monitored
control output 4 (or 5 if selected), or two pyrotechnical actuators are connected in
series to the monitored control output 4 (or 5 if selected).
