a) This system is suitable for storage in environmental conditions from -20° to +50°C.
b) System pressure is specified as 200 bar @ 20°C
c) If this fixed gaseous fire extinguishing system is used with existing pipework (so called drop-in systems) it is the responsibility of
the installing company to ensure that:
- all pipework can withstand system pressures and will be safe during operation;
- all pipework meets the requirements of the gas system manufacturers design manual; and
- all applicable legislation is complied with.
