•Schedules & Log-

•Review and rewrite of all sprinkler maintenance activities
•AS 1851.3 1997 becomes “General Systems” CL 2.4.1
•Inform
ative appendices become stand-alone systems:-
–CL 2.4.2 Residential and Domestic systems
–CL 2.4.3 Dry Pipe systems
–CL 2.4.4 Deluge & W
ater Spray systems
–CL 2.4.5 Pre-Action systems

•Combined systems, AS2118.6 clarified & aligned:-
–Utilise General systems (table 2.4) & Hydrant systems
(table 4.4)
–As a combined water supply, also Fire Pump (table 3.4)
–All sprinkler, hydrant and pump sections are aligned
•Pump-set maintenance schedules integrated:-
–Previously in AS 1851, sprinklers omitted pumps,
hydrants retained pumps, while fire pumps also had
their own section
–Now, pump starting devices are included in each system
section
–Pump m
aintenance requirements are in Section 3 Fire
Pumpsets
