1 Contents Scope of Section 2 Application Issues AS vs 2005 Schedules & Log- Books

2 Scope of AS1851 Section 2 Review and rewrite of all sprinkler maintenance activities AS becomes General Systems CL Informative appendices become stand-alone systems:- CL Residential and Domestic systems CL Dry Pipe systems CL Deluge & Water Spray systems CL Pre-Action systems CL Tail-end systems treated as above CL Drencher systems

3 Scope of AS1851 Section 2 Combined systems, AS 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 maintenance requirements are in Section 3 Fire Pumpsets

4 Application Issues documentation Pressure gauge schedule:- Benchmark for pass/ fail records Water supply pressures Pump delivery at closed head High & low system pressures Pump start pressure switches Max & min tolerances for pass/fail Block plan upgrade:- Benchmark to conduct survey AS2118 revised and more specific to align with survey requirements

5 Application Issues Monthly Testing Many routines (now activities) and their frequencies have now altered Weekly testing of sprinkler systems may be omitted where:- Facilities to prevent false alarms & unnecessary brigade call-out Similarly, weekly testing of fire pumpsets may be omitted where:- Monthly test savings help off-set new compliance survey & interface test

6 Application Issues Monthly Testing Many routines (now activities) and their frequencies have now altered Weekly testing of sprinkler systems may be omitted where:- Facilities to prevent false alarms & unnecessary brigade call-out Similarly, weekly testing of fire pumpsets may be omitted where:- Monthly test savings help off-set new compliance survey & interface test

9 Application Issues Tolerance & Defects Maintenance date frequency tolerance requires use of past anniversary date Future visits outside tolerance are considered as a missed test Service provider to advise when aggressive environments apply Detailed defect process:- Critical defects reported within 24hrs and advised to rectify minimum delay Non critical defects reported within week & advised to repair within month System re-test following rectification

10 Application Issues Tolerance & Defects Maintenance date frequency tolerance requires use of past anniversary date Future visits outside tolerance are considered as a missed test Service provider to advise when aggressive environments apply Detailed defect process:- Critical defects reported with-in 24hrs and advised to rectify minimum delay Non critical defects reported with-in week & advised to repair within month System re-test following rectification

11 AS vs AS New Weekly * Monthly Six Monthly Annual functional test (flow test) Annual interface test Annual survey Annual condition report 3 Yearly (prevent maintenance) 12 Yearly sprinkler sampling 24/6 Yearly sprinkler sampling Current Weekly Quarterly Annual functional test (flow test) 3 Yearly (prevent maintenance) 24/6 Yearly sprinkler sampling.

12 AS vs AS Monthly:- 15mm functional test every system, however only one brigade alarm required All alarm initiating devices to be tested including new DBEP strobe Rotational testing when 12 or more alarm devices, with all tested within 3 months Operate and record number of all valves Test all pump start devices to max of 5 starts, with rotational testing all within 6 months Six Monthly:- 50mm main drain water supply test Floor/zone indication flow switches All underground & subsidiary valves & anti-tamper switches, record number valves.

13 AS vs AS Annual:- Water supply flow test, using master gauges and subject to Water Agency limitations Pressure reducing station including relief valve Remote sprinkler test valve alarm device 3 yearly:- Preventative maintenance valve overhauls and water supply tanks with 12 year drain and clean requirement Sprinkler Testing:- Dry sprinklers 12 yrs & recommend replace Fast response sprinklers 12yrs 12yrs 6yrs with additional ISO RTI test at 12yrs All other sprinklers 24yrs 6yrs. Multiple Jet Controls 30yrs 12yrs

14 AS Additional Items Annual functional system test:- Via sprinkler pressure or flow switch verify that the interface to other fire systems functions to the building s system interface schematic. Planning to limit interruption: Planning to limit interruption:- Single test coordinator (building owner) occupant advice notice prior to test Interface schedule:- Establish from commissioning & site data plant shutdown, HVAC, EWS, roof vents, door release,etc.

15 AS Additional Items Annual system survey:- Establish that the system is capable of performing to the standard of which it was originally required to achieve Conducted from floor level and intended to identify changes to the sprinkler system, or the building and its environment, that would impair the performance of the sprinkler system. Intended to identify any changes in hazard classification or storage practices, which may necessitate corresponding changes in sprinkler installation design, layout or site block plans and schedule

16 AS Additional Items Annual condition report:- Required to be prepared to provide evidence of compliance with AS1851. Signatory is responsible for report and for providing all supporting records. Any work provided by others must be fully documented and signed. Supported by copies of monthly IT&M reports, defect repairs & work by others Acknowledge all missed tests and any outstanding defect rectification required With the system survey provides the basis of BCA annual compliance

17 Schedules and Log-Books Schedules:- Separate Inspection-Record and Test-Record schedules Normally performed simultaneously and recorded in the one logbook Also facilitates weekly inspection and monthly testing if desired. Definitions of Inspection visual examination of component. Definition of Test confirmation of correct function or performance Tests measured, recorded, then noted as pass or fail against benchmark

18 Schedules and Log-Books Log Book:- FPAA log-books provide AS1851 compliant record & defects report CL Maintenance records may be electronically based, but hard copy records shall be kept on site and be available at all times CL logbooks (in the case of sprinkler, pump-set, fire hydrant, detection, smoke and heat alarm, fire alarm monitoring, sound, intercom, gaseous, aerosol, water mist, passive fire and smoke and HVAC and evacuation systems

19 Sustainable Water Use Strategy Remote Sprinkler Annual 240 litres Diesel Pump Run Test Weekly 3,000 litres Electric Pump Run Test Weekly 900 litres Flow Switch quarterly 40 L/switch Diesel Pump Load Test Quarterly 40,500 litres Electric Pump Load Test Quarterly 13,500 litres Supply Flow Test Annual 7,000 litres Control Assembly Weekly 80 litres Water Usage Sprinkler and Water Supply Fire System Testing

20 Sustainable Water Use Strategy AS will reduce annual system testing water use by approx 75% Due to a change to monthly test frequency, type of test & method of test Based on OH group III & HH 10mm density with 800kPa town main supply Greatest need is high rise building with diesel & electric pump dual supply
