WHAT DOES AS2941 SPECIFY?

In General:-• Foreword:

• provides minimum requirements for FIRE pump sets• Based on sound engineering principles, test data and field experience

• Scope:• Totally independent pump set systems• Specific requirements for pumps, drivers, pump controllers and auxiliary

equipment for FIRE pump sets• Requirements for installation and acceptance testing for electrical and

compression-ignition drivers


WHAT DOES AS2941 SPECIFY?

Specifically:-• Sections 3 & 4 – Pumps • Section 8 - Electric Motors & Controllers• Section 9 – Diesel Engines & Controllers• Section 3 – Pipework• Section 10 - Shop Testing & Conformance• Appendix D – the Pump House/Room• Appendix F – Performance Test Data, Controller Function Test - Typical


WHY DO WE NEED AS2941?

A very good Question!Why do we need any standard?

We need AS2941 so that we can be confident that the fire pump set will do its job effectively in the event that it is required to run to

protect life and property from a fire.


WHO IS RESPONSIBLE FOR ENSURING COMPLIANCE WITH AS2941?

Architects:• Section 11 & Appendix D state clearances required around fire

pumps for maintenance and replacementEngineers & Designers:• Section 2 Water Supplies, Section 3 General Requirements, Section 4

Specific Requirements and so onPump Set Manufacturers:• Among other sections, Section 10 Shop testing & Conformance


WHO IS RESPONSIBLE FOR ENSURING COMPLIANCE WITH AS2941?

Fire Contractors:• All SectionsCertifiers:• All SectionsBuilders:• All SectionsFacilities Managers:• All Sections


WHAT GUARANTEE DO YOU HAVE FOR COMPLIANCE?

Are the words:Certificate of Conformance

“This is to certify that the ABC Pump Company electric fire pump serial number XYZ123 built and tested on factory order 12345/1 complies with the requirements of AS2941-2013”.

Sufficient?



Performance to AS2417 Annex A

Annubar line take-off between non-return valve & discharge isolation valve – NOT from common discharge manifold



Maximum Absorbed PUMP

WHAT DOES COMPLIANCE LOOK LIKE?


WHAT DOES NON-COMPLIANCE LOOK LIKE?


WHAT DOES NON-COMPLIANCE LOOKLIKE?



Electric Panel8.2.4e – is capable of being locked in the ON position (power on)8.2.8 – touch screens shall not be used for primary operation – start, stop & reset8.2.19 – each driver control device and each switch and circuit breaker shall be marked to indicate plainly the name of the manufacturer, model number and applicable electrical rating



Diesel Panel9.3.6.5 – Manual shutdown shall be accomplished by means of a hold-on push button manual stop switch9.4.4 – is capable of being locked in the ON position (power on)9.4.6 – touch screens shall not be used for primary operation – start, stop & reset9.4.21 – similar wording to 8.2.19 regarding labelling.



Power cables must be a minimum of 300mm above the floor

Incorrect gauge installation

No isolation valve

downstream of mains

bypass check valve &

pipework is unsupported placing high

stress on pump

nozzles

Pressure switch loop is unsupported

– no vibration isolation



Both the main cooling line and the bypass cooling line must contain a pressure regulating valve – not

one for both

No check valve downstream of the bypass strainer

Stress on hose – poor manufacture

only


A CHECK LIST

In our experience, compliance with the standard is poor!

The possible solution?“Check List?”


A CHECK LIST


SUMMING UP - THE ISSUES

Who would complete a check list?We see the document being the responsibility of numerous individuals.Perhaps it should be split or sectioned for the following:

• System Designer• Pumpset Manufacturer• Installation Contractor

• Certifier• Building Surveyor
