Plumbing Advisory Note
Revised June 2024
FPAA101D Fire Sprinkler Systems
Since the adoption of the 2019 National Construction Code, buildings with an
effective height of not more than 25m and a rise in storeys of 4 or more
required automatic fire sprinklers systems.
The fire sprinkler systems must comply with:
- AS 2118.1; or
- AS 2118.4, as applicable; or
- FPAA101D, except for residential care buildings; or
- FPAA101H, except for residential care buildings.
This advisory note sets out the requirements when choosing to use an FPAA101D system.
Background
FPAA101D sprinkler systems are supplied from the building’s drinking water
supply system for buildings that are less than 25m in effective height,
contain class 2 and or 3 parts and with car park facilities less than or equal
to 40 vehicle spaces. In some instances, this can be more cost effective than
installing a traditional sprinkler system (AS2118).
Each floor has a branch isolating valve that feeds both the drinking water and
sprinkler system. The sprinkler system and water supply are connected
downstream of a nontestable dual check backflow prevention device (DUAL-CV).
System configurations
Conventional – The conventional configuration uses a single branch from
the drinking water supply to feed a single sprinkler array that protects the
entire floor.
Sub metered – The sub-metered configuration requires that sprinklers
within the sole occupancy unit or area served by the drinking water sub-meters
are supplied only by that sub meter.
Note: You will need to refer to the FPAA101D technical specification
published by FPA Australia and the technical standards referred to therein for
specific installation details regarding both system configurations.
Legislative requirements
The National Construction Code Series
Volume 1 and Volume 3, refer to:
- FPAA101D Automatic Fire Sprinkler System Design and Installation Drinking Water Supply
- FPAA101H Fire Sprinkler System Design Installation Hydrant Water Supply.
Design requirements
Sprinkler systems must be designed by an appropriated qualified fire
protection engineer.
A hydraulic design submission (HDS) must be lodged with the Office of the
Technical Regulator (OTR) 2 weeks prior to the installation being carried out.
The design criteria must be hydraulically designed in accordance with
FPAA101D.
It must be installed to achieve the simultaneous water supply flow demands of
the sprinkler system and the plumbing fixtures connected to the system.
Installation requirements
The water services component of a FPAA101D fire sprinkler system installation,
including the connection from the isolation valve to fixtures, can only be
carried out by appropriately licensed plumbers.
The plumber must book an audit for the water services component with the OTR
(refer to the diagram at the end of this document).
In South Australia the installation of the fire protection component
(sprinkler head) of this system can only be carried out by an appropriately
qualified person. This is generally a registered sprinkler fitter.
The installation of the sprinkler heads is not regulated by the OTR, so this
part of the system does not need to be booked in for auditing.
Certification
The installer of the fire sprinkler pipework and fire sprinkler heads must
certify the FPAA101D Sprinkler System by completing an ESP Form 2 (essential
safety provisions).
Refer to regulation 76 of the Development Regulations 2008 or regulation 94 of
the Planning, Development and Infrastructure (General) Regulations 2017.
The form must be provided to the building owner who must then forward the
details to the relevant planning authority/council.
An online/electronic Certificate of Compliance (eCoC) must also be submitted
for the plumbing component of the system. This must be issued within 7 days of
completing the work and issued to the owner/occupier.
Building classes
FPAA101D can be used on class 2 or 3 buildings up to 25m in height or no more
than 4 storeys. Other than a residential care building.
National Construction Code definition:
Residential care building
A Class 3, 9a or 9c building which is a place of residence where 10% or more
of persons who reside there need physical assistance in conducting their daily
activities and to evacuate the building during an emergency (including any
aged care building or residential aged care building) but does not include a
hospital.
The deemed to satisfy solution for sprinkler systems in class 1 building is to
use AS 2118.5. As per NCC Vol 3 B4D3.
