Fire service installations

Fire safety installations are the safety systems required in commercial, industrial and public buildings to keep people safe in an emergency.

The requirements for the design, construction, installation, replacement, repair, alteration and maintenance of any part of a firefighting water service from the point of connection to the firefighting equipment are detailed in the National Construction Code Series, Volume Three, Plumbing Code of Australia, Part 4.0.

In South Australia, the Office of the Technical Regulator (OTR) is the regulatory authority for fire service installations. Inspections are conducted to ensure fire service installations comply with Australian and New Zealand Standard (AS/NZS) 3500.1 and AS 2419.1.

What is a fire service installation inspection?

A fire service installation inspection is where all work is tested at 1700 kPa for two hours.

After two hours, the pressure in the internal system is released through the fire hydrant or fire hose reel. The gauge must return to zero once all the pressure in the system has been released.

If the gauge doesn't return to zero, the inspection test is considered to have failed and will need to be re-booked.

An inspector from the OTR only needs to witness the last 20 minutes of the inspection test.

When the system has passed the inspection test and the OTR has received a signed Fire service installation report including lengths and materials and a completed certificate of compliance, the plumber must contact SA Water to recharge the fire service.

When an inspection is required

All new and alternations to existing fire service installations must be inspected by the OTR. Inspections are not required for metered fire service installations.
