QEII K Block Fire Occupant Warning System (OWS) Replacement/Upgrade — Contract awarded to Ascent Fire Pty Ltd
Awarded 28 Apr 2026
About
North Metropolitan Health Service awarded a contract to Ascent Fire Pty Ltd for the replacement and upgrade of the Fire Occupant Warning System (OWS) in K Block at QEII.
The award followed reports that during monthly testing and a fire alarm the existing OWS had faults that caused an evacuation: the OWS intercom only operated in the new tunnel area and there were no speakers through the remainder of the building, and the system was not monitored due to its original configuration.
The contract covered a complete K Block OWS replacement/upgrade and specified works that included installation of a full speaker OWS system to all floors; installation of horns to the sub-basement and horns/strobes to plant rooms; installation of speakers to achieve building-wide compliance; installation of OWS amplifiers and increased battery size; and surface-mount style speakers for all locations.
