What you should know and check for!

While not a life safety system that impacts on the effects of a fire, an Occupant Warning System (OWS) is a critical system—and the only system—that alerts occupants of a fire event within a building.

To be most effective, the operation and performance of an OWS should be in conjunction and in relation to the building's emergency evacuation plan.

The structure and type of OWS typically consists of many different components and can consist of a combination of different OWS systems. Over the last 5 years these requirements in the AS 1670 series have changed.

• The transition to AS 4428.16 Grade 2 and 3 amplified sound systems;
• When is the alert signal required, when is the evacuate signals required;
• OWS used for staged evacuation;
• OWS circuit limitations;
• Evacuation signals in Class 9a and Class 9c buildings; and
• What are the limitations of the evacuation signal under the referenced ISO 8201
