As the National Broadband Network (NBN) rolls out across South Australia, existing fixed line networks are being progressively disconnected. Monitored fire alarms and lift phones operating over these networks may cease to operate unless they are migrated to an alternate network.

Disconnection of almost all fire and lift services from the legacy copper network, including emergency lift phones and monitored fire alarms, will occur shortly after 18 March 2022. For these services to keep working, fire and lift companies, businesses, government entities, building and strata managers, body corporates and private users must take action to migrate to an alternative network before 18 March 2022.

It is crucial that any lift phones or monitored fire alarms that are still connected to the legacy copper network are migrated to an alternative technology (such as a mobile network or the NBN network with a mobile network fall-back) before 18 March 2022 to keep them working.

Work Health and Safety legislation requires an operational communication system for monitored fire alarms and lifts.

Monitored fire alarms and lift phones are safety-critical services and there are serious public safety, personal injury and property damage risks if they fail to operate in an emergency situation. Migration of these services to alternate telecommunications networks does not happen automatically.

It is important to note that equipment connected over the NBN will cease to work during a power outage and an alternative backup power source should be discussed with your provider.

Building owners and managers are responsible for ensuring obligations are met for the operation of monitored fire alarms and lift phones under the relevant building codes and standards. Further information is available in the Migration of monitored fire alarm and lift phone services good practice guide.
