Medical alarm devices running on copper phone lines will stop working unless they are transferred to the National Broadband Network, NBN Co says.
The company announced a register on Friday to identify households with medical devices which may need extra assistance making the switch to the new network.
Alarms and devices running on the copper lines are not automatically transitioned.
When the national copper line switch off begins in 15 communities on May 23, devices not migrated to the new NBN infrastructure will stop working.
People who rely on medical alarms have been urged to contact their preferred service provider as soon as possible, as have businesses which rely on security alarms.
Nan Bosler, President of the Seniors Computers Clubs Association, urged people who use a medical alarm to begin the transition process now.
“I would also advise seniors to use this as an opportunity to get themselves online and experience the benefits of fast broadband,” she said.
Services affected by the copper disconnection include landline phones, ADSL and Telstra cable internet services, fire alarms, medical alarms and pendants, elevator phones, EFTPOS and ATM machines, teletypewriters and fax machines.
WHAT TO DO IF YOU HAVE A MEDICAL ALARM
* Call alarm provider and ask which internet or phone services over the NBN support your alarm and if any in-home wiring changes are required.
* Call your preferred provider and let them know you have a medical alarm and arrange any required wiring changes.
* Once the NBN has been installed and is working, confirm that your alarm is working correctly with your alarm provider.
