Power Supply with Battery Backup FAQ’s
From October 2nd 2014 all NBN Fibre services will have the option of choosing to have the Power Supply with Battery Backup installed or not. This battery backup, when fully charged, can allow a phone (which does not require mains power to operate) plugged into a Uni-V port on your Fibre NBN Connection Box to work for between 3 and 11 hours (Approximate usage is 5 hours) in the event of a power outage.
If you choose to have the NBN Power Supply Unit with Optional Battery Backup Service (pictured below) as part of your installation, it comes with the battery when it is first installed into a home or business.
In the event of a power outage, your landline phone and internet services over the NBN won’t work if the battery is faulty or missing.
Boom Broadband highly recommends that the Power Supply Unit with Optional Battery Backup be installed for ALL new connections. Boom Broadband also highly recommends that users have an alternative means of communication, such as a mobile phone, available in the advent of a power outage.

Do I have to have the Power Supply with Battery Backup installed?

No. You do not have to have the power supply with battery backup installed, but it is the recommendation of Boom Broadband that all users who wish to utilise Uni-V phone service to have the battery backup installed.
Boom Broadband also recommends that an alternative means of communication, ie: mobile phone be available to users in the advent of a power outage.

Why would I choose NOT to have the PSU with Battery Backup installed?

The PSU with Battery Backup, pictured below is wall mounted and can take up considerable space.

Customers who choose to have the PSU with battery backup installed will also be responsible for the ongoing maintenance of the Battery Backup, including replacement of the battery when it has expired.

Will the Power Supply Unit with Battery Backup power my phone during a power blackout?

Only standard corded phones (that don’t need to be plugged into a power point) will work during a power outage, and only if your phone service is also provided over the NBN connection box’s voice (UNI-V) port. All other devices require their own battery backup to operate during a power outage.
If your phone plugs into a separate router/gateway from your phone or internet service provider, you won’t be able to make calls unless that router/gateway also has its own battery backup.

Will I be able to access the internet in the case of a power outage?

No. The Power Supply Unit with Battery Backup will provide power to the NBN Connection box Uni-V voice ports ONLY.

It is always good to have another way of calling someone during a power outage in the case of emergency such as a charged mobile phone. To ensure that your phone (or data) services continue to operate during a power outage please note:

Examples of devices that require their own battery backup include wireless routers, all mains powered phones, computers or modem/routers. Uninterruptable Power Supply (UPS) systems help power devices during a power outage and are readily available through technology retailers.

Boom Broadband does not provide phone handsets and you will need to check with the manufacturer of your handset if the device can operate during a power outage.

Will the battery backup unit power my medical and/or security alarms?

No. Medical and security alarms that operate with your NBN Uni-V phone service will require a separate battery backup unit to continue operating during a blackout.
It is the responsibility of the end user to ensure that any medical or security alarm equipment will operate in the advent of a power outage and that this equipment is compatible with the NBN Uni-V phone service. Please contact your alarm supplier for further details should you have any concerns.

Do not dispose of them in your household garbage or recycling.
Batteries that end up in landfill contaminate the soil and can leach acid, lead and other pollutants into ground water.
Some battery retailers and local councils (Click Here) accept used batteries for recycling.

How long will the battery backup last?

If you have a Power Supply with Battery Backup, your NBN connection box will continue to be powered for approximately five hours during a power outage.

• When approximately 40% of the battery charge is remaining (after about 3 to 3.5 hours), the power supply will automatically turn off to preserve the remaining charge for emergency use.
• When you need to use the remaining charge press the emergency reserve button and within a few minutes your services will operate for the remaining 1.5 to 2 hours.
• Extremely cold conditions (less than -1 degrees Celsius) may cause the battery to run out more quickly.

How can I make sure the backup battery keeps topped up?

To ensure the backup battery works when you need it, please maintain it by following the advice given in the NBN Co. NBN Fibre User Guide.

• Regularly check the battery indicators lights and pay attention to audible alarms, (see page 21 for a guide to indicator lights and alarms) as these may indicate a problem with your battery.
• When your battery is used as indicated in the NBN User Guide, it will age to about 70% of its original capacity in around three to five years.
• A battery can age sooner if not kept at room temperature (around 20 degrees). Warmer temperatures can accelerate aging of the battery.
• Turning the power on and off frequently will cause the battery to age earlier and reach 70% of its capacity in around one to two years.
• Please ensure the battery is replaced when needed.
