NBN Alarm Systems, Installation & Service Melbourne

The National Broadband Network (nbn™)

The rollout of the nbn™ network will involve new technologies and many existing monitored alarm systems may not be compatible with these at all times.

It’s important to contact us before moving to the nbn™ network, to ensure your alarm monitoring service can continue without disruption. We will provide advice as to whether your existing monitored alarm can be directly connected to the nbn™ network, the limitations of doing this and recommend the best solution available to suit your individual needs.

Will my alarm system work properly when connected to the nbn™ network?

Unfortunately, there is no simple answer to this question as it depends on a variety of factors, including the nbn™ network technology being deployed in your area, the brand and model of your alarm system and the Retail Service Provider (RSP) you select.

Due to most existing systems being designed to transmit via traditional copper voice-based phone lines, if you elect to direct connect your alarm system to the nbn™ network you will require your RSP to provide an nbn™ service that includes a UNI-V (Voice) connection. A UNI-V connection is designed to support legacy equipment like alarm systems, fax machines, EFTPOS terminals, fire and lift alarms.

However UNI-V connections are not available in all nbn™ network areas due to the technology deployed and some RSP’s do not offer this type of connection. It is also important to understand the limitations of connecting your alarm to the nbn™ network as there is an increased potential for alarm signals not to be transmitted correctly and a possibility some older alarm systems may not be compatible with the nbn™ network at all.

Will my alarm system still be able to communicate during a power outage when connected to the nbn™ network?

Unlike traditional copper voice-based phone lines, the nbn™ network equipment that is installed in your premises relies on a local power supply to operate. Therefore if power is lost to your premises your nbn™ connected equipment and subsequently your alarm will not be able to communicate during the period of the power outage.

In some cases your RSP may be able to provide you with a local back-up battery for your nbn™ network equipment, however this will not provide the minimum 16 hours of battery back-up time required of an Australian Standard AS2201.1 monitored alarm system.

If you have a Fibre to the Node (FTTN), Fibre To The Building (FTTB) or Hybrid Fibre Coaxial (HFC) nbn™ network topology in your local area then the network itself is unlikely to provide 100% battery backup during a power outage.

What does Excell Security recommend?

To ensure your monitored alarm system continues to operate reliably and during power outages, we strongly recommend Permaconn.

What happens to my existing phone line after the nbn™ network becomes available?

When the nbn™ network is made available at your location, an 18 month transition period commences for you to select your nbn™ services from one of the many RSP’s operating in your region. At the end of the transition period, there is a regulatory obligation to disconnect the traditional copper voice-based phone line from your premises.

This means you will need to move your monitored alarm system during the 18-month transition period to enable it to continue to be monitored. We recommend you commence transitioning as soon as possible when you become aware the nbn™ network will be available in your area to eliminate any disruptions to your monitoring service.

I’m already connected to the National Broadband Network (nbn™) and my alarm system seems fine.

Some RSP’s may have advised you that your alarm system will be unaffected by this change and they will simply connect your alarm system to a UNI-V port on nbn™ network. You need to be aware your alarm may not operate correctly during a power outage and there is no guarantee that your alarm system will be able to reliably communicate using this method at all times.
