Analogue to Digital Switchover - What it means for your Alarm System?

Is your alarm connected to a traditional phone socket? Have you moved to fibre?

If you are thinking of upgrading to full-fibre broadband with BT or Sky and you have an alarm system that uses a traditional phone line to send alarm notifications, then you may need to have this part of your alarm system converted to work off your broadband router. When you have full fibre broadband installed your old analog phone line will be disconnected and replaced with a digital phone line, and this could affect your alarm system.

The good news is, there is a solution! – CTB Alarms have already carried out hundreds of conversions to keep alarm notifications working with the new digital phone lines.

CTB Alarms are here to help keep your alarm system operating following the installation or upgrade to full-fibre, even if we didn’t originally install your intruder alarm.

What is the Digital Telephone Switchover?

BT has announced that work has begun to convert all analogue telephone lines and upgrade them to the new ‘Digital Voice’ service. Digital Voice is the name BT has given to its new home phone service which delivers your calls through your Smart Hub. This new digital phone service uses Voice over Internet Protocol (VoIP), the same type of technology used by services such as FaceTime, Skype and Zoom. Put simply, VOIP are calls made over the internet. So, essentially these digital lines will use the internet to carry telephone calls and the analogue telephone lines will become obsolete.

Why are telephone lines changing?

The need to switch to broadband has arisen because some parts of the existing telephone system are old and rely on physical components like copper wires to carry calls. Also, demand has risen which has put the old system under pressure. VOIP calls are not a new technology, they have been in use for some time with Applications such as Whatsapp, Facebook, and Skype. You may hear terms such as ‘analogue’ or ‘PSTN’ in connection with the switchover. PSTN stands for Public Switched Telephone Network and both analogue and PSTN relate to the system which will become obsolete once the switchover to digital is complete.

When will the digital telephone switchover happen?

The rollout of the digital telephone switch over or ‘Digital Voice’ has already begun and it is expected that by 2025 all telephone lines will have been converted to fibre.

What does this mean for your home security system?

Many security alarm systems use the Public Switched Telephone Network (PSTN), your analogue phone line for alarm signalling. The alarm is plugged into the analogue telephone line and when an intruder is identified the alarm is raised via this phone line. So, once the switchover to digital happens, these devices will no longer work.

What do I need to do to get my alarm ready for the digital switchover?

The changes needed will depend on your individual circumstances, the type of alarm and any other factors around the alarm installation. In most cases, a simple upgrade to your alarm system, for example replacing an analogue signalling device with a digital one, will make it digitally compatible.

CTB Alarms are working with customers, old and new, to help them prepare for the switchover from analogue to digital and keep their alarms operating and their property protected.

CTB will send an experienced member of our alarm engineering team out to your property to take a look at your alarm system. They will carry out a short survey to enable them to tell you what needs to be done to ensure your alarm continues to work the roll-out of the digital switchover. You will be provided with a clear, fair and competitive price for any required upgrades, and in almost all cases we will be able to make the changes to your alarm during the same visit.
