Removal of Current Copper Network Affecting PSTN Communications Devices.

We have recently received an update from BT regarding the removal of current copper networks on an exchange basis for new IP solutions. These changes are due to start on a phased implementation from September 2020, and the latest estimates conclude this will be an ongoing project until the end of 2025.

The British Security Industry Association (BSIA) have issued a formal press release on this matter which can be read at www.bsia.co.uk/blogs/98/bsia-urges-alarm-installers-to-take-acti. In addition to this, the BSIA have issued a brochure outlining the changes, its importance, and the impact it will have on our industry which can be viewed on our website at www.pyronix.com/uk/documents/bsia-form-349/.

When a premises communication lines are upgraded, it has the potential to cause problems on PSTN communication modems installed in control panels. These were designed to operate on the current copper cabled grids. We cannot guarantee their current operations on the new digital networks and subsequently cannot be held responsible for any issues encountered.

Given alarm systems are often used for Police calling and/or insurance policy conditions, it is imperative that installers assess their estate of installed security systems to ensure that they will continue in working order.

We would strongly recommend against utilising PSTN modems as a communication or signalling solution on all future installations.

We also recommend where possible, upgrading current security systems in the field to IP based communications such as our Wi-Fi, LAN and GPRS solutions. If you are unsure whether an existing system has the capability for IP based communication, please review our document here www.pyronix.com/uk/documents/control-panel-communication-options/, which can help you identify compatibility.
