HKC Security supports installers through PSTN shutdown

Posted to Products on Tuesday, February 17, 2026 Share:

AS THE UK moves closer towards the shutdown of analogue PSTN telephone lines, security installers are being urged to act now to protect monitored alarm systems that still rely on legacy signalling. With this in mind, HKC Security is advising installers to future-proof their customers’ estates with reliable, British Standard-compliant dual-path communication solutions designed for fast retrofit and minimal disruption.

Ian Moore, head of technical for HKC Security, explained: “The retirement of PSTN infrastructure will directly impact monitored intruder alarm systems that depend on analogue lines to communicate with Alarm Receiving Centres (ARCs). Without an upgrade, these systems risk losing connectivity altogether, leaving end users without monitoring or emergency response and potentially invalidating insurance cover that requires compliant alarm signalling.”

Industry guidance recommends replacing analogue signalling with at least DP3-level dual-path connectivity. HKC’s range of IP and mobile-based solutions has been developed to support installers through this transition, delivering robust and insurer-approved signalling without unnecessary complexity.

Fast retrofitting

A suggested PSTN replacement is the HKC 4G Wi-Fi Dual Path Communicator, designed for fast retrofitting to Quantum70 and SW10270 panels. The plug-on module provides dual-path connectivity via 4G (with 2G fallback) and Wi-Fi, securely linking systems to the HKC SecureComm Cloud.

Key features include instant IP signalling to major ARCs, remote programming and maintenance, software updates, heartbeat monitoring and jam detection, as well as support for off-board antennas in challenging signal environments. End users also benefit from a modern experience via the SecureComm2 app, offering alerts, event logs and remote system control.

Continuity and compliance

For installers, the focus is on continuity, compliance and ease of migration. HKC solutions are designed to integrate seamlessly with existing systems, reduce time on site and provide confidence that upgraded installations meet insurers’ expectations for dual-path, British Standard-aligned signalling.

Ian Moore continued: “With the move to an all-IP network well underway, we are encouraging installers to engage customers early and plan upgrades proactively. By moving away from analogue dependencies now, installers can avoid future shutdown risks, while also delivering reliable and resilient security systems that will remain operational long after the PSTN switch-off.”

In conclusion, Moore informed Security Matters: “HKC continues to put installers first, offering technology that’s easy to configure, remotely managed and built to support long-term compliance while connectivity is changing.”
