Is Your Home Alarm System Ready for the Digital Phone Line Switch?

Why this topic matters & Core context

PSTN (Public Switched Telephone Network) disconnection is currently underway across the UK, rendering traditional alarm communicators obsolete. Many homeowners remain unaware that their security system’s ability to 'call out' during a burglary relies on these legacy copper lines.

As an installer, I strongly recommend auditing your alarm's communication path immediately. If your system is hardwired to a phone socket, you must transition to a digital signalling device, such as a 4G-enabled communicator or a dedicated IP module that connects directly to your fibre router.

Identifying your system's technology

Alarm signalling equipment varies significantly in how it transmits data to the alarm receiving centre (ARC). You need to identify whether your panel uses a basic voice-dialler, an older Redcare unit, or a modern dual-path communicator.

Modern installations should follow current EN standards for alarm transmission, which prioritize encryption and multi-path connectivity. We often replace legacy boards with updated control panels that support mobile app connectivity, ensuring you get instant notifications even if the physical line is severed.

Best practice & insurance compliance

Dual-path monitoring is the gold standard for insurance compliance in the modern digital landscape. By combining a fixed IP internet connection with a 4G/5G cellular backup, you create a failsafe that prevents a single network outage from leaving your home vulnerable.

Review your home insurance policy documents to ensure your current alarm status meets their 'active' requirement. Many insurers now mandate that systems remain monitored, and failing to update your hardware could void your cover in the event of a successful burglary.
