What is intruder alarm signalling?
Intruder alarm signalling refers to the process of transmitting alerts from your alarm system to a recipient, such as an Alarm Receiving Centre (ARC) or your mobile. When an alarm is triggered by an intruder, the system will immediately send a signal. In the UK, modern signalling solutions increasingly use secure methods such as cellular networks or an internet connection.

The closure of the PSTN lines in the UK
The UK is currently phasing out the Public Switched Telephone Network (PSTN), with a complete switch-off planned by January 2027. This means that traditional landline alarm signalling will soon be obsolete. If your alarm system still relies on PSTN, now is the time to upgrade to a more future-proof solution. Switching to digital signalling such as cellular (GSM/4G) or IP (internet-based) ensures your alarm system remains operational and compliant as the UK moves to an all-digital communications network.
Are you ready for the switch-off?Types of intruder alarm signalling
Cellular (GSM/4G/5G)
Uses mobile networks for fast, wireless communication, unaffected by landline changes.
IP/Broadband
Utilises your internet connection to send alarm signals, ideal for properties with reliable broadband.
Dual-Path
Combines two technologies (e.g., cellular and IP) for maximum reliability, ensuring there’s a backup if one path fails. Dual-path solutions are now the gold standard for UK security systems, providing resilience against network outages.
Reliable signalling matters
Fast, dependable alarm signalling is paramount for security and peace of mind. Immediate alerts mean that any unauthorised access to premises is dealt with quickly, minimising risk. Reliable signalling is also required for compliance with UK insurance and industry standards.
Compliance and certification
Our intruder alarm signalling solutions are third party certified and fully compliant with UK and European standards, including EN 50136. Upgrading from the PSTN ensures your system meets current insurance and regulatory requirements.
