Alarm signalling change The ‘Next Generation’ of alarm signalling is replacing the analogue signalling service in the UK. As a Guardian Alarms customer, your alarm system will be upgraded during an inspection visit. We’ll provide the full installation and support service for your alarm signalling upgrade.

We'll always be there, even when you're not.
