What is an Alarm Signalling Device?

Our simple and reliable alarm signalling products offer a professional and trusted solution for every grade of risk. They enable the safe delivery of alarms and data from protected premises to a network of leading Alarm Receiving Centres (ARCs). We manage millions of signals monthly, and our devices ensure critical alerts reach the right people, connecting seamlessly to emergency services and keeping businesses safe and secure.

Our solutions also include tools to monitor signal strength, ensuring that devices are polling correctly and that test alarms reach the ARC as expected. Additionally, features like QR code scanning for device registration enable instant commissioning, streamlining your setup and simplifying your installations for faster deployment.
