Our Intruder Alarm Systems Solutions
Wired Alarm Systems
Hardwired systems offer the most reliable and tamper-resistant protection. Ideal for new builds and properties undergoing renovation.
Wireless Alarm Systems
Fully wireless systems with no cable runs required — perfect for listed buildings, tenanted properties, and minimal-disruption installs.
Smart Alarm Systems
App-controlled systems that let you arm, disarm, and monitor your property remotely from your smartphone, anywhere in the world.
Monitored Alarms
Linked to a 24/7 Alarm Receiving Centre (ARC). If your alarm activates, trained operators respond immediately and contact the police if required.
Grade 2 & Grade 3 Systems
Fully compliant commercial-grade systems meeting PD6662 and EN50131 standards — required by many insurers for commercial and high-value properties.
Maintenance & Servicing
Annual and bi-annual service contracts to keep your system operating at peak performance and maintain your insurance compliance.
