Standard alarms rely on sirens or flashing lights to deter intruders, but if no one is around to act, the response can be delayed. With monitored intruder alarms, your system is observed by trained operators who are alerted immediately when the alarm activates. If activated, they will:
This fast and proactive response means your premises are protected day and night, even when unoccupied. For many, investing in a monitored intruder alarm is the difference between stopping a break-in quickly and paying for the damage later.

CSL Dualcom Intruder Alarm Monitoring
CSL’s market-leading signalling solution, Dualcom, uses Radio and LAN paths to signal alarms to an ARC. We use their Gradeshift Pro 2 Wireless 4G dual-path signalling at any grade, with unrivalled management tools.
CSL’s dual-path signalling solution utilises a combination of two radio paths, or one radio and one LAN path, to signal an alarm. Each SIM operates on an independent network from the other for total resilience.
We also install CSL connected devices from Orisec, Pyronix, Eaton, and other leading brands, to communicate to our ARC partners without additional hardware. CSL Connected still uses CSL’s gemini network for fully compliant signalling to the ARC.
Old Alarm Transmission System (ATS) Grades
Often our clients come to us with old specifications, or insurance requirements referencing the old grading. The below lists the old grading scheme, as well as the catastrophic failure reporting time. This can be compared to the above table to choose appropriate signalling.
Our expert team can review your existing setup, update your specifications, and ensure your intruder alarm monitoring meets current industry and insurance requirements for complete peace of mind.
