GradeShift Pro 2

Part of the DualCom Pro Range, 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. GradeShift Pro 2 is also compatible with CSL Live and the My Base App. 
GradeShift Pro 2 Radio/Radio uses two active 4G WorldSIMs, each with its own radio module, one as the primary and one as the secondary path. A third standby SIM acts as a backup to the primary SIM on the primary path. GradeShift Pro 2 LAN/Radio uses LAN connectivity for its primary path and a 4G WorldSIM as its secondary path. A standby WorldSIM is also supplied.

DigiAir Pro 3

CSL’s single-path signalling solution, also part of the DualCom Pro Range, utilises a 4G Radio path or a LAN path to signal an alarm. The Radio variant also comes with a standby SIM as a backup to safeguard your system. Both SIMs operate on an independent network from the other for total resilience. DigiAir Pro 3 is also compatible with CSL Live and the My Base App.

MiniAir 2

The ideal mobile upgrade for Digital Communicators, MiniAir 2 is a single-path signalling solution that utilises a 4G/LTE-M path to signal an alarm from a protected premises to an ARC. It comes with a standby SIM as a backup to safeguard your system, if the active SIM fails. Both SIMs operate on an independent network from the other for total resilience. ​It is designed for both residential and commercial premises as an affordable upgrade from a digital communicator to secure signalling.

Communications Providers are currently in the process of upgrading their customers from the existing analogue PSTN network to new IP-based services.This means PSTN-based alarms will fail and need to be upgraded. MiniAir 2 provides a cost-effective, future-proofed, radio signalling solution to ensure alarm systems can still send signals to the ARC. This professional signalling upgrade also ensures systems maintain their existing Police URNs.

CSL Router

This IoT Router sends data via a 4G SIM, providing an encrypted connection to the internet on sites where wired broadband is unavailable, impractical or slow. The 4G backup option upgrades an existing broadband service to a private network, providing a reliable failover business solution if your wired broadband goes down.

Single and Managed Multi-Path options are available depending on the installation, utilising a combination of 4G, IP, xDSL and FTTC connectivity. For installations that require professional monitoring, CSL Router can be connected to an Alarm Receiving Centre. It is also available as a self-monitoring solution with the ability to upgrade to a full ARC Connection at any time. All variants arrive pre-configured for quick installation and are supplied with the appropriate monthly data SIM bundle to help manage costs.


​Our multi-network IoT SIMs are available with flexible tariffs to provide you with the best option to control costs. The flexible data bundles vary from 1MB to 500GB and beyond. If the requirement of an application changes after installation the tariff can be easily adjusted. To protect your chosen device, every SIM utilises a Private APN and our global roaming capabilities ensure the best guarantee of network availability. CSL SIMs can roam on to 4G on all major networks, as well as being able to send data via 3G and 2G, offering even greater resilience. The SIM’s static IP address allows end-users to connect to their device on-demand, in real-time, for requirements such as remote viewing.
