CSL invented integrated dual signalling back in 1996 and pioneered the move from wired to wireless technology in the electronic security industry. We offer installers a simple and reliable product - powered by the robust Gemini Platform. As the trusted market leader we are chosen to protect nearly half a million premises throughout Europe including many major retail brands.
The DualCom GradeShift Range, the UK’s fastest selling and most used dual signalling system, offers installers a reliable product that is easy to install on a single hardware platform for any grade of risk. It provides multiple signalling paths that embrace all available technologies.
Our single path options – DigiAir, G2r and G3r – eliminate call costs and are the ideal solution where there is no telephone line available.
All products are supplied with the multi-network WorldSIM which uses a patented roaming algorithm to increase signal reliability and reduce false alarms. The WorldSIM is guided by Gemini to automatically select the best network so that fewer line faults are sent to the Alarm Receiving Centre, meaning fewer false alarms for installers and end-users. Our point-to-point IP services eradicate the dependence on hard-wired IT infrastructure whilst our UDL options enable Remote Servicing & Diagnostics (RSD), quicker programming and extended signalling formats.
