CSL DualCom was formed in 1996 when an opportunity to break a near monopoly in secure signalling was realised. CSL pioneered Dual Signalling, launching the award winning DualCom product in the November of the same year. It seems obvious now, but in the mid-nineties Dual Signalling was not on anybody’s agenda. In fact CSL had to lobby the standards creation bodies and opinion leaders of the time including Insurance Companies and the Police for a more effective means of transmitting Alarm Data. DualCom was the first product to confirm a line cut and subsequent alarms following a line cut. It wasn’t until the turn of the millennium before CSL’s competition caught on and launched other Dual Signalling on the back of the Industries’ acceptance of this now widely established technology. In 2000 CSL DualCom became a Vodafone Service Provider and a business partner of the world’s largest Mobile Telecoms provider. In 2006 a MBO was successfully led by the Operations Director, Phil Hollett and co-founder and Commercial Director, Simon Banks. CSL also raised additional funds to enable the DualCom GPRS product and the Vodafone/CSL Gemini Secure Signalling Network to reach its full potential. With the support of the UK’s Alarm Receiving Centres and Alarm Installers, DualCom has been installed in over 80,000 premises and has been adopted by thousands of Retailers, SMEs and Domestic customers as their Signalling of choice.

CSL DualCom continues to innovate with products such as the DualCom GradeShift® Range and DigiPlus®. The DualCom GradeShift® range is the fastest selling Dual Signalling product and is now the UK Market leader in net monthly sales, setting the standard for cost-effective secure signalling. CSL DualCom will continue to provide Alarm Installers with credible, trustworthy secure signalling at affordable costs whilst meeting the needs of the Insurance Industry and the stringent European standards.
