The companies below represent over 80% of the UK Insurance market.

“Allianz have reviewed recent developments in Intruder Alarm Dual Path signalling & are pleased to confirm that CSL DualCom GPRS G3 with Priority Polling can be specified for medium risks. CSL DualCom GPRS G4 should be specified for higher risks. Both GPRS G3 & G4 operate within CSL’s Gemini Managed Network incorporating Gemini Callback.” 

Andrew Miller Manager Risk Control – Allianz Commercial


“Following a review of available systems AXA are pleased to confirm that DualCom GPRS G3 with Priority Polling is acceptable for small/medium risks and DualCom GPRS G4 is acceptable for higher risks. DualCom Plus can also continue to be specified for medium/high risks.” 

Douglas Barnett Head of Customer Risk Management – AXA Insurance


“The development of CSL’s Gemini Managed Network means that Norwich Union are happy to accept DualCom GPRS G4 signalling as one of our preferred signaling solutions for remotely monitored Intruder & Hold Up Alarm Systems installed at commercial & domestic premises. Similarly, the development of ‘priority polling’ means we are happy to accept the use of DualCom GPRS G3 at some lower risk commercial, and many domestic, premises.” 

Allister Smith Property Risk Manager – Norwich Union


“RSA’s preferred products from the current CSL signalling range are the new GPRS G4 and the existing DualCom Plus. These are considered to be acceptable alarm signaling systems for the vast majority of UK theft risks. CSL’s GPRS G3 product will be acceptable for those risks that we class as low to moderate.”

Steve Clark Technical Manager Risk Control – Royal & Sun Alliance

Who are CSL Dualcom?

The CSL DualCom Group encompasses CSL DualCom Security and CSL DualCom Health operating in the United Kingdom, Ireland and Sweden.

In 2006 the company was subject to a successful MBO led by Group CEO, Phil Hollett and Simon Banks, founder and Group Managing Director. Since the MBO, CSL has firmly established the DualCom brand as the UK’s best selling dual signalling system and the preferred choice for hundreds of thousands of professional installations in commercial, retail and high value residential premises.

The DualCom Gemini® Managed Network was introduced in 2007, which has since proven to be the most resilient and reliable managed network in the industry. Today, Gemini® handles over 1 billion calls each month and is the platform that provides the critical connectivity for over 200,000 protected premises throughout Europe.

CSL DualCom is an ISO9000 certified company and the only signalling service provider to have invested in a purpose built and fully resourced Network Operations Centre.

CSL Dualcom Security

CSL DualCom invented integrated dual signalling back in 1996 and pioneered the move from wired to wireless technology in the electronic security industry. DualCom is now trusted to protect over 200,000 premises throughout Europe including many major retail brands.

The DualCom GradeShift® Range, the UK’s fastest selling 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. The introduction of the WorldSIM® to the DualCom GradeShift® Range boosted this popularity and reduced false alarms by almost 90%. 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.
