National Security Systems Group


NSS took advantage of CSL’s ‘Better your Base’ programme to future proof their base. This programme involves CSL reviewing an Installer’s existing signalling base and suggesting a swap-out plan to suit the business. NSS were keen to take up the opportunity as they were looking to move away from the alternative signalling provider they were using at the time.


NSS work with a variety of sites that have different requirements including hundreds of ‘Subway’ stores. NSS chose DualCom DigiAir as their upgrade from PSTN. DigiAir utilises all mobile networks via WorldSIM instead of a telephone line to signal an alarm from the protected premises to the Alarm Receiving Centre (ARC). It is designed for low to medium risk premises and is an ideal upgrade for wired digital communicators as it eliminates call costs and phone charges. The connection to the DigiAir is also protected by the Gemini Platform, a Critical Connectivity platform responsible for the integrity of close to 1 million premises throughout Europe.


NSS experienced a smooth rollout process across their signalling base. To support NSS in their DigiAir rollout, CSL provided additional services as standard including: training from CSL Field Engineers, access to CSL’s Technical Support out of hour’s number for responsive customer service and logins were provided to CSL’s handy web portal Gemini Insight to manage their signalling estate. CSL’s Regional Sales Representative was also on hand to provide continuous support throughout.


By upgrading to DigiAir, NSS future proofed their signalling estate. A strong partnership has been established and NSS are looking forward to continuing to work closely with CSL and remaining at the forefront of the latest technologies and services.
