CSL Dualcom


CSL DualCom are the UK’s leading provider of dual signalling systems and have products installed in over 80,000 premises including thousands of retail, small business and domestic sites. CSL invented integrated dual signalling back in 1996 and lead the way in ensuring that intruder alarm systems have the best possible chance of getting a signal from the protected premises to the alarm receiving centre.

The award-winning DualCom GradeShift® range provides a single hardware intruder alarm signalling solution that is priced according to the grade your customer requires. It uses both the Vodafone network and your telephone and/or IP path to transmit intruder, fire and personal attack signals at high speed. Once the alarm is confirmed as genuine the Police are notified.  DualCom uses multiple signalling paths to ensure that DualCom will always have a back-up path in the event of an accidental or deliberate fault on any path.
