Diamond was founded in 1987 by Tom Snoddon, a Belfast born and bred entrepreneur who saw a niche in the market for a local company with the capabilities to deliver complex fire and security projects, to a highly professional standard. The company’s original maxim was “Large enough to cope, small enough to care”. This personal level of service has been ever present throughout over 30 years in business, and our customers feel supported and protected. Diamond is a leading provider of high quality commercial security and life safety systems, including Fire Detection and Alarm Systems, CCTV, and Intruder Alarm Systems.
