Through a combination of commitment to customer care and the provision of experienced engineers and support staff Cannon has become one of the South West's leading fire & security design, installation & maintenance providers. Our systems have the ability to link to our 24hr manned Alarm Receiving Centre (ARC). You can either have a keyholder only response or full police response dependant on your requirements. Connection is achieved using any telephone line, with the option of added security using RedCare or Dualcom GPRS with its additional link using the mobile phone network as back up.
