NACOSS GOLD (Security Systems)

The NACOSS Gold is the (NSI) National Security Inspectorates leading standard for the Security Industry, covering the design installation and maintenance of all security systems including CCTV, access control and intruder alarms. This level holds the greatest perceived value in the security industry by the police, fire and rescue services and insurance companies. NSI approval is only given to those companies that can consistently meet NSI's exacting standards. Both above technical accreditations are also subject to compliance with an effective quality management system complying with BS EN ISO 9001. Tri Management operate a Management System and hold other relevant accreditations, so our clients can be assured that we are independently audited regularly to ensure continual improvement and delivery to the highest standards.
