BORN IN 2009, QDOS was created by people with key experience from the fire alarm and fire safety industry. This experience sets us apart from mainstream CAD outsourcing companies; our passion and knowledge on fire safety has led us to set the standard for Fire Alarm Zone Plans, become BAFE and NSI Silver accredited and FIA members. Our team is kept updated with the latest technology and industry standards, consistently producing professional and compliant drawings for our clients.
