NICET Fire Alarm case studies
NICET Fire Alarm · Put your knowledge to work in context.
The NICET Fire Alarm Systems (FAS) certification is one of the Fire Protection/Building Systems programs offered by the National Institute for Certification in Engineering Technologies (NICET), a not-for-profit certification body headquartered in Alexandria, Virginia. It is intended for technicians, designers, installers, and inspectors who lay out, install, wire, program, inspect, test, and maintain fire alarm systems, and who want their documented work experience and code knowledge verified by an independent third party rather than by an employer alone. The NICET Fire Alarm case studies are 5 cases and about 3,860 words.
