NICET In-Building Public Safety Communications (IB-PSC) Technician Level I Exam
Exam Coverage Summary (Point Form)
Based on NICET's IB-PSC content outline and job task analysis :
• Codes and Standards (15-20%) : NFPA 1225 (ERCES installation), NFPA 70 (NEC Articles 250, 810,
820), IFC (coverage requirements), NFPA 72 (fire alarm monitoring)
• Radio Frequency (RF) Theory (10-15%) : Signal propagation, frequency bands (700/800 MHz),
decibels (dB/dBm), gain, loss, isolation, oscillation
• System Components (15-20%) : BDAs (Bi-Directional Amplifiers), donor antennas, distribution
antennas, coax cables, hybrid/fiber optic cables, passive components
• Installation Practices (15-20%) : Equipment mounting, cable routing and support, grounding and
bonding (NEC Article 250), connector termination
• Coverage Requirements (10-15%) : 95% general areas, 99% critical areas (IFC/NFPA 1225),
delivered audio quality (DAQ)
• Testing and Commissioning (10-15%) : Signal strength measurements, spectrum analysis, PIM
testing, battery backup verification, fire alarm interface testing
• Safety (5-10%) : RF exposure hazards, electrical safety (lockout/tagout), ladder safety, PPE
requirements
• Documentation (5-10%) : As-built drawings, test records, maintenance logs, permit
requirements
Section 1: Codes and Standards (Questions 1-40)
