As a systems integration engineer with long years of Gulf & central Asia experience, I have reviewed hundreds of fire detection installations projects.
Here are the top 10 NCRs I see raised again and again on fire detection projects in the Gulf:
1. Wrong cable size installed The drawing specifies 2.5mm² but site installs 1.5mm². Always verify cable size before pulling.
2. Detector installed in wrong zone Addressing errors during programming cause detectors to report to the wrong zone on the FACP.
3. Missing end of line resistor Without the EOL resistor the loop shows an open circuit fault on the panel.
4. FACP not connected to BMS Integration requirement is missed during installation — caught only at commissioning stage.
5. No commissioning certificate from manufacturer System is signed off without OEM witness or manufacturer commissioning certificate.
6. Detector spacing exceeds NFPA 72 maximum Smoke detector coverage exceeds 7.5m x 7.5m. Drawing not checked against standard.
7. Cable not fire rated Standard cable installed instead of FP200 or equivalent fire rated cable.
8. Manual call point at wrong height MCP installed at incorrect height — NFPA 72 requires 1.4m from finished floor level.
9. No cause and effect matrix testing Sounders, outputs and suppression interlocks never verified against the cause and effect document.
10. As-built drawings not updated Final installation differs from approved IFC drawing — as-builts never updated before handover.
