This code establishes the guidelines for the planning, design, selection, installation, and maintenance of automatic fire detection and alarm systems. It covers zoning rules, detector spacing, wiring requirements, and integration with other building safety systems to ensure reliable early warning during fire incidents.
Provides guidelines for the planning, design, installation, testing, and maintenance of automatic fire detection and alarm systems.
Quick Reference Values
maximum floor area per zone2000 sq.m
maximum search distance in zone30 m
minimum alarm sound level65 dB(A) or 5 dB(A) above ambient
minimum distance of detector from wall0.5 m
standby battery duration24 hours normal + 30 mins alarm
maximum travel distance to manual call point30 m
Practical Notes
Keep detectors at least 1 meter away from HVAC air supply grilles to avoid delayed response due to air dilution.
End-of-line (EOL) resistors must be installed at the last device on conventional circuits, not inside the panel, for proper circuit supervision.
The fire alarm control panel (FACP) should be placed in a constantly manned location, typically the ground floor reception or security control room.
