Cl 402
Fire alarm cable and circuit requirements
The fire alarm cabling tool reads one row per circuit type. Each row holds the smallest conductor size for two cores and for more than two, and the stranding threshold. It also holds the insulation resistance criterion, the AS/NZS 3013 fire rating and integrity time, and the supply subcircuit label. A null size means Clause 402.1 sets none for that circuit.
