Can fire alarm wires be spliced?
Section 300.15(B) would permit the splice to be in an integral junction box or wiring compartment of approved equipment. Section 300.15(F) permits a fitting to be used in lieu of a box but not for a splice or termination in the fitting, so a box would be required for a splice in a power-limited fire alarm circuit.
