NEC Requirements

Power-Limited

Installation Requirements

Article 760 permits wiring methods for fire alarm systems that are less stringent than installations for normal light and power service. This is true for power-limited circuits. In general, power-limited circuits may use the installation methods in NEC Chapter 3 All the fire alarm circuit conductors may be installed in conduit or raceway the same as any other power circuit in a building. While this method is permitted, it can be expensive. That is why there are alternative installation methods for power-limited fire alarm circuits., the circuits may be installed using listed non-power-limited cables, or the circuits may be installed using listed power-limited cable.
