power-limited v nonpower-limited

[buck]

Very confused-- can someone tell me the differences between power-limited and nonpower-limited circuits for fire alarm panels.
Question posed to me was---"can I install 120v power in the same conduit,enclosures,etc as fire alarm wiring?" Thanks in advance

760.2 for definitions, then 760.26 or 760.55.

Most fire alarm system power supplies are listed as power limited, but some are not. Check the power supply (says it on the supply itself) and manufacturers wiring requirements.
