Re: using CAT5 for smoke detectors



> Can't do it. NFPA72 says 18 gauge fire rated wire.

An installer on another forum says he uses CAT5 for smoke detectors.  To
avoid nicks in the 24AWG and potential breakage, he strips the wire with his
fingernails.  Says he's been doing it for years.  I had assumed CAT5 was not
to code, hence my question.

Best,
