Mike,
Maybe you can answer a questions. I remember somewhere in NEC that the minimum wire gauge for initiating devices is 16AWG and notification 14AWG. Am I right. Can’t find it.

NEC 2008:
760.130
Wiring Methods and Materials on load side of Power Limited Fire Alarm Power Source:
760.130
Wiring Methods and Materials on load side of Power Limited Fire Alarm Power Source:
shall be permitted to be installed
using methods and materials in accordance with 760.130(A), 760.130(B)
or Both
(A) in accordance with 760.46 -solid or stranded Copper
(A) in accordance with 760.46 -solid or stranded Copper
760.130 (A) exception 2 allows them
to be installed as per 760.49 and 760.53
760.49(A) only Cu conductors 18AWG
and 16 AWG are permitted: PROVIDING they do not exceed the load
ampacities of 402.5
402.5 allowable ampacities are: 6A for
18AWG, 8A for 16AWG, 17A for 14AWG and 23 A for 12
AWG
AWG
and are in a raceway, approved
enclosure or listed cable/assembly.
760.53 adresses multiconductor
NON-power limited cables (ie those that can carry 120V A/C-like NYC
Fire Circuits)
760.130(B): as described in 760.179 (ie FPL,
FPLR, and FPLP)
760.179(A) solid or stranded Cu
760.179 (B) size in a multiconductor cable /assembly: no smaller than 26AWG; single conductor: no smaller than 18AWG
No where is there a minimum AWG for initiating /notification devices mentioned in NEC
760.179(A) solid or stranded Cu
760.179 (B) size in a multiconductor cable /assembly: no smaller than 26AWG; single conductor: no smaller than 18AWG
No where is there a minimum AWG for initiating /notification devices mentioned in NEC
Maybe in NYS Fire Code?
Checked that----nope!
