Non Power Limited FA circuits/devices

[tschooley]

I am looking for examples of Non Power Limited Fire Alarm circuits/devices that meet the requirements of NEC 760.

I have a presentation on the 17th of December. Can anyone offer any insight?

Thanks,

Troy Schooley

They would be a line voltage fire alarm with 120v bells and devices. they are probably few and far betwee.

From what I understand, many FACP power supplies can be purchased either 24V power limited or 24V non-power limited. Depends on the application.

fyretek,
Regarding your link to the CI cable, have you had much call for it? Generally it has very limited use, and many argue that there is no code requirement for it.

BTW, I specify its use on many of my larger buildings I design.
