Cable size of Notification Appliance Circuit on fire alarm system

[paul2gh]

Hi everybody,

I plan to choose cable for speakers on NAC circuit. The length is 300m. Speakers are tapped at 1W rating. At most 12 speaker are connected on one NAC circuit. Please advise how to decide the size?

If the cables are placed in rigid metal conduits, can we install them along with the twisted pair cables for signal device circuits in the same conduits?

Is there any code or document related to this topics?

Thanks

I would check the websites of the alarm panel manufacturers for their recommendations.
