I roughed a house for hard wired smokes useing 14-3 romex. Now the alarm guy has sold the owner on useing his smoke detectors on his fire alarm panel.
Can he use my 14-3 romex for interconnection of his detectors?
I thought he must use fire alarm cable, but he says he can use 2 of the conductors out of the 14-3 for his system...
shortcircuit
