Most likely yes, as Tom points out, as long as the FA system is power-limited. The vast majority of fire alarm systems installed are power limited. The only non-power limited portions MIGHT be some of the speaker zones. Detection and control will be power limited.Wondering if anyone knows the code for this situation
I have an existing fire alarm running though my nurse call box. Is this allowed?
if not, does anyone know where i can find this in the code book?
Thank you, I forgot to mention that this is a hospital. Does that make a difference?Nurse call is typically an Art 725 class 3 circuit.
725.136 discusses separation from various other systems, including non power limited fire alarm.
I think your answer is in 725.139 (E) Class 3 cables with other circuit cables, including power limited fire alarm.
