Do Fire Alarm Circuits Need To Be Segregated From All Other Circuits


Recommended Posts

Certainly the Fike manual tells you to keep fire cables at least 20cm (IIRC) from any other electrical cable - and if you wanted to rely on BS7671, that also compels you to follow manufacturers instructions, so...

 

As above, @Scotmod hasn't signed in for about 3 years, so better to start a new thread. And, welcome :)

Inductance is measured over a conductors parallel length, this is why you may cross cables perpendicularly but they must have separation/segregation when parallel.
