Hello,
I'm preparing a design to replace an existing fire alarm system with voice evacuation in a six-story building in Southern California. I'm not familiar with the special requirements for high rise buildings. The existing wiring is run in EMT throughout, my question is: is the conduit required or can we run the wiring for the replacement system "open".
We are designing this system as a "like-for-like" replacement to avoid a full submittal to the city.
Thank you,
Nathan
