Depending on the specifications, usually, conduit is run with flex drops to the devices on the T-bar or in the walls, but as you can see, CEC allows a variety of methodsI'm looking to install a new strobe to an existing supervised FA system and I noticed that some of them are connected with conduit and some used BX. I was under the impression one cannot use anything else but conduit. What's your opinion guys?
