Hi guys,
I have a FA annuciator that is being added to the current scope of work. I recieved the Simplex-Grinnel LCD unit and it says the back box must be hooked to a "dedicated earth ground per article 250" It also says this is to arrest transients or something along those lines. There is no line power in the unit. Does anyone know what code they are referring to? I'm not to sure what they mean by "earth ground", but I was planning on just taking a wire up to the building steel.
Thanks in advance
