Codes, fire alarm and intrusion awareness, and firestopping
Awareness for low-voltage technicians: how the NEC (a US example) and the authority having jurisdiction shape cable choices and installation, where fire alarm and intrusion alarm work needs a licence and must be left alone, and why every penetration of a rated wall or floor needs a listed firestop system.
