Direct answer
Wireless protection system is a defined term in the International Building Code (IBC) 2009, in Fire Protection Systems. The code's own words are: “A system or a part of a system that can transmit and receive signals without the aid of wire.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 4 chapters of this corpus, most often in Fire Protection Systems (IBC 2009), Fire Protection Systems (IFC 2009), Definitions (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.
