Direct answer
Manual fire alarm box is a defined term in the International Building Code (IBC) 2009, in Fire Protection Systems. The code's own words are: “A manually operated device used to initiate an alarm signal.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 8 chapters of this corpus, most often in Fire Protection Systems (IBC 2009), Fire Protection Systems (IFC 2009), Construction Requirements for Existing Buildings (IFC 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.
