Direct answer

Visible alarm notification appliance is a defined term in the International Building Code (IBC) 2009, in Fire Protection Systems. The code's own words are: “A notification appliance that alerts by the sense of sight.” 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.

These two are the closest pair in the 2009 I-Codes: about 82 per cent of their defining words are the same. The code states both and compares neither, so the difference is worth naming.

Audible Alarm Notification Appliance (IBC 2009)hearing

Everything else in the two definitions is shared. If a project turns on which of the two applies, those words are the whole of the test — and a local amendment that edits one of them without editing the other moves the boundary between visible alarm notification appliance and audible alarm notification appliance.

Frequently asked questions

What is the code definition of visible alarm notification appliance?
