Occupant Notification Overview:
* General requirements for notification appliances (listing, physical construction, mechanical protection, mounting, connection)
* Audible signaling V general requirements (high ambient noise area, maximum total sound pressure 110 dBA, intelligibility for voice systems, minimum sound level for alert and evacuation tones)
* Public mode audibility requirements (public mode includes signaling to general occupants for them to take action on their own to evacuate or relocate etc.) o 15 dB above average ambient sound levels or 5 dB above maximum ambient sound level (which ever is greater) o Allowances for reduction of audibility under certain conditions
* Private mode audibility requirements (private mode includes signaling to facility staff or emergency personnel to take action) o 10 dB above average ambient sound levels or 5 dB above maximum ambient sound level (which ever is greater) o Allowances for reduction of audibility under certain conditions
* Sleeping area audibility requirementsLocation (mounting height) requirements for audible appliances o 15 dB above average ambient sound levels, or 5 dB above maximum ambient sound level or 75dBA (which ever is greater)
* Visible signaling requirements V general requirements (light color, flash rate, flash duration, listing to UL 1971)
* Location (mounting height) requirements for visible appliances
* Spacing for visible appliances in rooms (indirect signaling V a minimum intensity of reflected light)
* Spacing for visible appliances in corridors (direct signaling V occupants view strobes directly)
* Synchronization for visible appliances (more than two appliances in same room or field of view must be synchronized to reduce potential risk of seizure to people with photosensitive epilepsy)
* Requirements for emergency voice / alarm communication systems (performance and operation)
