Intelligible Voice Evacuation
STI-CIS Analyzer: A Portable Tool to Test Voice Intelligibility and Audibility
|
Emergency voice evacuation systems play an important role in the orderly evacuation of buildings during emergencies.
NFPA 72, the National Fire Alarm Code, requires that voice alarm systems be intelligible. This requirement ensures that vital emergency messages transmitted through a building's voice evacuation system can be clearly heard and understood.
The STI-CIS Analyzer, a technological breakthrough, enables you to objectively validate that your building's emergency voice evacuation system is fully code compliant.
