AbstractThe 1995 National Building Code of Canada requires that fire alarm signals sound the Temporal-Three (T-3) pattern, as defined by the ISO 8201 i2Acoustics ? Audible Emergency Evacuation Signalli. This sound pattern has also been required by NFPA 72 since July 1996. It is intended that the T-3 pattern will become the standardized alarm signal heard around the world that will unequivocally mean ieevacuate the building immediatelyly. Although new and refurbished buildings have, for the past 5 years, been equipped with this new signal, no formal public education has taken place to inform building users about the meaning and response expected from them when it sounds. In North America, discussions are ongoing regarding thenecessity to develop a public education campaign on the subject of this new evacuation signal, and whether an automatic recorded message should follow the signal to prompt the public to evacuate. As a first step, we need to ascertain if the public already recognizes this sound as an evacuation signal.
