ACOUSTIMAX™ SMOKE VENT
Model(s): BSVZ/BSVY
GENERAL DESCRIPTION
Acoustical smoke vents are primarily used in theaters and performing arts centers because
they block the intrusion of exterior environmental noise. Acoustical smoke vents provide both
sound control and thermal performance. The SVZ has STC50/OITC 47 and ISO 140-18 Rainfall
36.7 dB sound ratings. The SVY has STC50/OITC 39 sound ratings.
The AcousticMAX sound rated series meets International Building Code IBC 1207 sound
transmission class requirements and is used in high end theater applications as well as in
building applications where condensation is a concern.
Sound transmission is tested by an independent lab accredited by the U.S. Department of
Commerce and the National Institute of Standards and Technology for conducting official
acoustical test procedures for sound transmission class (STC), Outdoor-Indoor Transmission
Class (OITC), and Sound Insulation of Building Elements (rainfall dB) according to the following
tests:
• ASTM E90 Laboratory Measurement of Airborne Sound Transmission of Building
Partitions
• ASTM E1332 Standard Classification for Determination of Outdoor-Indoor Transmission
Class
• ISO 140 Acoustics Laboratory Measurement of Sound Insulation of Building Elements

Installation, Operation
+ Maintenance Manual
Acoustical smoke vents are designed to open
automatically to provide emergency smoke and heat
ventilation. Prompt venting during fire emergencies is
essential for the safe evacuation of occupants and for
effective fire-fighting conditions within a building. The
smoke vent is not intended for use as general-purpose
building ventilation devices. International Building
Code (IBC) requires smoke venting in a variety of
applications including Section 410 for stages and
platforms, Section 910 for factory and storage
occupancies .
