Acoustical Double-Leaf Smoke Vent

In the event of a fire, a smoke vent can help reduce the spread of fire and ventilate smoke, giving occupants more time to escape, making it a valuable investment. BA-ACDSV Acoustical Double Leaf Smoke Vent offers superior ventilation, but it also prevents external sound intrusion in auditoriums, concert halls, and theaters. It also guards against low-frequency outdoor sounds like traffic and airplane noises.

Reasons to Choose BA-ACDSV

Double-Leaf Vent Doors: BA-ACDSV utilizes a double-leaf door mechanism for an increased surface area allowing a more efficient smoke ventilation process, ideal for high-square footage buildings. 

Automated Unlatching Mechanism: Our innovative Thermolatch mechanism allows an automatic latch release that is activated using a fusible link, satisfying International Building Code (IBC 910.3.)  In an emergency, the fuse will melt at temperatures about 165 degrees Fahrenheit (74 degrees Celsius,) activating the unit's responsive double-leaf doors.
