Acoustic Smoke Vent | Sep 1, 2006 |
Nystrom introduces the STC45/OITC37, the only UL 793-listed smoke vent in the industry. Nystrom Acoustic Smoke Vents can be connected to a variety of fire alarm systems. The innovative two-door construction offers many advantages over the conventional four-door design. Designed for ease of installation, it requires fewer field adjustments than a traditional four-door model. The composite material in the walls, in combination with a specially designed gasketing system between the cover and the curb, provides maximum sound attenuation.
