ACDSV acoustical smoke vent designed to guard against noise intrusion while providing the security of automatic smoke venting

February 7, 2022

BILCO's ACDSV acoustical smoke vent is designed to guard against noise intrusion while providing the security of automatic smoke venting. Acoustical vents feature industry-high STC 50 and OITC-46 sound ratings. They are ideal for concert halls, theaters and other interior applications that require limited noise from the outside. Vents are available in steel construction and in a number of UL-Listed standard sizes.

Automatic Acoustical Smoke Vent

Type ACDSV

Standard Features and Benefits

STC-50, OITC 46, and ISO 140-18 (rain fall - 37.5 db) sound ratings. (Read selecting the proper sound rating for Automatic Smoke Vents)
Thermolatch® II positive hold/release mechanism ensures reliable vent operation when a fire occurs.
Automatically releases vent covers upon the melting of a UL-listed 165°F (74°C) fusible link.
The curb-mounted fusible link housing allows the latch to be quickly and easily reset from the roof level.
Engineered with powerful gas spring operators to open covers in snow and wind conditions.
Gas springs have integral dampers to assure the covers open at a controlled rate.
Fully insulated and gasketed for weather-tightness.
Constructed with corrosion resistant materials to provide many years of trouble free, dependable service.
Available in a number of standard UL listed sizes.

Guide Specifications

Material: Cover is 14 gauge (2 mm) G-90 paint bond galvanized steel.
Covers: Brakeformed, hollow-metal design with 4" (100 mm) mineral wool insulation, 5-3/4" (146 mm) beaded, overlapping flange, fully welded at corners, and internally reinforced for 40 psf (195 kg/m2) live load.
Curb: 12" (305mm) in height with integral capflashing, 4" (100 mm) fiberboard insulation, fully welded at corners, and 6-7/8" (175mm) mounting flange with 7/16" holes (11mm) provided for securing frame to the roof deck.
Gasket: Extruded PVC gaskets permanently adhered to the underside of the cover and the top of the curb.
Hinges: Heavy-duty pintle hinges with 3/8" (9 mm) type 316 stainless steel hinge pins.
Latch: Positive hold/release mechanism controlled by a single UL-listed 165°F (74°C) fusible link with a separate latching point for each cover. Designed to hold the covers closed against a 90 psf (438kg/m2) wind uplift force. Provided with interior and exterior pull release cables to manually open vent covers.
Operation: When acoustical smoke vent is released, high performance gas springs open covers against a 10 psf (49kg/m2) snow/wind load and lock covers in the open position. Gas springs have integral dampers to assure a controlled rate of cover opening and have a cyclic durability of 50,000 cycles.
Performance Ratings: STC-50, OITC 46, and ISO 140-18 (rain fall - 37.5 db) sound ratings. UL-listed.
Comply with UL 793 and UL 790 Class A (burning brand test).
Finish: Alkyd base red oxide primer.
Hardware: Corrosion-resistant gas springs and hot dip galvanized steel stop cables. All other hardware is zinc plated/chromate sealed.
