The Type ACDSH double-leaf acoustic fire vent is ideal for installation at concert halls and theatres and other applications that require a high level of acoustic protection as well as fire and smoke ventilation.
Available in a number of standard UL listed sizes, the automatic vent effectively removes smoke, heat and gases from burning buildings, helping firefighters to bring the fire under control.
A Thermolatch®II positive hold/release mechanism ensures reliable vent operation when a fire occurs. The vent covers are automatically released in the event that the UL-listed 74°C fusible link mounted on the curb is melted.
The vent has gas spring operators that are capable of opening the covers in snow and wind conditions. They have built-in dampers to assure smooth opening and eliminate operational, roofing or structural damage.
The Type ACDSH double-leaf acoustic fire vent has STC-46 acoustical sound rating. It is fully insulated and gasketed to protect against adverse weather effects.
