Babcock-Davis easy-access smoke vents are designed
to open automatically when a fusible link reaches 165 degrees F
to provide emergency smoke and heat ventilation. They are spring
operated with shock absorbers to slowly open against wind or snow
load. B-D smoke vents can also be equipped to open electrically.
Prompt venting in case of fire is vitally necessary to the safe
evacuation of occupants and effective fire-fighting conditions within
a building. Proper venting will limit smoke and water damage to
a smaller area within a building.
