Life Safety Dampers

This device is actually used inside air transfer outlets and air ducts of the smoke control or air distribution system. It is specifically designed to automatically close whenever it senses heat. Additionally, it interrupts the migratory airflow, stops flames from spreading by obstructing its flow from the place on fire to the unaffected places. Fire Dampers are operated by a fusible device, which is typically a melting link. They are designed and equipped with a fusible link which holds back the blades in open position till the link melts. When the melting point is reached, the blades then close and prevent the flame from moving from the affected location to the corresponding location. These devices are generally installed near the wall or the floor, right at the point where the duct penetrates the wall for retaining the integrity as well as the fire rating of the walls or the floor.
