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 or a temperature sensor which typically provides signal to the actuator once the temperature reaches set limit. The actuator then moves the blades in closed position & shut off the fire from spreading in other premises. 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.
