Motorized Smoke Damper – AMSD

Motorized  Smoke damper is a device installed in an air distribution system or an air transfer opening designed to close automatically upon detection of smoke, interrupting the airflow and thereby restricting the passage of fire in the process. The location and installation procedure of fire dampers should be in accordance with the widely accepted and recommended standard, NFPA 90A – Standard for the installation of Air-Conditioning.
