How It Works

The DR-01/SS uses an electromagnetic holding force to retain a fire door in the open position. When power is removed via a fire alarm interface or manual release operation, the magnet releases the door, allowing the door closer to automatically shut the fire door and help prevent the spread of fire and smoke.
