Johnson Controls DMPR-RS311 Fusible Link The rugged Heyco-style design allowsAs a direct replacement for the legacy DMPR RS201, the Johnson Controls DMPR RS311 is a critical fire safety component engineered specifically for FD 1300 Series dynamic multi blade fire dampers. This 165 degree fusible link is designed to provide thermal triggered closure in high velocity HVAC systems, ensuring compliance with UL 555 and NFPA 90A standards. The DMPR RS311 functions as a mechanical release; once ambient temperatures reach 165F (74C),
