Johnson Controls DMPR-RS312 Fusible Link ensuring a long-term specialized sealThe Johnson Controls DMPR RS312 is a high performance 212 degree fusible link engineered for critical fail safe activation in fire and smoke damper assemblies. As the direct DMPR RS202 replacement, this heavy duty heat responsive device is essential for maintaining the UL safety rating of FOVHN series fire dampers. In the event of a thermal excursion reaching 212? F (100? C), the fusible link melts, triggering the immediate mechanical closure of the
