Description
Product Description
Castle Combined Fire & Smoke Dampers perform dual function — both fire damper (UL 555) and smoke damper (UL 555S) in a single unit. Spring-return motorized actuator with 72°C thermal fusible link as backup. Provides fire compartmentation AND smoke control at duct penetrations through fire-rated barriers — eliminating the need for separate fire and smoke dampers.
Dual Certified
Single unit meets both UL 555 (fire) AND UL 555S (smoke) — eliminates need for two separate dampers.
Triple Protection
Motor closes on smoke signal + thermal link activates on heat + spring closes on power loss.
Space Saving
One damper instead of two — reduces installation space, cost and maintenance requirements.
Dynamic Rated
Closes against 2000 fpm airflow — system can remain running during fire event.
