Belimo FSNF24-S-FC S/R Fire/Smoke On/Off Actuator 24V

The Belimo FSNF24-S-FC is a spring-return actuator designed exclusively for controlling fire/smoke dampers in HVAC systems. It uses 24V electricity and has a "fail-safe" mode that automatically closes the damper in the event of a power outage. This vital safety element aids in the containment of smoke and fire in emergencies. During normal operation, the Belimo FSNF24-S-FC receives a signal to open or close the damper, which adjusts airflow in the ventilation system. During a power outage, the spring mechanism acts, closing the damper to prevent the spread of smoke and fire. Because of its fail-safe design, the FSNF24-S-FC is critical for guaranteeing safety and following building requirements in a wide range of applications, including residential and commercial buildings, hospitals, and schools.
