Belimo FSTF24-S On/Off Spring Return Fire & Smoke Actuator 24V

The Belimo FSTF24-S On/Off Spring Return Fire & Smoke Actuator described in this article is an essential component used in fire and smoke damper solutions in HVAC systems. This actuator has a Nominal voltage of 24V AC/DC and has a control type of On/Off. Similar to the above actuator, this actuator uses a spring return feature in case of an emergency. This makes the actuator safer when there is power failure since it has a predetermined position for stopping to avoid the spreading of smoke. It has two extra switches for other control and detecting functions as well. These include no need for regular maintenance, small size, and easy installation with reduced operational cost leading to high system reliability.
