Having dealt with Belimo and their actuators, I can tell you it is really hard to win a battle with them over a bad actuator. If you have a problem with an actuator, they want you to send it in so they can say there is nothing wrong. I used to test fire, and Fire Smoke Dampers on a heated Wind Tunnel. Handy hint: if you have an actuator fail, do a static torque test on the damper and then do one under airflow. The actuators should tell you how many inch pounds of torque it can handle. It is printed on the housing. If the torque is too high, it can break the gears, they are powder cast and can and do break. I used to do AMCA and UL testing on fire, fire/smoke, smoke and air control products. Nothing like being in a room with 12 dampers during cycle testing. Took about three weeks to get through 250,000 cycles.
I inspect fire dampers and this is the latest in Fire and smoke Dampers the older system is newmattic runs with Air and Fuse links Great video Thank you very much.
These actuators are designed to close fire/smoke dampers in the event of a fire in a commercial building. When the actuator has power, there is a motor that will open and hold the damper open to allow air flow once power is cut [in the fire alarm sequencing] the spring will close the damper and hold it closed to keep fire and smoke from spreading through the HVAC duct work. Fire smoke actuators have to withstand and function in temperatures of 250 to 350 degrees F under various air volumes and static pressures. I have tested up to 8 inches w.g. And it scare the hell out of me. That kind of static pressure can blow duct work out of the ceiling. All of this comes from what happened at the MGM Grand Hotel fire in Las Vegas back in 1980. Lots of people where killed from the smoke that spread through the building. Look it up. I know this because I used to test them.
The video is very good but I sprayed a whole mouthful of red wine on my cat when you said that your shaft was an inch in diameter!, I went from a damn purr to a cat that looking like she thinks I act to hate her
how to lock the damper shaft? for instance 1. motor is not energized then the shaft is at 0' position 2. if motor is energized then shaft rotates and open damper to 90' position, but when again the motor supply is removed the damper goes back to it position.. ? how to keep open the damper?
Ken if it is on fire and smoke damper that is not the correct actuator for that application. What you need is a Belimo FSNF120-S US which has the correct UL rating. If you have any questions please call us at Boston air controls 781-272-5800 we are a Belimo Platinum distributor.
great videos man....love the commercial hvac stuff. most people do residential so this is super awesome.

Got all the information I was looking for! Thanks 🙏 from India 🇮🇳
Great video! YOU'VE EXPLAINED WAY BETTER THAN MANUFACTURER THEMSELVES
Very informative tutorial thank you much Ken, BIG thumbs up!
I inspect fire dampers and this is the latest in Fire and smoke Dampers the older system is newmattic runs with Air and Fuse links Great video Thank you very much.
Very good explanation.
Thank you for sharing your knowledge
what a great video. hope u can make a video at least 1080 resolution. thank you
Great video I learned a lot
A big help thanks.
You can also ohm the leads out to determine an open circuit while you are up on a ladder.
good call, I could have done that as well.
Good video, I as well have a video on my channel. Cheers
What does setting it to 50% do, that closes a switch for what exacly?
thanks
Nice
muy buena explicación
I just wondering what is it for? But now I know... Thanks for this video.& I still have a question is this thesame with the HVAC actuator? Or

I know this because I used to test them.
I have an important question. How to disassemble it. I am talking about the one you was testing on video
I don't know how to disassemble.
At 12:13 why didn't it stop like you said it did? I'm a little confused.
it was not the cam that stopped but the switch opened. you need to listen to the meter and at 50% the meter stops buzzing.
The video is very good but I sprayed a whole mouthful of red wine on my cat when you said that your shaft was an inch in diameter!, I went from a damn purr to a cat that looking like she thinks I act to hate her
I think that shaft is 1/2 inch diameter...
how to lock the damper shaft?
for instance
1. motor is not energized then the shaft is at 0' position
2. if motor is energized then shaft rotates and open damper to 90' position,
but when again the motor supply is removed the damper goes back to it position.. ?
how to keep open the damper?
are they operate the same like the actuator for airhandmer?
can this belimo motorbike be adjusted to make the motorbike spin faster?
I don't know...
what the name of that tool he use to turn the motor manually great video
This is the thing in my wall making a bunch of racket all the time :O
Any more videos on belimo valve actuators?
No, I work on this very rarely.
Good Job.
I didn't get more out of the video... 2 wires are they control circuit and elec circuit...
How do you wire a 12p volt fire damper with a single poll toggle switch plus tap into fire alarm relay
*120 volts
That switch is a dry contact correct?
is this a damper for hvac? looks like it...
Larry Tuliao it is. Bellimo makes damper and valve actuators.
It's an actuator for HVAC air dampers
Ken if it is on fire and smoke damper that is not the correct actuator for that application. What you need is a Belimo FSNF120-S US which has the correct UL rating. If you have any questions please call us at Boston air controls 781-272-5800 we are a Belimo Platinum distributor.
Thank you
for clarifying that. It was not for a fire damper.
KenTraining yeah this is just a spring return damper, when power exists the damper is open and vice versa.
KenTraining by the way i have a query how do you visualize the damper position, in short how do you indicate status/position of the damper ?
Ranadhir kumar the shaft has a slot on in to show position.
KenTraining I'm
I thought it's 24 volts.
Larry Tuliao , no. 120 model means 120v.
Others six wire connection
how to connect switch
not sure what you mean?
@@KenTraining s1 s2 s3
@ 2:04 you can see the schematic drawing. S1 to S2 are N.C.
and S1 to S3 are N.O.
Wiring will depend on your application.
