great videos man....love the commercial hvac stuff. most people do residential so this is super awesome.

Very informative tutorial thank you much Ken, BIG thumbs up!

Got all the information I was looking for! Thanks 🙏 from India 🇮🇳

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.

Great video! YOU'VE EXPLAINED WAY BETTER THAN MANUFACTURER THEMSELVES

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.

Great video I learned a lot

Thank you for sharing your knowledge

what a great video. hope u can make a video at least 1080 resolution. thank you

Very good explanation.

A big help thanks.

Good Job.

You can also ohm the leads out to determine an open circuit while you are up on a ladder.

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

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.

are they operate the same like the actuator for airhandmer?

This is the thing in my wall making a bunch of racket all the time :O

what the name of that tool he use to turn the motor manually great video

That switch is a dry contact correct?

Nice

Good video, I as well have a video on my channel. Cheers

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?

I have an important question. How to disassemble it. I am talking about the one you was testing on video

What does setting it to 50% do, that closes a switch for what exacly?

How do you wire a 12p volt fire damper with a single poll toggle switch plus tap into fire alarm relay

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.

I didn't get more out of the video... 2 wires are they control circuit and elec circuit...

I thought it's 24 volts.

Larry Tuliao , no. 120 model means 120v.

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.
