Great presentation thank you. I know the only thin missing is the two exhaust fans need to turn on even if the switch entering the kitchen is off position,
easy accomplished by running a wire from the first micro switch on the normally open side to the first cont actor bovine hot leg.or the second cont actor bovine hot leg will do the same.
In case an alarm goes on, the first micro switch will send signal to the firs two cont actor turning the exhaust fan on even if the kitchen switch is off.
thank you for this great video.
Correct he did miss this important part on his explanation!!!, I know you know better the this guy making videos 👍🏻🙌🏻😆
Very educational. But what I don't understand is what happens if your switch is in the off position and a fire occurs? How will the exhaust fans turn on? Where will the power come from?
This is why its preferable to go with a direct control ventilation system. Captiveaire as well as some other make a system that has temp sensor and/or firestats, depending if its ansul,Tank, or Core, in the hood. The fusible link will still activate the fire suppresion system in this scenario but fans will not operate. DCV system, when the microswitch activates, will power the exhaust fans automatically, no need for a switch to be on
If your switch is off and your system goes into fire mode, what turns the exhaust fans on? Should be controlled by one of your NO micro switches, but i don't see the wire. Thanks.
the micro switch on the fire system.
This is awesome. Just exactly what I need for the owner to understand the work needed for his restaurant.
Thanks,glad it helped.
Hi do you have a diagram for installing regular commercial hood /fan
Electrical part for it
We need a switch for the light with 20am breaker
Then sensor
And fan switch
Is there some kind a diagram one goes where ?any information will help this is the first time I’m doing it.
I’m a journeyman for three years
If you can give me some advice, I would appreciate it
this is a great video...is it possible you can do a video on a single pole for 1 Exhaust 1 MUA? greatly appreciate it.....or if you can , a diagram would be good as well. thank you
Thanks for watching! As far as the 2 prong vs 3 prong outlets the only practical way to get a true ground at each recept would be to update the wiring.
Love ur video. Just the l lyrics on the way
0:35 What will happen in case of fire?
I am truly amazed how beautifully and clearly you've explained that issue! I am speechless... What a skill! I feel that I could understand a rocket science if it was explained by you. I salute you Thank You from the bottom of my heart
Teaching standard: pure perfection
Correction: What happens if your switch is in the off position and a fire occurs? How will the exhaust fans turn on when the fire suppression is activated?
The make up air is what get shut down in case of a fire. I know what your asking but the systems are not required to turn on the ex fans automatically.
The exhaust fan is required to turn on automatically.
I also would like to know. I am doing the restaurant from hell. 9 contractors total with 4 shunt trip breakers. I'm getting a back feed when I try and add the override. I close one and it hold them all closed

Hi , there . I have a question about when the Abdul system is triggered, I can see on your diagram that light & outlets all cut out by microswitch. But you didn’t mention how a the Exhaust Fan will turning On ? Since the the switch is on open position.
You are missing a wire, when the Ansul system trips and exhaust fan switch is off, the fans will not turn on. Code requires exhaust to turn on no matter what position the Fan switch is in if Ansul System trips
Wasn't too bad. It always helps when the wires are marked and a diagram exists.
Hello is there any way i could have a phone call with you?
Please use my email address in my channel description with your phone # and a brief description of your purpose for the call. Thank you!
am i correct if you connect the normally open of the first shunt switch to the ex fan contactors this will ensure the ex fans are on when the switch is off in an emergency state??
i agree seen a house with k&t that had 16 gage stranded wire run to every ground screw on each receptacle then to the basement all stuffed into a large wire nut with one wire running to the ground screw in the disconnect for the watter heater that was feed with modern 10/2 from the 20 year old 100 amp FPE panel that had sort pieces of romex going into j boxes then to the k&t all this covered with insulation so other than the FPE panel everything looked fine and tested as grounded
Do you do any house rewiring? Got to replace a lightswitch with an outlet, and in the junction box above it I got a few wires, Black, Black, Black, Black and Black.
I assume they are soldered and wrapped in tar paper (no terminal block or twist on connections or anything, wiring from the early 1920s). Didn't take a too long look at it, just made a mental note it is not a five minute project as I originally thought.
What would you do? Out with old crummy in with new shiny?
Great diagram. Thanks but have a couple questions. One.. in your drawing it appears the hood switch must be on for the exhaust to be running even if the Abdul actuates. Is that acceptable? Also it looks like you could tie the Mua and branch circuit/lighting contractors together on the control circuit and avoid using the second ansul device contacts. Sound correct? Thank you!
Do I tie into the cr2 and ar2 to kill the N/C contactor for appliances under the hood?
Ignorant, but honest question: Why do the exhaust fans remain on in the event of a fire (when the fire emergency button has been pushed)? Wouldn't that cause more air flow, which would increase the size of the fire?
The purpose of the ex-fans running during a fire is to reduce heat and smoke. I understand your thinking,
but the fire department tells me they want the smoke out.
Thanks,I appreciate your comment.
Ap nozzle how much area's covered by the range ?, Please tell me guys.
Kool that makes sense , I bet you had one hell of a time figuring out what is going on in that control can
This is incorrect. The power switch gets wired after the micro switches. You can use one micro switch to control all contactors. In addition, you need to run a wire from the NO (Normally Open) micro switch to the hot leg of the Contactor coil for the exhaust fans. This guarantees that the exhaust fans turn on when they are off or remain on after the system trips. Also, the Hood Lighting will not be controlled by the switch if it's on the same Contactor as the appliance circuits as shown.
can't see your cursor !!!! more confusing
can I make one like this control be arduino
As long as the parts you're using are rated for the requirements of the equipment.
Very nice audio and visual mate.
Long time electrician here and you taught me something !
How would you update this wiring for an ansul system which i dont see here.
very helpful, thank you!
You mention turn the $ on what switch ?
The light $ or must be a separate $
