Thanks Clayton, I'm no expert but I always found it difficult working with duct detectors. Once I figured them out I had to share, that way the next guy doesn't struggle like i did
@@HVACRVIDEOSdeffinatly a good video once you get the trick of them you know it forever I was just amazed watching you're videos and come across this and I understood it so well
I am going live on RUclips this evening 1/7/19 at 5:00pm pacific standard time to discuss my most recent uploads, come on over and check it out ruclips.net/video/UXpVzsY0gzc/видео.html
Very intresting how fire detection is done in the USA. Here in Australia we have the same enclosures that sample air that goes through detectors. Except we have all fire dectetion on one panel that we call an F.I.P (fire indicator panel). All the detectors are connected in a loop to the panel and the fip is connected to the emergency services, and sometimes connected to security.
It depends on the job and also on the local fire code/jurisdiction. I've installed duct detectors that are basically just the smoke head, that's addressable on the facp, with a separate relay module that the hvac tech will connect to shut down the unit. I've seen these other ones that have their own control board that are installed by the hvac tech and we (the fire alarm guys) just hook up a monitoring module. Still always need a relay module so the facp can shut down the unit regardless of the duct smoke detector.
New Alarm panels are making it easier to pinpoint alarms/troubles.... all that good stuff by using addressable devices with unique ID numbers. IE: instead of “Trouble Zone 16” it would be “Trouble RTU 3 Return” or whatever name they set to the device.
Just experienced a trouble condition on a RTU. Started Friday before Christmas (2018). Part took a week to come in (Christmas eve/Christmas Day included in this), so I had a beeping alarm panel for a long time. Medical building. Even had a fire inspector breathing down owner's neck...so the supply houses have to do better especially if this is a common issue.
have them order more and keep a spares in stock on site? assuming they have a building/multiple RTU's of same device/s. why should multiple HVAC companies have to keep them in stock, when possibly it's older and only one customer uses that model........ tossing a bone to HVAC corps and beating the heads of building owners seems very fitting in the above case ;) maybe they should be required by fire code to keep spares in stock (vacuum pack sealing works well)
Always great video!! Thank you Chris! And happy new year! And have a question for you So A/C units are goes by tons But why refrigeration units are goes by horse power? Why? Thanks in advance!
I deal with 1 national chain retailer that of all the name brand stores out there they have the most issue's dealing with smoke detectors and the wiring Centerpoint. The note worthy point is they use xyz alarm company who then subs the work out to multiple local alarm companies. None of it is wired the same and when working in multiple state's I'm not allowed to touch their wiring, and yet we are dispatched instead of the alarm company. With this said 9 time's out of 10 the issue lies with alarm wiring and yet we're required to replace smoke detectors and the wiring point. In a store with multiple units there's always a relay present to globally activate the entire network and that relay can be a cause for trouble as well. Another part the alarm company is responsible for.
No not really I did another video that explained a bit but I did not go in depth on the other contacts ruclips.net/video/-Oh-aM3gOZY/видео.html I will work on a in depth video explaining the other contacts
How would you disable a duct smoke alarm that has a bad board and is preventing the buldings fire alarm from being reset after a accidental trip of the alarm?
Dawg I set one off yesterday 😢..I didn’t have 24v on red but I had it coming out of my transformer so I traced the issue back to the smoke detector because that’s the only thing I could think that would interfere with the 24v signal..I did in fact have 24v at the smoke detector but not coming out of it so my dumb ass decided to jump the detector out which in fact called the fire department 😂..I was cleaning up and not even kidding I see a stood up from behind a unit only to see a fireman 👨🚒 walking towards me across the strip mall roof 😭
Any idea why about every 8 hours the light will turn red keeps happening to me. I acknowledge the code reset it and even cleaned out the tubing in the detector it's self. Any ideas ? Thanks
CHRIS CAN YOU HELP ME OUT ?? I’m trying to get a better understanding with these things and made a simple setup with just the detector.I have a system sensor d4120 So to test things out I have 24v on 9,10. On 4c a resistor to 3c. 14no connected to 5no I have a green light flash every 5 seconds on the head and board. The thing is the normally open supervisor contacts are closed for 35 seconds on start up and then open but show no trouble. When I do go into alarm the red light is lit and contact 4c and 5no are closed but no changes in the other contacts. I thought it was the board itself and tried another one but I have the same issue. Can you help ? Edit . According to the instructions on status indication listing ( I’m looking at 3 and 14 ). On startup they’re closed, Maint they’re closed and open on trouble open. On start up 3,14 are closed and open after 30 seconds. I’m open I should have and amber light but I don’t. The head and board flash green. So no alarm, no trouble but my 3 and 14 contact are open.
Im telling you Buddy.... This is one very very Great video. From Idea to execution of the lesson you made it work. Keep up the good work !
Worked on fire alarms for 4 years dealt with this kinda stuff all the time good video

Thanks for this video Chris. I deal with duct detectors at my building all the time
Thanks for watching Paul
Fantastic video! I am ready to watch Mission Impossible now.
Thank you for posting this video. it was hard to understand when. its streaming live. Appreciate it sir !
Good vid. Also note that many of the smoke heads are addressable on the back so the fire panel knows which one went off.
Great point! Thanks for watching!

Its the same here we connect our detectors in a loop and they terminate in the fire panel

Thank you and happy new year to you too!
Cristal clear explanation.

Yeah I keep them in stock in our shop

@@HVACRVIDEOS Too bad our service provider doesn't. Not a small company either.
Great explanation 🏅🏅👍
Thanks
Always great video!! Thank you Chris! And happy new year!
And have a question for you
So A/C units are goes by tons
But why refrigeration units are goes by horse power? Why?

Very very good!!!
Thanks bud
do you have a video explaining the other contacts. ie the second row
No not really I did another video that explained a bit but I did not go in depth on the other contacts ruclips.net/video/-Oh-aM3gOZY/видео.html I will work on a in depth video explaining the other contacts
These Duct detectors need a pressure difference between the sampling tubes to work. What does the duct ends look like?
Oh nice!

most important thing, always follow local fire codes ;)
For sure!!
