You still in it? 11 years is a long time.

Hey joe, just out browsing trying to learn new stuff. I’ve been a commercial industrial electrician for over ten years and have done very little F/A. I will be very honest I’m not super confident in this area. So That’s why I’m watching your videos even though I don’t do F/A there are aspects I feel can definitely still benefit me in other areas. This may be a dumb question but the resistors y’all put in at the device between the wires (and I know sometimes you just put the resistor back at the module/panel. Can you please explain to me what the purpose of that resistor is and how it is providing obviously something crucial to the success of this installation . I mean I have an idea what a resistor is, I just never understood what it does in the FA scenarios . Any knowledge or input would be greatly appreciated. Thanks joe.

Mike, the purpose of the resistor is to supervise the integrity of the circuit. The panel is designed to "see" the resistor. By adding it to the end of the circuit, it provides proof that the circuit is still fully intact. If someone were to cut a wire, the Panel would no longer "see" the resistor (I.E., no current would be flowing) and so the panel would go into trouble, indicating a problem on that circuit. My first 2 videos should clear it up.

Joe Klochan thanks for the reply joe. Appreciate you taking the time and I will definitely watch those tonight. I guess my next question is if the resistor is not there , there is still current returning back to the source and the panel acknowledges that still correct? I’ve done some control work as well so I have a little bit of an idea what an input is. So it is the AMOUNT of current the panel detects when there is a resistor ? Ughh lol I know there’s just knowledge I haven’t attained yet (which is why I’m still missing something ) lol but I’m gonna go watch those other videos.

That's a good question, and it depends on the type of circuit. If it's a horn strobe circuit, there would be no current flowing through the circuit at all if the resistor isn't there. Ever horn strobe has an internal diode preventing current from flowing through the device in a standby state (that is, when the panel isn't in alarm). So the diodes prevent current from entering every horn strobe. Then when the panel goes into alarm, the polarity reverses at the panel, and so the current can then pass through the diodes. On an old conventional smoke detector circuit, it works more like you suggested. The smoke detectors do draw an extremely small amount of current, but not enough to affect the panel's ability to supervise the circuit using the EOL resistor. My first several videos hopefully do a better job of explaining this than I can via text.

Joe Klochan So I watched the first two and you were absolutely right ! I totally have a good understanding of what the resistor is for FINALLY!!! Can’t wait to continue on with all your other videos! Love learning ! Thanks for all your help and for taking the time to help me !! 👍🏼👍🏼👍🏼

You wrote the digital book. Number One on my New York (actually L.A.) Best Seller list. Wish we had digital video back then, I would have done the same.

Depends on the model of the waterflow. Buy a security bit set (Klein makes one). That covers most of them

It does not. The whole point of a monitor module is to interface between an intelligent panel and a conventional device. If you have a conventional panel, conventional devices connect directly to the zones.

If it's a class B loop (circuit goes out but doesn't come back), you'll have a lot of "missing" devices. Different panels show these troubles by different terms: "missing", "invalid reply" "no answer" "comm fail", etc. If it's a class A loop (circuit goes to each device then returns to panel), you may have a single trouble that says something like "style 6 open", "loop break", "class A trouble", or something to that effect. If it's a class A (style 6) loop, you can disconnect the circuit at the panel and meter for continuity between the two negative legs of the circuit, and between the two positive legs of the circuit.

I don't know, what model beam detector. Do you have a link to the installation sheet?

@@JoeKlochan i only have the model number

Take his videos as the GOOD BOOK ... so much easier to understand.

I thought the resistors were only for the FMM's ? I don't think he showed a resistor on a pure addressable device ... or did he?

Yes class B is conventional & class A is addressable system

Yeah I think you're right. I made this video a long time ago, and I've never wired one of these things class A. I always thought the resistor went at the module, but recently I think I came across a scenario where I found out that wasn't the case.

I cover that in another video. Look up the video on control modules

syed ashar imam if you control directly from the panel, that is, from an onboard NAC, you would not use an FCM.
