How to do a ground fault check with your multimeter at the FACP

This video shows how you can produce a ground fault at the FACP by placing one of your leads from the meter on either the + or - side of the NAC wires and the other lead on a ground source so you can produce a ground fault trouble on the panel.

He is creating a ground fault condition to see if panel will recognize an actual fault due to field wiring issue. If panel does not recognize a true fault condition. Then most likely. Then the ground reference was removed or cut depending on what kind of system your serviceing. For some techs that are just now getting into full time service work. The diode check is very effective on troubleshooting modules on an SLC loop or an AV circuit with a bad device. The way he is creating a ground fault is very smart.
I am an old school fire alarm technician that services conventional and addressable systems. Even serviced panels that use EOL DIODES instead of resistor. That's how long I've been doing this crap! BUT I love what do.
Just remember, everytime your installing or service a fire alarm system. Your saving lives!!!!

Great video. Can you more different tests that can be useful to know. Further, could continuity or ohms scale on the meter have the same result ?

Hello, how are you? I'm Joverci Ribeiro, I live in Brazil, this video helped me a lot, I would like to know how I can generate the following flaws in the notifire panel:
Open Circuit Failure;
Short Circuit Failure.
I need to put these tests in the reports, I will be grateful for helping. thankful

Is that an NFS-320? Is it possible to disable ground fault detection on it?

wait, did I miss something here? were you just testing to see if the panel would recognize a fault? I thought you were testing an actual fault?

Excellent, short and simple. Learn something new today.

The meter was set to a DIODE TEST (i.e., gives a low resistance path through the meter to ground when connected)

I got a 4004 that I got for a mini demo system and it has a ground fault and I just going get some stuff for it like resisters for my nacs and zones

[GTVAlfaMan]

Was the Fluke set to resistance for this test?

[GTVAlfaMan]

So what exactly did you set your multimeter to?
Infinity ohms resistance or continuity?

[khalilansari]

Gent fire alarm panel how many types of fault and how we will rectify.

which company's FACP u are tested here ?

Wording should change to "how to create a ground fault with a multimeter"

[trentthomas]

Will this strategy lead me to what circuit the ground fault is on?

[justindaigneault]

couldn't you just use a piece of wire or anything conductive from one lead to a ground source?

[venugpal]

You can't do this. Either you should off the panel or remove the cables, which you want have to test ground fault.

[MrMppeters]

Really? "Arrow pointing to the plus sign" It's called a "diode"

[guesswhomartin]

Maybe I'm slower than everybody here, But aren't you causing a ground fault ? We're suppose to look for the ground fault, not create one. Take the wires off the panel, And meter for the ground fault.
