Alarm Fault On A Veritas R8 Plus

[gym_rat]

educate me, how is that relevant on induced ac?

 

the same reason you don`t need bonding if the water supply to your house is plastic - no connection to earth

 

 

 

and on an esoteric level, it`s the act of passing through the metal of the case that actually creates the induction - think about opto isolators on the old ABC units

 

 

 

thats if induced AC actually mattered (which it doesn`t LOL)

[james.wilson]

Are you saying that cos its plastic any induced ac into the wiring is irrelevant? If so i disagree. While its probbaly not much of an issue if its constant in theory a switching load and as such the induced ac changing will affect the level of ac on the system. May or may not be a problem.

 

While i accept that induced ac is rarly an issue in pure theory terms it is. While id also accept that most decent panels have good enough filtering on their input stages some do not and (when we used castle) have seen an act 1313 work its magic.

You know it does.

 

 

And JW a plastic panel IS less susceptible to induced AC.

Not immune, but generally they are fine.

why?

I can see that it wont have a route to earth but just as susceptible surly?

no buddy, what I`m saying is because it`s plastic, there will be no induced AC - there is no return path to earth see?

[james.wilson]

So to be clear.

A metal panel is more likely to have ac noise on it?

the only time you`ll see it on a veritas R8 (or any other plastic panel) is when your test meter completes the circuit between +ve DC and earth.

 

 

and you wonder why I say it`s a myth LOL.

I shall sort it one way or the other. The inductance point I mention, Texecom tell you not to install alarm cable next to power cable. You must know this, The cable has a magnetic field around it. (thats how these cable detectors work) If the alarm cables are next to power cable then it can pick up signals.

Gets ready...

Would buy popcorn, but not after last night.
