Global Tampers

Go and pick up the toys.

H&S risk assessment - to high a risk of slipping in your discarded sour grapes!

This may be the point to say, please use the ignore features. It works well.

I dont understand the point unless the cables are not labelled?  If you have metered the cables found the one with high res then look at the label on the cable then go investigate seems the most logical way to do it

I see arfs point as usefull for when the loop is ok when you get there. You can then tap passives, joints etc to find the issue this way. I can see its useful when the meter shows its ok at the panel/input

Ahh so when the circuit is not high res ......but how do you know which circuit to test I suppose you put them all through the tamper return. But then surely leaving the system in day mode and tapping passives and joints ect it has teh same effect with less wire moving

I'm lost Pete, i was meaning old school audible only?

interment tampers can be caused by lid contacts not being adjusted properly, just on the cusp, i found one this that way, was in an airing cupboard j/b, heat from tank changed it slightly.

the important part is the meter reading comparisons against the previous test, but this method allows you a further test to know exactly when that lid contact is closed or opened.

unless you have an assistant, a pretty tricky test on a meter if you can't hear the test buzzer as you go around.

a variation in smaller buildings is a cheap piezo tone buzzer across the tamper pair, tamper opens current go's through buzzer and it sounds, can be heard over some considerable distance.

Its simple where there is a intermittant tamper fault Arf suggests first metering the tamper circuits, asuming that none have high res put the circuit in series with the bell tamper then go tapping stuff till you find the fault. I reckon if you leave the tampers where they are with the panel in day mode you can do the same as arf suggest when you find the dodgy circuit the panel will go into tamper

I see! Your not talking about finding the fault you are talking about making sure its fixed

Ignoring the previous drivel.

 

Use another method, like suggested above, If it is a legacy falling apart last thing you want to do is disturb more items.

 

And fit a graded correctly tampered JB, not a leaf spring type if unsure. Job done.

Not mess about for more time than it is worth.

 

You forget Arf does not charge for this. Or have overheads, Hence he can afford to potter about for a few hours.

i always make sure its fixed .

joking aside - no, but your are getting there though you need to test the various lid tamper adjustments as well for changes in resistance that indicate either you have cleaned the problem contact or it has degenerated. using the panels tamper feature it won't reset (unless you go back to the panel), so a less useful option.

remove any lid siren ceases, close lid siren sounds, using slow actions you ill know its adjustment precisely, if ok move onto next one (quickly if coarse ).
