If you're unsure on checking resistance then maybe opening up PIR's and alarm panels isn't for you after all.

Hello, No i am ok at opening pirs and the control panel. Its just i am not 100% sure on testing resistance with the multimeter. I work with computers so i know how careful you need to be when opening them up and adding devices to them. I take its the same for alarm systems except you can have bare wires which could short if you remove the wires from the device.

If I followed you correctly you have a six core from your panel to a pir then of to another ?.

As a temp fault finding test why not take the white/green out of the tamper at the first pir. Join it straight through to the other pir, then put the wht/gn into a cct at the panel. This should make fault finding a lot better.

To sum up, common pos & neg from panel to both pirs

blue/yellow to first pir

white/green joined through at first pir,giving you a cct pair at

second pir

Hope this helps as a temp fix, remember your pirs will not be tamp protected.

Hello, Yes i think i understand what you mean PJF is removed the tamper on both pirs so i can split the second pir to it own zone using what use to be the 2 tamper wires. Also making sure to remove any series wiring.

That was mean.

Instead of rewiring, you could change the 2 pir's that are on the same zone to a latching type, the ones you already have may even have this facility.

As long as these 2 pir's are not on the exit route it will not cause you a problem, you may have to fit a 'reset' switch if your panel does not have a latch reset output.

Still easier than rewiring tho.

Hello, I don't think they support latching. I am sure that one does not have it and i don't think the other has it too.

thankyou

Try spliting the two P.I.Rs into seperate zones if you only have 2 alarm wires avaliable then see if you can wire them deol, or seol-o/c tamp, depending on what alarm system you have. Then if it false alarms again then you will know which device it is ,then i would probably change it.

Hello, I don't ...

Hello, just had to say that your hello's make me smile. Goodbye
