    What are you suggesting, he's over the hill?
    If you don't like trucks, stop buying stuff.

    So wouldn't be an inconvenience then?


    Seems ok for now but we'll see today after having a shufti yesterday. I'll arm it & go out for the day & see what transpires & will either be greeted by ****ed off neighbors or a burnt down house on my return.


    Should I be worried, as now putting up with his developing Vineyard where they have spread Blood & Bone all over.

    I thought the sewerage was playing up until I saw a bloke on a tractor with a Hopper on the back making merry hell. Wind is from the NW as well.

    Well back in again @1538 hrs.


    No siren Box light flashing nor any faults listed.

    Can still smell the Blood & Bone, Brad. I don't suppose you have an answer to that bloody pong?

    Update to any interested parties.


    Bloody thing screamed at 0330 yesterday. Bloke came, still couldn't find anything positive. Replaced Optex PID. Today went off again & 0530 Last thing to replace is the cable to the main box, coming back next week to do.


    Have a blue unused Data Cable between the two buildings so going tp nick a couple of wires in that. Bit of a bugger, the back roof has to be lifted so hope the forecast rain is going to hold off.

    The cable was installed waaaay back but was never used once we got WiFi & now Wireless Broad Band.

    Bugger. That's kinda why I suggested just putting the resistor across the cable and leaving it for a day or so to rule out the PIR.

    It's not a great thing to do, but if you find you have a single damaged core you can often use the black (gnd) as a common and run it with 3 wires. Does depend on the panel input configuration though.

    You can use Cat-5 if it's there. Issues *can* come up with volt drop on the power pair and it's often good to use 2 paralleled pairs for power if you have to use Cat5. The Optex doesn't consume a whole lot though.

    There was a Resistor there already, Brad.

    Their specs say AWG22 1700' up to AWG18 9350' @ 12v. Here it would be a MAX of 50' but I take your point & if there are more spare wires I'll make sure he uses those.

    Thank you for your comments.

    I know. I suggested popping the top off the PIR and putting the resistor directly across the cable. Ie take the detector out of the equation. You have 4 potential sources of alarm. Faulty panel (low probability), faulty cable (much higher probability), faulty detector (not at all unheard of) and something environmental (heat, insects, whatever).

    A binary search of the 4 starts in the middle. So you put the resistor on the end of the cable without the PIR in circuit. That points either at detector/environment or cable/panel and go from there. If itís the cable/panel side you then put the resistor in the panel with the cable disconnected to rule out the panel, particularly if itís difficult/time consuming to recable.

    I'm not sure our Hearts can stand many more sudden alarms in the night & your method would entail actual testing over a few nights, right? The internal screamer is within 10' of the bedroom door.

    We have had rodents of some sort, Mice, Pterodactyls, Rats etc in this roof space previously, not just with the alarm system but with the phone. We inherited those from the previous owners & it is still an ongoing exercise to get rid of them. The buggers seem to thrive on fallen Walnuts, Quinces, Pears, Apples from the previous seasons.. They get to them before I can. The buggers transit through the Stud wall then to the roof space. Theoretically impossible since the stud wall sits on a concrete footing. But if there is some weak point of entry they will find it, & have.


    I'll put the above suggestions to the Tech when he is here again.

    Again, thanks.

    Disconnect the siren and screamer until itís sorted. Diagnosis in silence other than a flashing strobe and beeping keypad.
