Texecom D20 PIR Tamper Issue

[leshark84]

Good morning,

I've got a Texecom Premier Elite 88 with 4 Capture D20 PIRs, each wired as EOL on their own zone. They all have selectable resistors and are set to the Texecom setting (2k2/4k7). 3 of them work fine, but one of them goes to Tamper (>100K) when triggered (by both PIR and Microwave) instead of Active (see attached).

If I swap the front modules around, the fault follows the module which makes me think this isn't a wiring fault. All PIRs have the same jumper and resistor settings.

Is it most likely I've got a faulty PIR? What actually causes the tamper to go off as I can't see a contact switch in the unit?

Any advice or tests I can conduct from software or with a multimeter would be appreciated!

Thanks

Try taking off the jumpers and check for good contact ( no bent pins )

It's one of those devices with the slider to select the correct resistors. The jumper settings I referred to are to turn on the CloakWise/LED etc. Thanks.

Ok ….run both sliders up and down , then reset to correct setting and re try , hold two devices side by side ….. see if any thing is different it’s been know for Texecom to miss something off ….lol

whats the resistance showing back at the panel with device not activated?

as it follows the device and not the zone when swapping modules, the logic is the device.

You can try the slider in a different resistor position and try and select that on the panel.

I am going to guess board isn't right possibly and selecting a different resistor value, and same on the panel should confirm if the device works on a different setting, however that's just to identify a fault is limited to the Texecom values.

Think it has to be returned.

Thanks. I tried all of the different settings that are supported by the panel and get the same behaviour each time. I think the unit is therefore faulty and will need to be replaced. I'm still curious what causes a 'tamper' on a working unit as there doesn't seem to be any form of contact switch on the case.

Does the faulty pir light up ?

I suspect its a faulty device as it doesnt follow the location it follows the device.

as to why its faulty I cant see what its doing in terms of resistance etc etc its hard to say.
