Texecom Premier - AUX 0 Tamper

[fiscoking]

Hello,

 

Got a 'AUX 0 Tamper' out of the blue today on a remote LCD keypad. No changes to the alarm, which has been installed for about 17 years. Battery 12 months old.

 

The premier installation manual has this on the event log description:

 

AUX # Tamper An Auxiliary Tamper input from device # has been activated

 

Which doesn't say a lot.

 

Q> Does this mean the Aux Tamper circuit on the main PCB has gone open circuit? picture below.

 

There's another tamper for the bell box, but that has its own event log message, as does the control panel lid.

 

It's an intermittent fault, so hard to trace. Want to make sure I'm looking at the correct circuit.

 

There were no self tests in the event log. System voltage is correct so the regulator hasn't gone either.

 

Thanks.

Disconnect it and see if you get the same event message?

What's wired into the AUX Tamper?

>>What's wired into the AUX Tamper?

 

All of the internal PIR tampers are daisy chained (serially). So about 10 PIRs. But they only use micro switches for the tamper. Difficult to see how any of those could malfunction. Could also be a loose connection.

 

I just wanted to know if the 'AUX Tamper' on the PCB was the same as 'AUX 0'.

 

As James Wilson said above, I might have to open the case on a PIR to see if I get the same warning.

 

After that, I'll jumper the tamper on the main PCB and see if I get the same problem. If I do then it's an issue with the main PCB and not any of the tamper switches or wiring.

JW said open the wiring on the PCB first to see if you get same warning

For Global tamper you have to break them open to measure and compare to as fitted readings for each pair....

It's a Premier so you could go wire them all FSL/EOL then you can narrow the fault down.

It may even fix it if one of the tamper pairs are faulty.

Yes you can double check by opening it but that is the Aux Tamper.

10 PIR's on 8 zones is asking for trouble.
