Tamper Fault

[danfoss01]

Hi fOLKS,
Similar to the 'False Alarm Hell' thread,we were getting random Tamper faults so had the system checked.All looked fine (Keypad,PIR's,Bell Box ,battery etc) no sign of loose wires or corrosion - so as a last resort we got the Tamper circuits disabled.
All fine for twelve months but now in the past couple of days there have been two Tamper faults (alarm was set during one,unset during another),but all the Tamper circuits are still disabled.

Any idea what could cause this?

Edit - it's an Ademco Accord 8 system.

Seen as you mention tampers, i'll assume you haven't got it wired with resistors.

There's the tamper for the zones, bell tamper, keypad tamper and the the end station tamper. Have you got the long thin keypad or the square one?

Open the panel and see what's been linked out, taking the usual safety precautions as there is mains present. As far as i know, the keypad tamper can't be linked out as it's incorporated in the data line, which leaves the other 3.

Alternatively see if the log can give you any information.

It's the square keypad.

I'm sure the engineer told me all were linked out,and given that we had no bother for twelve months I assumed that was the case.

The log just illuminates the Tamper light and bleeps - no other info

I'll have to get him out again.

I do know that all the Tamper switches were 100% - they definitely weren't being triggered by movement of any kind
