Hi Helen,

Check that all covers on the control panel, sensors, etc are securely fitted.

If they are not then you will gt these tamper alerts.

Hi Pete
All the covers are securely fitted.
Expert:  Pete replied 1 year ago.

When did the problem start?

e.g. after a service or after replacing a battery or after a powercut...

Customer: replied 1 year ago.
It was after replacing the battery in the front door sensor.
Expert:  Pete replied 1 year ago.

Ok, first try a system reset if you haven't already done so, by entering the code.

If the error still appears then open the front door sensor again and check the tamper switch to ensure it is not damaged, then fit the cover again and ensure it is making contact with the tamper switch.

Sorry I have no idea how to do a system reset. I don't know much about these things!!
Expert:  Pete replied 1 year ago.

Hi Helen,

Sorry for the delay, just seeing your reply now.

To reset the alarm, try just entering your user code.

Let me know if that works?
