I have a problem in that I have changed a broken cover which was not allowing the system to be set as it was showing tamper inactive fault, after swapping cover the message remains the same, any suggestions?

Was the fault Bell Tamper or Global Tamper? Or is the system set for EOL?

Have you tried to reset the panel, also does the sounder have a back tamper

May need an engineer reset. I know the 9651 requires an eng reset on certain conditions of which a bell tamper may be one.

The cover on the bellbox was broken?

As above may need an eng reset, that's an option for sure, but also the message won't just clear by itself.

 

You'll need to enter your user code and acknowledge the fault, IF its user reset it should then reset IF the fault is clear.

yes the bell is only about 8ft of ground level and 4ft from a main road, which was recently resurfaced , I`m assuming that a debris was thrown up and took out about a 3inch hole
