If it is because the keys are sticking and you keep setting it off.
Change the code.
Otherwise your stuffed not made for years now.
However a latter version will work with the panel.
Look for a 9851 compatible keypad. If yours is running the later software this should work. But it is hit and miss.
As above if its sticking keys change the code. Or if your careful split the keypad and clean the membrane.
The rest are tarts and could not be bothered to type :D

As precise information is not being given, I'll won't go down the Q/A response any more - waste of time.
The 9800 has been obsolete for years, work it out.
