I’ve tryed to do a reset but still goes back to adt heading .when I power up I can use tag to change from alert however when I try to set it displays zone 1 tamper (which I looked out ) but then ask for a manger code which I don’t know .
If I press A it say abort tamper 1001
If I press B it says part set /night set
On the system I have I put in code then A or B does anyone know how to reset this system thanks
