my panel has developed a fault as follows. keypad shows TA lit constant,DAY lit constant, and power lit constant. Only 3 (any three) number buttons bleep the fourth button gives a flat sound, and the chime, omit, reset, prog, and set are all flat sounds. I would appreciate some help please. Ta, Glen

There's three tamper circuits Aj not just the two you mentioned,

It sounds like a battery issue to me not a system tamper.

TA - Tamper Alarm
One or more sensors or keypads have had the Tamper Alarm activated.you need to put in engineering mode and find which zone/zones are at fault
