I HAVE A MASTER ALARM SYSTEM....AFTER CHANGING THE BACKUP BATTERIES DUE TO ALARM BLEEPING ALL THE TIME,I CANNOT SEEM TO SET IT NOW....ONCE THE NEW BATTERIES ARE PLACED IN THE FACIATHE PANEL BLEEPS TWICE ALL LIGHT INDICATORS ARE LIT EXCEPT THE PANIC BUTTON.THE PANIC BUTTON LIGHT COMES ON WHEN THE FACIA IS PUT BACK ON,AND THE ALARM BLEEPS ONCE EVERY SO OFTEN...AND IS IMPOSIBLE TO SET, OR EVEN CLEAR THE PANEL...ALSO IF I NEED A NEW FACIA WHERE CAN I PURCHASE ONE???..HOPE SOMEONE CAN HELP

The old battery has probably cooked the panel, the only way to get it working is to buy a new one. Post your general location any someone might be able to help.
