Don't know codes but power went out two beeps keep going off

After a power outage, the DSC PC1555MX alarm system uses beeping codes to indicate system status. If the [A] key is held for two seconds, the panel beeps three times to confirm activation. When communication to the central station is successful (kissoff received), the keypad beeps ten times rapidly. Arming is not allowed if there is an AC or battery trouble condition.
