My Keypad Reads Tamper.
An attempt is made to remove the housing from the input panel, a tamper-detect switch disables the lock.
When in tamper alarm, a manager PIN code is required to clear it and open the lock. Any other valid user codes will not work, and the LCD will flash TAMPER ALARM for 15 seconds.
To clear the alarm, enter the manager code once. The TAMPER ALARM message displays on the LCD. Re-enter the same manager code within 10 seconds to disable the tamper alarm and open the lock.
