Hard reset sequence for E-Plex 3xxx Series:
A)  User knows the Master code:
  1.  Insert mechanical override key, turn to 3 o’clock position, press # and  
    then turn key back to 12 o’clock position within 5 seconds. 
  2.  You have up to 5 seconds to push ‘#’ and then turn key back to 
    12 o’clock position. If 5-second timeout is reached without pressing ‘#’,  
    the lock continues its normal operation. As soon as the ‘#’ is pressed,  
    the lock exits the current state. If timeout is reached or if any other  
    key is pressed after the ‘#’ was pressed, the lock exits the sequence  
    and stays in access state. If ‘#’ is pushed and reset button is released  
    within 5-second period, the lock goes in Reset Sequence State and the  
    lock displays the ‘Reset Sequence In Progress’ message by flashing  
    Green and Red LED alternatively once every second. 
  3.  In this state, users have a 20-second period to enter the Master Code   
    to perform a hard reset. If a bad Master Code is keyed-in, the lock exits  
    the Reset Sequence State and goes back in access state. If the correct  
    Master Code is entered within 20 seconds, the lock performs a hard  
    reset and goes back in unprogrammed state. When an incorrect Master  
    Code is entered, the Tamper Count decrements. After 4 unsuccessful  
    attempts to Reset the lock with a bad Master code, the lock goes in  
    the Tamper Shutdown state for 30 seconds. It will resume normal  
    operations after this delay. If no master code is entered during the    
    20 seconds delay, the lock will enter a 15 minute wait period assuming  
    the Master Code is unknown.
B)  User does not know the Master code:
  1.  Insert mechanical override key, turn to 3 o’clock position, press # and   
    then turn key back to 12 o’clock position within 5 seconds. 
  2.  You have up to 5 seconds to push ‘#’ and then turn key back to 
    12 o’clock position. If 5-second timeout is reached without pressing ‘#’,  
    the lock continues its normal operation. As soon as the ‘#’ is pressed,  
    the lock exits the current state. If timeout is reached or if any other  
    key is pressed after the ‘#’ was pressed, the lock exits the sequence  
    and stays in access state. If ‘#’ is pushed and reset button is release  
    within 5-second period, the lock goes in Reset Sequence State and the  
    lock displays the ‘Reset Sequence In Progress message by flashing  
    Green and Red LED alternatively once every second. 
  3.  In this state, users have a 20-second period to enter the Master Code  
    to perform a hard reset. When the user does not know the master    
    code, the user must not enter anything during that 20 seconds delay.  
    The Reset sequence in progress message will be displayed on the LEDs.
  4.  When the 20 seconds delay will be exhausted, a 15 minutes wait period  
    will begin. During that state, any operation on the lock will be ignored  
    (green LED will not blink when pressing keys) and the Green and Red 
    LED will blink once a minute.
