Normal Keypad Operation

:

•  If the user enters a 4-digit code that is matched to one of 

the 25 stored codes. The STATUS light should blink and the 

beeper should beep twice to confirm that a matched code is 
entered. The lock is pulled for 3 sec (factory default). 

•  No more than 20 key presses are allowed to obtain the 4-digit 

entry code. 

Example

1234 is one of the codes stored in one of the memory location. 

The user can enter ‘x1234’ or ‘xxxxxxxxxxxxxxxx1234’ and the 
gate should be activated (x is any key). If more than 20 key 
presses is entered without matching one of the codes then the 

unit’s STATUS light should be flashing rapidly and no entry will 

be accepted for the next 40 seconds.  The user must not enter 
any code for at least 40 seconds before the unit returns to nor-
mal operation; otherwise it remains in this ‘lock-down’ mode.
