The Sargent & Greenleaf Model 6120 combines ease of
operation with security. Its advanced electronic circuit
design makes it easy to open and easy to change codes.
Follow these instructions carefully to get the best
possible use from your lock.
introduction
• The Sargent & Greenleaf Model 6120 Motorized Electronic
Combination Lock is shipped from the factory with a factory
master code only. It is 1 2 3 4 5 6 #. This code is used to
open the lock and set or change all of its codes. If the safe
maker or your dealer sets a new master code, he will advise
you of the change. You should set the lock to your own,
unique master code immediately.
• The Model 6120 will always open on the master code. At your
discretion, it can also be set to accept up to eight different
user codes. The master code holder is responsible for
maintaining the number of active users programmed into
each lock. The master code is designated as code #1, and
the user codes (if set) are designated by user I.D. number 2,
3, 4, 5, 6, 7, 8, and 9. The user codes do not exist until they
are programmed into the lock.
• Each time a button is pressed and the lock accepts the
input, it emits a “chirp,” and the LED on the keypad lights
momentarily.
• All codes must contain six digits or six letters. Any digit or
letter can be used as many times as you wish. For instance,
the following codes (while not recommended) will operate the
lock: 5 5 5 5 5 5 # OR J J J J J J #
• All codes end with #. This signals the lock that you have
finished entering all digits of the code.
• If you pause more than ten seconds between button presses
when entering a code, the lock will assume you do not want
to continue, and it will reset itself. To open the lock, begin
the code entry sequence again from the first step.
• If you realize you have pressed an incorrect button when
entering a code, press
*
or simply pause ten seconds or
more, then begin entering your code again.
• If four incorrect codes are entered in a row, the Model 6120
will shut down for a period of as long as fifteen minutes.*
This is a security feature. Pressing any button anytime during
the lockout period will reset the timer to its maximum penalty
time. Do not touch any keypad buttons for a period of fifteen
minutes, then enter any valid code to open the lock.
* Locks produced before mid 1997 shut down for fifteen minutes. Locks
produced after this shut down for five minutes.
