Sargent & Greenleaf 6120 Electronic Lock Instructions

Introduction
• The Sargent & Greenleaf Model 6120 Motorized Electronic Combination Lock is shipped from the factory with a factory master code of 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 10 seconds between pressing buttons when entering a code, the lock will assume you do not want to continue, and it will go into standby mode. To open the lock, begin the code entry
sequence 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 lock will shut down for a period of up to 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.
•The model 6120 does not have audit trail capabilities.
•For UL installations, the maximum number of user codes is one.
Note: This lock has been Listed by Underwriters Laboratories for use with the following S&G keypad(s): 6120-0XX, 6120-2XX, 6120-4XX, 6160-2XX (IP Series), 61KP-1XX, 6130-5XX

To Open the Lock
Press the code digits or letters in order, followed by #. The lock bolt will retract for six seconds, allowing you time to operate the safe handle and open the door. Do not put any pressure on the safe handle until after the code has been entered. The Model 6120 will lock automatically when the safe door is closed and the handle is turned to the locked position.
In Case of Trouble If your lock should fail to open when a valid code is entered, check for the following:
1.  The boltwork of a safe can, under certain conditions, place pressure on the side of the lock’s bolt. This is often caused by something inside the safe pressing against the door or by something caught between the safe door and its frame. When this occurs, the lock will not operate properly. To relieve side pressure on the lock bolt, move the safe’s handle to the fully locked position, then re-enter a working  code. The lock should open.
2.  If the lock makes no sound when any of the keys are pressed, or if the lock “chirps” when keys are pressed, but it will not open, the batteries may be drained to the point that they will not operate the lock’s motor. Follow the battery replacement procedure in this manual.
3.  If the lock makes no sound when any of the keys are pressed, but the batteries have been checked and found to be good, a loose keypad connector may be the cause. If your lock uses the two-battery keypad
(pictured to the left of the lock above), pull the keypad away from the base as described in the battery changing procedure. Check to make sure the wire connector is firmly seated into its receptacle on the keypad circuit board. The connector is designed so that it will only slide into the receptacle when aligned correctly.

If all of the preceding remedies have been exhausted and the lock still does not open, contact a qualified safe technician in your area for professional service.

Security Advisory
If your lock is used many times a day (50 or more openings daily), it is advisable to use as many different keys as possible in your code number. Avoid using a key more than once whenever possible. Check the keypad frequently for visible wear which might indicate which keys are being pressed for code entry. Change the code to use different keys when wear is evident. If necessary, have a qualified service technician replace the keypad.

About Changing Codes
All code changing procedures begin by pressing SG*(the same as 7 4 *), followed by the existing six-digit master code and #. The lock immediately chirps five times.If the lock emits a series of closely spaced chirps (almost a continuous tone) you have made a mistake and must start again. Always keep the safe door open when making programming changes.
To Change the Master Code (code #1)
Press 74 * (existing master code) #  1 * (new m. code) # (new m. code) #
Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the new master code will not be accepted—the old code is retained.
Note: It is very important to remember your master code. If it is lost, the manufacturer of your safe may be able to help you reset the lock. S&G does not retain any lock codes
To Enter or Change a User Code (codes #2—#9)
Press 74* (master code) # (user I.D.) * (new user code) # (new user code) #
Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the new  code will not be accepted. Any existing user code remains.
For instance, if you want to enable the #2 user code (the first user code) to open the lock with a code of 4 4 6 6 3 3, you will use the following procedure.
Press 74* (master-code) # 2 * 446633# 446633#
This same procedure would change any existing #2 user code to 4-4-6-6-3-3.
To Delete a User Code
You may find that a particular user code which you have enabled is no longer needed. It is a good security policy to remove any unneeded codes. To do so, follow this procedure.
Press 74* (master-code) # (user I.D. 2 through 9) * #  (pause) #
Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the user code will not be deleted.
The 6120 lock will not allow you to inadvertently delete the master code.
